Description

Method for controlling airflow volume and flow direction from a remote heat exchanger unit of a transport climate control system

Technical Field

Embodiments disclosed herein relate generally to a transport climate control system (transport climate control system, TCS). In particular, embodiments described herein relate to methods and systems for controlling airflow volume and flow direction from a remote heat exchanger unit of a transport climate control system.

Background

Transport climate control systems (TCSs) are commonly used to control environmental conditions (e.g., temperature, humidity, air quality, etc.) within a transport unit (e.g., a container on a flatbed, intermodal container, etc.), a truck, a van, or other similar transport unit). In some embodiments, the transport unit may include a plurality of zones, and the TCS may be a multi-zone TCS (MTCS) configured to provide independent climate control to each of the plurality of zones within the transport unit.

Disclosure of Invention

Embodiments disclosed herein relate generally to transportation climate control systems (TCSs). In particular, embodiments described herein relate to methods and systems for controlling airflow volume and flow direction from a remote heat exchanger unit of a transport climate control system.

Embodiments described and described herein relate generally to implementing one or more remote heat exchanger units within a climate-controlled space, wherein each remote heat exchanger unit is capable of distributing a configurable airflow based on environmental conditions in at least a portion of the climate-controlled space of a transport unit.

In particular, embodiments described herein may allow for a configurable remote heat exchanger unit that may adjust an airflow discharge arrangement to provide an optimal airflow within a climate-controlled space based on environmental conditions (e.g., spacing of cargo, temperature within a portion of the climate-controlled space, and/or physical layout of the climate-controlled space).

Embodiments for controlling the flow volume and/or direction of a gas to eliminate manual configuration of a configurable remote heat exchanger or corresponding damper are described and described herein. Thus, the organizational burden of the customer remembering to manually reconfigure the airflow, and the physical burden of doing so, can be reduced. Still further, since airflow management will be automatic, the need for customers to train operators to do so will be obviated.

Still further, the embodiments described herein for controlling the flow volume and/or direction of a gas may be considered an advancement in the temperature management of a climate controlled space or one or more zones of a climate controlled space. For example, upon sensing or detecting a need to reduce the temperature within a given climate controlled space, e.g., to preserve cargo, the temperature may be reduced more quickly as managed by the embodiments described and recited herein.

In one embodiment, a method for controlling airflow volume and flow direction from a remote heat exchanger of a transport climate control system includes: the controller receives data from sensors within at least a portion of the climate controlled space, wherein the received data is indicative of a position of a bulkhead within the climate controlled space relative to a position of the remote heat exchanger; determining a volume of airflow from the remote heat exchanger unit and determining a flow direction based on the received data; and instructing the remote heat exchanger to provide the determined airflow volume and the determined flow direction; and the remote heat exchanger receives instructions from the controller and adjusts operation based on the instructions to provide the determined airflow volume and the determined flow direction.

Detailed Description

Embodiments for controlling the flow volume and/or direction of a gas to eliminate manual configuration of a configurable remote heat exchanger or corresponding damper are described and described herein. Thus, the organizational burden of the customer to remember to manually reconfigure the airflow, and the physical burden of doing so, can be eliminated. Still further, since airflow management will be automatic, the need for customers to train operators to do so will be obviated.

Still further, embodiments described herein for controlling the flow volume and/or direction of a gas may be considered an improvement in the temperature management of a climate controlled space or one or more zones of a climate controlled space. For example, upon sensing or detecting a need to reduce the temperature within a given climate controlled space, such as to preserve cargo, the temperature may be reduced more quickly as managed by the embodiments described and recited herein.

The embodiments described and/or illustrated herein may refer to the accompanying figures; however, such embodiments are non-limiting examples, which may also be embodied in various other forms. Well-known functions or constructions are not described in detail to avoid unnecessarily obscuring the invention. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art how to variously employ the present invention in virtually any appropriately detailed structure. In the description and drawings, like reference numerals identify elements that perform the same, similar or equivalent functions.

Further, since the example embodiments illustrated, described, and described herein are not intended to be limiting, it should be understood that the corresponding configurations are changeable. As an example, in a non-limiting alternative embodiment, a duct or air flow illustrated as being directed to the left may be directed to the right, and vice versa. It should be appreciated that in other non-limiting embodiments, the duct or air flow may be directed in any direction desired for a particular implementation. Thus, it should be understood that the number of permutations of embodiments according to example embodiments is substantial.

The scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given herein. For example, not all elements may be required to practice the invention unless specifically described herein as "critical" or "required.

The embodiments described and described herein relate generally to providing a remote heat exchanger unit that is configurable to improve or even optimize air distribution within a given zone of a climate controlled space. Embodiments include and provide for configurable airflow direction of conditioned air exiting a remote heat exchanger unit and improved or even optimized temperature distribution within a climate controlled space.

TCS is typically used to control environmental conditions (e.g., temperature, humidity, air quality, etc.) within a transport unit (e.g., a container on a flatbed, intermodal container, etc.), a truck, a van, or other similar transport unit). The transport unit may include a plurality of zones and the TCS may be a multi-zone TCS (MTCS). Each zone may require different climatic conditions (e.g., temperature, humidity, air quality, etc.) than one or more other zones. The MTCS can be configured to provide independent climate control to each of a plurality of zones within a transportation unit.

The MTCS can have a main unit and one or more remote heat exchanger units respectively configured to provide climate control to each of one or more zones within a multi-zone transport unit. The transport climate control unit (TCU) of the MTCS may include a compressor, an expansion valve, a first heat exchanger (e.g., a condenser), and a main heat exchanger unit. The main heat exchanger unit may include: a second heat exchanger (e.g., a main heat exchanger); one or more fans for providing climate control within the particular zone in which the main heat exchanger unit is located; one or more flow regulators (e.g., one or more solenoid valves, etc.) for controlling the amount of working fluid (e.g., refrigerant) flow into the main heat exchanger unit; and one or more throttling devices (e.g., one or more electronic throttles, etc.) for controlling the amount of working fluid flow available to the suction side of the compressor of the MTCS.

Each remote heat exchanger unit may have: remote heat exchangers (e.g., heat exchanger coils); one or more fans for providing climate control within the particular zone in which the remote heat exchanger unit is located; one or more flow regulating devices (e.g., one or more solenoid valves, etc.) for controlling the amount of working fluid flow entering the remote heat exchanger unit; and one or more throttling devices (e.g., one or more electronic throttles, etc.) for controlling the amount of working fluid flow available to the suction side of the compressor of the MTCS. Each remote heat exchanger unit may be connected to the TCU via a common working fluid line. A remote heat exchanger unit may be used to provide climate control for a region of the transport unit.

The MTCS can be used, for example, to cool, heat, and defrost two or more zones of a transportation unit. Note that in some cases, a remote heat exchanger unit may have two or more remote heat exchangers (e.g., a first heat exchanger coil and a second heat exchanger coil connected in parallel or in series).

The MTCS includes a working fluid line and a controller (e.g., an MTCS controller) configured to manage, command, direct, and regulate the behavior of one or more components (e.g., evaporator, condenser, compressor, expansion device, etc.) of the working fluid line. The MTCS controller can also be configured to manage, command, direct, and regulate the behavior of the main heat exchanger unit and one or more remote heat exchanger units. The MTCS may generally be a vapor compressor type refrigeration system, or may be any other suitable climate control system using a working fluid, cold plate technology, or the like.

Fig. 1 illustrates one embodiment of an MTCS 100 for a Transport Unit (TU) 125, which transport unit 125 may be towed, for example, by a tractor (not shown), according to one or more non-limiting example embodiments of a remote heat exchanger unit with configurable air discharge. The MTCS 100 includes a transport climate control unit (TCU) 110 that provides environmental control (e.g., temperature, humidity, air quality, etc.) within a climate controlled space 150 of TU 125. The MTCS 100 also includes an MTCS controller 170 and one or more sensors (not shown) configured to measure one or more parameters of the MTCS 100 and to communicate the parameter data to the MTCS controller 170. The MTCS 100 is powered by a power source 112. The TCU 110 is disposed on a front wall 130 of the TU 125. In other embodiments, it should be appreciated that the TCU 110 may be disposed, for example, on the roof 126 or another wall of the TU 125.

The TU 125 shown in fig. 1 is a trailer unit. However, it should be understood that the embodiments described herein are not limited to truck and trailer units, but may be applied to any other type of transportation unit (e.g., containers on flatbed, intermodal containers, etc.), trucks, vans, or other similar transportation units.

Programmable MTCS controller 170 can comprise a single integrated control unit or can comprise a distributed network of TCS control elements. The number of distributed control elements in a given network may depend on the particular application of the principles described herein. An MTCS controller 170 is configured to control the operation of MTCS 100.

As shown in FIG. 1, a power source 112 is disposed in the TCU 110. In other embodiments, the power source 112 may be separate from the TCU 110. Moreover, in some embodiments, the power source 112 may include two or more different power sources disposed inside or outside the TCU 110. In some embodiments, power source 112 may include an internal combustion engine, a battery, an alternator, a generator, a solar panel, a fuel cell, and the like. When power source 112 includes an internal combustion engine, the internal combustion engine may be, for example, a two-speed engine, a variable speed engine, or the like.

The climate controlled space 150 is divided into a plurality of zones 152. The term "zone" refers to a portion of the area of the climate controlled space 150 that is separated by walls 175. In some examples, each zone 152 may maintain a set of environmental condition parameters (e.g., temperature, humidity, air quality, etc.) independent of other zones 152.

Note that in fig. 1, the climate controlled space 150 is divided into three zones: a first region 152a; a second region 152b; and a third region 152c. The various regions 152 shown in fig. 1 are divided into approximately equal areas. However, it should be appreciated that the climate controlled space 150 may be divided into any number of zones in any size configuration suitable for environmental control of the different zones.

The MTCS 100 is configured to control and maintain individual environmental condition requirements in each zone 152. The MTCS 100 includes: a main heat exchanger unit 111 disposed within the TCU 110 for providing climate control within the first zone 152 a; and a plurality of remote heat exchanger units 180 disposed in TU 125. That is, the first remote heat exchanger unit 180a is disposed in the second zone 152b, and the second remote heat exchanger unit 180b is disposed in the third zone 152 c. The main heat exchanger unit 111 and the remote heat exchanger unit 180 are collectively referred to herein as heat exchanger units. In some embodiments, each of the first, second, and third zones 152a, 152b, 152c may be a chilled temperature zone operating to maintain a temperature set point within a chilled temperature range or a fresh temperature zone operating to maintain a temperature set point within a fresh temperature range. In one embodiment, for example, the freezing temperature range may be between about-25°f and about 15°f, and the fresh temperature range may be between about 16°f and about 90°f. In another embodiment, for example, the freezing temperature range may be between about-25°f and about 24°f, and the fresh temperature zone may be between about 26°f and about 90°f. It should be appreciated that any of the first zone 152a, the second zone 152b, and the third zone 152c may be a fresh temperature zone operating to maintain a temperature set point within a fresh temperature range or a chilled temperature zone operating to maintain a temperature set point within a chilled temperature range.

Each remote heat exchanger unit 180a, 180b is fluidly connected to the main heat exchanger unit 111. The main heat exchanger unit 111 and the respective remote heat exchanger units 180a, 180b may include: one or more heat exchanger coils; one or more fans for providing climate control within the particular zone in which the heat exchanger unit is located; one or more flow regulators (e.g., one or more solenoid valves, etc.) for controlling the amount of working fluid flow into the heat exchanger unit; and one or more throttling devices (e.g., one or more electronic throttles, etc.) for controlling the amount of working fluid flow available to the suction side of the compressor of MTCS 100. The HEAT exchange units (e.g., the main HEAT exchanger unit 111 and the respective remote HEAT exchanger units 180) may operate in a plurality of modes of operation (e.g., a NULL mode, a run NULL mode, a COOL (COOL) mode, a HEAT mode, a DEFROST (DEFROST) mode, a low fan speed mode, a high engine speed mode, a low engine speed mode, etc.).

Additional details of the remote heat exchanger units 180a, 180B are described below with reference to fig. 2A-15B.

Fig. 2A illustrates a schematic diagram of an exemplary architecture of a remote heat exchanger unit 200 with configurable air venting in accordance with at least one exemplary embodiment described and recited herein. Fig. 2A shows configuration views of examples (i) - (iv) for variable configuration of remote heat exchanger unit 200, as described below.

As depicted in fig. 2A, a non-limiting example embodiment of a remote heat exchanger unit 200 may include: an air inlet, for example, a bottom air inlet 202A or a top air inlet 202B; at least one heat exchanger coil 205 through which air received through one or both of the air inlets 202A or 202B is directed to the air outlet 212; one or more fans, such as fans 210A and 210B, that direct air received through the at least one air inlet 202A, 202B through the at least one heat exchanger coil 205; and a separable air duct system 215 that variably directs conditioned air received from the air outlet 212 out of the remote heat exchanger unit 200.

The air inlet 202, which may alternatively be referred to as an air return inlet, may refer to one or more openings through which air is received into the remote heat exchanger unit 200. According to example embodiments described and recited herein, an embodiment of the remote heat exchanger unit 200 may include at least one of a bottom air inlet 202A disposed on a bottom of the remote heat exchanger unit 200 and a top air inlet 202B disposed on a top of the remote heat exchanger unit 200. However, the embodiments described, recited, and even suggested herein are not so limited. The air inlet 202 may also be disposed on any surface of the remote heat exchanger unit 200, such as a side, particularly when the remote heat exchanger unit 200 is not limited to a square or rectangular configuration.

The heat exchanger coil 205 may refer to one or more heat exchanger coils disposed within the remote heat exchanger unit 200 to receive air from the conditioned space blown by a heat exchanger blower (not shown) and to recondition the received air as it is blown through the heat exchanger coil 205. The reconditioned air may then be directed to the air outlet 212.

Although not limiting, as described and recited herein, unless otherwise indicated or specified, various embodiments of the heat exchanger coil 205 may be understood as having associated therewith corresponding drain tanks, heating systems, liquid line solenoid valves, blowers, and the like.

The fan 210 may refer to a fan that blows air received through the one or more air inlets 202 across the one or more heat exchanger coils 205 toward the air outlets 212.

According to all of the example embodiments described and depicted herein, alternatives thereof may include a bi-directional fan 210 that may be rotated in a clockwise or counter-clockwise direction.

Accordingly, alternative embodiments including a bi-directional fan 210 may have symmetrical fan blades, thereby effectively controlling the direction of airflow affected by the bi-directional fan 210, depending on, for example, the direction of rotation of the fan blades.

The air outlet 212 may refer to an opening in the remote heat exchanger unit 200 that partially regulates the discharge of conditioned air from the remote heat exchanger unit 200. Thus, the climate controlled air (e.g., cooling air, heating air, etc.) exiting the air outlet 212 may be directed back into the conditioned space where it will exchange heat with the air from the climate controlled space and maintain the climate controlled space at a desired temperature. According to a non-limiting example embodiment of the variations described and depicted herein, the remote heat exchanger unit 200 may have one or more air outlets 212. For example, for embodiments having two heat exchanger coils 205, the remote heat exchanger unit 200 may include an air outlet 212 corresponding to each of the plurality of heat exchanger coils 205.

The separable air ductwork 215 can refer to ductwork that facilitates a configurable direction of airflow based on the placement of the heat exchanger coils 205 in their environment (e.g., within a climate controlled space).

The air duct inlet 220 may refer to an opening in the separable air duct system 215 through which air respectively directed through the heat exchanger coil 205 and through the air outlet 212 may be directed in a desired direction into the environment of the remote heat exchanger unit 200.

Throughout the drawings and their description, there may be depictions and/or descriptions of a number of features, such as, but not limited to, fans 210A and 210B; air duct inlets 220A, 220B, and 220C; etc. However, the embodiments depicted, described, or described herein are not so limited in terms of the number of features shown and disclosed with respect to the various embodiments of the remote heat exchanger unit 200. Thus, unless the context requires otherwise, the description and recitation herein may refer to such features in the singular, for example, one or more fans 210, one or more air duct inlets 220, etc., without limiting the scope of any embodiments depicted, described, or recited herein.

Examples figures 2A-i through 2A-iv include a heat exchanger coil 205. Air discharged from the air outlets 212 may be directed to a separable air duct system 215 having, for example, air outlets 2160A, 2160B, and 2160C.

Example fig. 2A-i illustrate a separable air duct system 215 configured to discharge air from an air outlet 212 from a single opening (e.g., opening 2160A) by blocking airflow at any two of openings 2160A, 2160B, and 2160C. In the figure, the opening 2160C is blocked.

Example figures 2A-ii illustrate a separable air duct system 215 configured to discharge air from the air outlet 212 through all available openings (e.g., openings 2160A-C) by opening all openings 2160A-C.

Example fig. 2A-iii illustrate a separable air duct system 215 configured to discharge air from the air outlet 212 from opposing lateral openings (e.g., openings 2160A and B) by blocking any of the openings 2160A-C. In the figure, the opening 2160B is blocked.

Example figures 2A-iv illustrate side views of a remote heat exchanger unit 200.

Fig. 2B shows a schematic diagram of a separable air duct system 215 according to an example embodiment described and depicted herein.

As depicted, non-limiting example embodiments of separable air duct system 215 may include, for example, air duct inlets 220A-C, ducts 2150A-C, baffles 2155A-C, and air duct outlets 2160A-C.

Air duct inlets 220A-C may refer to openings in separable air duct system 215 that may be connected to air outlets 212 corresponding to remote heat exchanger units 200. The separable air duct system 215 may be sealed, attached, or otherwise connected to the remote heat exchanger unit 200 such that substantially all of the air flowing through the air outlet 212 is directed into the separable air duct system 215, and more particularly into one or more of the air duct inlets 220A-C.

According to at least some example embodiments described and recited herein, the air outlet 212 may include a series of openings, e.g., each of the air duct inlets 220A-C sealed, attached, or otherwise connected to the series of openings; or the air outlet 212 may be configured as a single opening with one or more of the air duct inlets 220A-C sealed, attached, or otherwise connected to portions of the single opening.

According to at least some example embodiments described and recited herein, one or more of the air outlets 212A-C may have louvers or dampers 2175A-C attached, which may be variably opened or closed to thereby manually or automatically adjust the air flow from the respective air duct outlets.

Although not limiting, as described and depicted herein, unless otherwise indicated or specified, each occurrence of one or more air outlets 212 described as closed may be understood to mean that the corresponding damper 2175 has been or remains closed.

As previously described, according to all of the example embodiments described and recited herein, alternatives may include one or more bi-directional fans 210X that exhaust airflow in one direction or the opposite direction (e.g., left to right or right to left). In some embodiments, each of the one or more bi-directional fans 210X may be an axial flow fan capable of rotating in a clockwise or counter-clockwise direction. In various embodiments, each of the one or more bi-directional fans 210X may be an axial flow fan, a blower, an impeller fan, or the like.

Accordingly, the alternative embodiment of fig. 16A and 16B includes a bi-directional fan 210X that may have symmetrical fan blades to effectively control the direction of airflow affected by the bi-directional fan 210X depending on, for example, the direction of rotation of the fan blades. The design of the bi-directional fan 210X enables a single discharge implementation (as in fig. 16A and 16B) in which the air flows through both heat exchangers 205XA, 205XB flow in the same direction. The design of the bi-directional fan 210X also enables a double discharge implementation (fig. 17A and 17B) in which the air flows through the two heat exchangers 205XA, 205XB flow in opposite directions. Further, unlike other embodiments described and/or recited herein, no damper is required and the emissions may be interchanged. The embodiments illustrated in fig. 16A, 16B, 17A, and 17B and described and/or recited further herein are not limited to two embodiments of bi-directional fan 210X. In contrast, there are many embodiments, for example, implemented by the bi-directional fan 210X on the order of a multiple of two or three.

Fig. 16A shows a schematic diagram illustrating the unidirectional discharge of air from a remote heat exchanger unit, e.g. right to left. A portion of the return air 1605 passes through the heat exchanger coil 205XA and is drawn by the bi-directional fan 210XA to be discharged as air 1610A that has been heat exchanged with the heat exchanger coil 205 XA; and another portion of the return air 1605 is drawn by the bi-directional fan 210XB and passed through the heat exchanger coil 205XB to be discharged as air 1610B that has been heat exchanged with the heat exchanger coil 205 XA.

Fig. 16B shows a schematic illustrating the unidirectional discharge of air from a remote heat exchanger unit, e.g., from left to right. A portion of the return air 1605 is drawn by the bi-directional fan 210XA and passed through the heat exchanger coil 205XA to be discharged as air 1610A that has been heat exchanged with the heat exchanger coil 205 XA; another portion of the return air 1605 passes through the heat exchanger coil 205XB and is drawn by the bi-directional fan 210XB to be discharged as air 1610B that has been heat exchanged with the heat exchanger coil 205 XB.

For the example embodiment of fig. 16A and 16B that implements unidirectional air discharge, the symmetrical fan blades of bi-directional fans 210XA and 210XB rotate in a common direction depending on the intended discharge direction.

As previously mentioned, according to all example embodiments described and recited herein, alternatives thereof may include: one or more bi-directional fans 210X that exhaust air flow through, for example, heat exchange from one or more heat exchanger coils disposed below the fans 210X; and/or one or more bi-directional fans 210X that exhaust air flow through a plurality of heat exchangers that may be disposed below or beside the respective fans.

In various embodiments, each of the one or more bi-directional fans 210X may be an axial flow fan, a blower, an impeller fan, or the like.

Fig. 17A shows a schematic diagram illustrating bi-directional venting of air from a remote heat exchanger unit. A portion of the warm return air 1705A passes from right to left through the coil 205XA and is drawn by the bi-directional fan 210XA to be expelled to the left as cool air 1710A; and another portion of warm return air 1705B is drawn through coil 205XB from left to right and through bi-directional fan 210XB to be drawn to the right as cool air 1710B.

Fig. 17B shows a schematic diagram illustrating bi-directional venting of air from a remote heat exchanger unit. A portion of the warm return air 1705A passes from left to right through the coil 205XA and is drawn by the bi-directional fan 210XA to be expelled to the right as cool air 1710A; and another portion of warm return air 1705B is drawn from right to left through coil 205XB and through bi-directional fan 210XB to be expelled to the left as cool air 1710B.

For the example embodiment of fig. 17A and 17B that implements bi-directional air discharge, the symmetrical fan blades of bi-directional fans 210XA and 210XB rotate in opposite directions according to the respective intended discharge directions.

Fig. 18A shows a side view of a schematic drawing of a remote heat exchanger unit 1800 drawing through a coil design controlling airflow direction. As the air 1805 passes through the coil 205YA, the fan 210YA may draw the air 1805 therethrough to exit as air 1810A. Moreover, the fan 210YB may be turned off and/or intentionally blocked, for example, by an optional baffle or damper, to provide unidirectional discharge of air. It should be appreciated that in other embodiments, the fan 210YB may draw air 1805 therethrough to be expelled as air 1810B. Moreover, the fan 210YA may be turned off and/or intentionally blocked, for example, by an optional baffle or damper, to provide unidirectional discharge of air. It should be appreciated that in some embodiments, both fans 210YA and 210YB may draw air 1805 therethrough to be expelled as air 1810A, 1810B, respectively, providing bi-directional discharge of air.

Moreover, when the remote heat exchanger unit 1800 includes an optional flapper or damper to block the flow of air exiting therethrough, the optional flapper or damper may be fully open, fully closed, or partially open, as desired for a particular application. Similarly, one or both of fans 210YA and 210YB may be turned on at a reduced speed, thus resulting in a greater discharge of air drawn by fans operating at higher speeds and a smaller discharge of air drawn by fans operating at lower speeds. If both fans 210YA and 210YB are turned on at a reduced rate, the discharge of air drawn by the respective fans may be substantially similar.

Fig. 18B shows a top view of a schematic drawing of a suction through coil design for a remote heat exchanger unit 1800 that allows for one or two-way venting of air in accordance with at least the example embodiment of fig. 18A. As the air 1805 passes through the coils 205YA and 205YB, the fans 210YA and 210YB may draw the air 1805 from the two coils therethrough to be expelled as air 1810A and 1810B in both the left and right directions, respectively. As described above, either of the fans 210YA, 210YB may be turned off and/or intentionally blocked, for example, by an optional damper or door. It should be appreciated that in some embodiments, each of the fans 210YA, 210YB may be an axial flow fan, a blower, an impeller fan, or the like.

Fig. 19A shows a side view of a schematic drawing of a remote heat exchanger unit 1900 controlling airflow direction drawing through a coil design. As the air 1905 passes through the coil 205YA, fans 210YA and 210YB stacked on top of the coil 205YA may draw the air 1905 therethrough to be expelled as air 1910A and 1910B in both the left and right directions. Thus, fig. 19A illustrates the bi-directional discharge of air. As noted above, it should be appreciated that in some embodiments, each of the one or more bi-directional fans 210X may be an axial flow fan, a blower, an impeller fan, or the like.

Also, similar to the embodiment of fig. 18A and 18B, the remote heat exchanger unit 1900 may optionally include a damper or door to block the flow of air exiting therethrough, and the optional damper or door may be fully open, fully closed, or partially open, as desired for a particular application. Similarly, one or both of fans 210YA and 210YB may be turned on at a reduced speed, thus resulting in a greater discharge of air drawn by fans operating at higher speeds and a smaller discharge of air drawn by fans operating at lower speeds. If both fans 210YA and 210YB are turned on at a reduced rate, the discharge of air drawn by the respective fans may be substantially similar.

Fig. 19B shows a top view of bi-directional air discharge according to the example embodiment of fig. 19A.

The sensor 2005 may refer to one or more sensors that may be affixed to or otherwise disposed on/within a remote evaporator previously described and recited herein, or to one or more portions of a climate controlled space of a transport unit. Non-limiting examples of sensors 2005 may include, but are not limited to, proximity sensor 2005A (contact or non-contact), thermal sensor 2005B, or 3D spatially mapped sensor 2005C. The 3D space map sensor 2005C can sense or determine the spatial volume of the remote evaporator and the placement of cargo embedded or attached relative to the sensor 2005C. Further, the sensor 2005 may be a resistive, inductive, or encoder type.

The position or proximity sensor 2005A is described below.

As mentioned herein, a position sensor may be considered a potentiometer having a slide (window) contact coupled to a mechanical shaft, which may be angular (rotational) or linear (slider type) in its movement. The slider contact may cause a change in the resistance value between the slider/slider and the two end connections, thereby producing an electrical signal output that has a proportional relationship between the actual slider position on the resistive track and its resistance value. I.e. the resistance is proportional to the position.

As mentioned herein, an inductive position sensor may be considered a linear variable differential transformer. Such a sensor is an inductive position sensor that measures movement. The movable soft ferromagnetic core (i.e., armature) may be connected to the object being measured and may slide or move up and down within the tubular body of the linear variable differential transformer.

As mentioned herein, a rotary encoder is another type of position sensor that is similar to a potentiometer, but is a non-contact optical device that converts the angular position of a rotating shaft into an analog or digital data code (i.e., converts mechanical movement into an electrical signal). Light from an LED or infrared light source may pass through a rotating high resolution code wheel having a desired code pattern, which may be binary, gray code or BCD. The photodetector can scan the disk as it rotates, and the electronic circuit processes the information into digital form as a stream of binary output pulses fed to a counter or controller that determines the actual angular position of the shaft. Rotary optical encoders may be classified as incremental encoders or absolute position encoders.

Tachometers are simplified incremental encoders having a square wave output and are often used in unidirectional applications where basic position or velocity information is required. Quadrature encoders or sine wave encoders are a common form thereof and have two output square waves commonly referred to as channel a and channel B. This device uses two photodetectors slightly offset from each other by 90 deg., thereby producing two separate sine and cosine output signals.

The absolute position encoder provides a unique output code for each rotational position, indicating both position and direction. The corresponding code wheel comprises a plurality of concentric tracks of light and dark segments. Each track is independent of the other with its own photodetector to read the unique coded position value for each angle of movement simultaneously. The multiple tracks on the disc correspond to encoded binary bit resolution such that, for example, a 12-bit absolute encoder will have 12 tracks and the same encoded value will occur once per revolution.

As mentioned herein, an inductive proximity sensor may include: an oscillator that generates an electromagnetic field; a coil that generates a magnetic field; a detection circuit that detects a change in magnetic field when an object enters the magnetic field; and an output circuit that generates an output signal having a normally closed contact or a normally open contact.

As mentioned herein, a photosensor generates an output signal indicative of light intensity by measuring radiant energy (i.e., light) present in a narrow frequency range and radiant energy in a frequency range from infrared to visible ultraviolet. Thus, a photosensor is a passive device that converts light energy (whether visible or infrared portions of the spectrum) into an electrical signal output. Photosensors are more commonly referred to as optoelectronic devices or photosensors because they convert light energy (i.e., photons) into electricity (i.e., electrons).

As mentioned herein, the non-contact linear distance sensor may be mounted or attached to various embodiments of the remote heat exchanger 200, or mounted on a side wall or top wall or bottom wall of the transport unit 20 within the climate-controlled space, such that the linear distance sensor is capable of measuring the distance to the corresponding bulkhead 25. The measured distance may be sent from sensor 2005A to controller 2010 to control the volume and/or direction of the air flow from remote heat exchanger 200. Other types of distance sensors include ultrasound, infrared, laser, etc.

Ultrasonic distance sensors detect the distance of an object by using high frequency sound waves emitted therefrom. That is, the ultrasonic sensor emits a high-frequency acoustic wave toward the target object, wherein the emission time is marked; the sound waves are reflected from the target object back to the ultrasonic sensor; a receiver corresponding to the ultrasonic sensor receives the acoustic wave from the target object, wherein the reception time is marked; and dividing the amount of time spent between transmission and reception by the speed of sound to determine the distance from the ultrasonic sensor to the target object.

Infrared distance sensors detect the distance of an object by using the principle of triangulation (i.e. measuring distance based on the angle of the reflected beam). Thus, when infrared light is emitted from the infrared LED emitter corresponding to the sensor toward the target object, the infrared light beam hits the object P1 and is reflected therefrom at an angle; the back-reflected light is received at the infrared sensor, which then uses the principle of triangulation to determine the location and/or distance of the target object.

The laser distance sensor detects the distance to the object by using the light wave emitted from the laser. Thus, laser light is emitted from a transmitter corresponding to the laser sensor toward the target object, wherein the emission time is marked; the laser pulses are reflected back from the target object; and receiving the back-reflected pulse at the laser sensor, wherein the time of receipt is marked, and then the laser sensor determines the position and/or distance of the target object based on a relationship between the constant speed of light in air and the time measured between the emission of the laser light and the receipt of the reflected pulse.

Unless the context requires otherwise, the following description of an exemplary environment for a remote vaporizer automation system may include a reference to "sensor 2005" without unduly limiting embodiments to one of a proximity sensor, a thermal sensor, or a 3D space mapping sensor.

In some embodiments, the transport unit may have a roll-up door or a swing back door and/or side door. The type and placement of the doors is a factor to consider for the number of zones of the climate controlled space and thus the number and location of the remote evaporator and the one or more sensors 2005 to be installed.

The controller 2010 may refer to one or more processing units embedded within a remote vaporizer. According to at least one non-limiting embodiment, the controller 2010 may be a local processing unit or alternatively may be a client device communicatively coupled to a master unit attached to a remote evaporator. Alternative embodiments contemplate that the main unit is located at a remote location outside the transport unit.

Regardless, the controller 2010 may receive signals from one or more of the sensors 2005 or hosts thereof and then rationally control the volume and/or direction of airflow from the remote evaporator based on the received signals. The signal may indicate, for example, an insufficient temperature for cargo approaching the remote evaporator; and the controlled remote evaporator may be located proximate to the sensor 2005 from which the signal is received.

The actuator 2015 may refer to an electrically activated actuator according to embodiments of the remote evaporator described and described herein that controls the volume of air and/or the direction of air flowing from one or more ducts of the remote evaporator, for example, by controlling one or more corresponding dampers. Thus, actuation may be performed upon receipt of an instruction from the controller 2010.

The non-limiting example embodiment of fig. 21A and 21B shows an arrangement of proximity sensor 2005A by which the probe end of proximity sensor 2005A is permanently or temporarily fixed (e.g., magnetically) to diaphragm 25A or 25B and the other end of sensor 2005A is permanently or temporarily attached to the side or top inside zone 20 (e.g., 20B or 20C), e.g., in insulating slot 251. According to at least one example embodiment, the probe end of the sensor 2005 may be mounted in an assembly of the remote heat exchanger 200 itself.

As diaphragm 25B moves away from or toward remote heat exchanger 200C, the extendable portion of sensor 2005A also moves, and sensor 2005A sends a signal indicative of such movement to controller 2010. For example, sensor 2005A may provide pre-calibrated output data based on the position of diaphragm 25B; and the volume of the exhaust gas flow and/or its direction may be controlled remotely and automatically based on the relative position of the partition 25B within the climate controlled space.

In the non-limiting example of fig. 21A and 21B, when sensor 2005A determines that baffle 25B is disposed in close proximity to remote heat exchanger 200C and thus reduces the space therebetween, sensor 2005A may send data to controller 2010 which causes a damper in remote heat exchanger 200C to direct the flow of air therefrom away from baffle 25B.

In the non-limiting example embodiment of fig. 22A and 22B, when the baffle 25B is disposed farther from the remote heat exchanger 200C and thus increases the space therebetween, the sensor 2005A may send data to the controller 2010 that causes dampers in the remote heat exchanger 200C to direct the airflow to both sides of the zone 20C within the climate-controlled space of the transport unit 20.

23A and 23B illustrate an arrangement of a proximity sensor 2005A by which the probe end of the proximity sensor 2005A is permanently or temporarily secured to at least a bulkhead 25B; the other end of sensor 2005A is permanently or temporarily attached to the top inside zone 20 (e.g., 20B or 20C).

In the example of fig. 23B, the extendable portion of encoder-type sensor 2005A in zone 20C is a flexible wire 2305 that is connected proximate to diaphragm 25B. Accordingly, when the separator 25B moves, the flexible wire 2305 is wound or unwound using the rewinding spring. The rewind mechanism may be incorporated into a corresponding partition, such as partition 25B or remote evaporator 200C; and a cord 2305 is attached to the separator.

In the non-limiting example of fig. 23A and 23B, when sensor 2005A determines that baffle 25B is disposed in close proximity to remote heat exchanger 200C and thus reduces the space therebetween, sensor 2005A may send data to controller 2010 which causes a damper in remote heat exchanger 200C to direct the flow of air therefrom away from baffle 25B.

24A and 24B illustrate an arrangement of the proximity sensor 2005A by which the probe end of the proximity sensor 2005A is permanently or temporarily secured to at least the diaphragm 25B; the other end of sensor 2005A is permanently or temporarily attached to the top inside zone 20 (e.g., 20B or 20C).

In the example of fig. 24B, the extendable portion of encoder-type sensor 2005A in zone 20C is a flexible wire 2305 that extends relatively close to diaphragm 25B. Accordingly, when the separator 25B moves, the flexible wire 2305 is wound or unwound using the rewinding spring. The rewind mechanism may be incorporated into a corresponding partition, such as partition 25B or remote evaporator 200C; and a cord 2305 is attached to the separator.

In the non-limiting example embodiment of fig. 24A and 24B, the baffle 25B is disposed farther from the remote heat exchanger 200C, thus increasing the space therebetween, and the sensor 2005A can send data to the controller 2010 that causes dampers in the remote heat exchanger 200C to direct airflow to both sides of the zone 20C within the climate-controlled space of the transport unit 20.

The non-limiting example embodiment of fig. 25A and 25B shows an arrangement of proximity sensors 2005A by which non-contact sensors (e.g., magnets or reflectors or other sensitive materials) are secured at least in the diaphragm 25B. The sensor reader may be mounted in the insulating slot 251. As the diaphragm 25B moves, the sensor probe embedded in the diaphragm may send a signal to a corresponding sensor reader mounted in the insulated slot 251. For light sensors, a reflector 254 may be mounted in the diaphragm 25B and reflect light back to the light receiver sensor mounted therein as the diaphragm 25B moves. For induction-based systems, magnets may be mounted in spacer 25B and induction sensors may be mounted in slots 251.

In the non-limiting example of fig. 25A and 25B, when sensor 2005A determines that baffle 25B is disposed in close proximity to remote heat exchanger 200C and thus reduces the space therebetween, sensor 2005A may send data to controller 2010 which causes a damper in remote heat exchanger 200C to direct the flow of air therefrom away from baffle 25B.

26A and 26B illustrate an arrangement of the proximity sensor 2005A by which the probe end of the proximity sensor 2005A is permanently or temporarily secured to at least the diaphragm 25B; the other end of sensor 2005A is permanently or temporarily attached to the top inside zone 20 (e.g., 20B or 20C).

In the example of fig. 26B, the extendable portion of encoder-type sensor 2005A in zone 20C is a flexible wire 2305 that extends relatively close to diaphragm 25B. Accordingly, when the separator 25B moves, the flexible wire 2305 is wound or unwound using the rewinding spring. The rewind mechanism may be incorporated into a corresponding partition, such as partition 25B or remote evaporator 200C; and a cord 2305 is attached to the separator.

26A and 26B, the baffle 25B is disposed farther from the remote heat exchanger 200C, thus increasing the space therebetween, and the sensor 2005A can send data to the controller 2010 which causes dampers in the remote heat exchanger 200C to direct airflow to both sides of the zone 20C within the climate-controlled space of the transport unit 20.

Thermal sensor 2005B is described below in the context of the non-limiting example embodiment of fig. 27 and 28.

For all of the embodiments described and depicted herein, the remote heat exchanger 200B may be used to absorb heat loads from the surrounding environment, and also to absorb internal heat loads, depending on the type of cargo. Further, the surface temperatures of the bottom, side and top panels of the transport unit 20 are generally uniform, although the ambient temperature may cause any deviation.

As mentioned herein, a thermal image camera or an Infrared (IR) sensor (both denoted 2005B) may be mounted at a predetermined or calibrated location within the climate controlled space of the transport unit 20 based on the spatial arrangement within zone 10B. The thermal image camera or IR sensor 2005B may then scan the data read at fixed time intervals in the manner previously described and/or recited herein, and may calculate a three-dimensional (3D) surface temperature based on the data. Because the location of the thermal image camera or IR sensor array and the location of the remote heat exchanger 200B are fixed, zone temperature mapping may be accomplished using the location of the remote heat exchanger 200B as a reference point.

In some embodiments, the surface temperature of remote heat exchanger 200B may be lower than the surface temperature of the side walls and/or top wall of partition 25A or zone 20B; and the floor space within zone 20B may be distinguished by a partially uniform temperature gradient. Similarly, temperature data may be distinguished near the door 2700 of the transport unit 20 and wherever heat is detected entering the transport unit 20 from the surrounding environment. Thus, depending on the type of cargo, the cargo temperature can be differentiated. Thus, because the location of remote heat exchanger 200B is fixed within zone 20B, the surface temperature of any object within zone 20B may be determined and the corresponding temperature data sent from thermal sensor 2005B to controller 2010 may be used to control the volume and/or direction of the airflow from remote heat exchanger 200B.

As described and recited herein, the thermal image camera/IR sensor 2005B enables discrimination of the respective surface temperatures of the walls and floor within the climate-controlled space of the transport unit 20 and the cargo surface therein. Thus, the temperature difference between the cargo and the wall or floor can be determined and/or visualized; and the temperature difference between the return air and the cargo surface and/or floor or wall surface.

The 3D spatial map sensor 2005C is described below in the context of the non-limiting example embodiment of fig. 29.

As depicted, process flow 3000 includes sub-processes performed by various components of at least one digital camera 2900 and controller 2010. However, process flow 3000 is not limited to such components and processes, as obvious modifications may be made by reordering two or more sub-processes described herein, eliminating at least one sub-process, adding additional sub-processes, replacing components, or even letting various components assume sub-process roles consistent with other components in the following description. Process flow 300 may include various operations, functions, or actions as illustrated by one or more of 3005, 3010, 3015, 3020, 3025, 3030, and 3035. These various operations, functions or acts may, for example, correspond to software, program code or program instructions being executed by a processor, which causes the functions to be performed. Processing may begin at 3005, with reference to digital camera 2900B secured to a top plate in zone 20B and non-limiting example embodiments of digital camera 2900C secured to a top plate in zone 20C. Each digital camera may be used to estimate a volume difference in each zone, which may be due to a change in cargo volume as cargo is loaded or unloaded from the zone. In accordance with at least some embodiments, cargo levels within each of metric or english parameter measurement zones 20A, 20B, and 20C and their perimeters may be used as a baseline. The cargo level and cross-sectional area of the individual zones can also be measured in pixels.

At 3005, one or both of digital camera 2900B and digital camera 2900C may capture digital images of the interior of the respective climate controlled space. Process flow may proceed to 3010.

The controller 2010 may receive images from the respective cameras 2900 and apply relevant metrics to infer measurements or parameters of the cargo within the respective zones 20A, 20B, or 20C of the climate-controlled space. Using the inferred measurements or parameters, the controller 2010 may estimate the volumetric difference between the actual cargo and the available space and the location of such empty space, thereby controlling the airflow volume and direction from a corresponding one of the remote heat exchangers 200.

As part of the estimation process, the controller: (3010) Retrieving a corresponding image frame or pixel from the received image; (3015) applying the chrominance filter to the corresponding frame or pixel; (3020) Processing the image file in segments so that the temperature of the target area can be determined by processing segmented portions of the image using known techniques; (3025) Comparing the processed image file to stored images of the corresponding climate controlled space in various states of packaging the cargo into the transport unit 20; and (3030) estimating a current state of cargo distribution within the respective climate-controlled space. Accordingly, (3035) the controller 2010 is able to control the volume and/or direction of airflow from the remote heat exchanger 200 to an area or zone in the climate-controlled space having a temperature above a predetermined threshold.

Fig. 31 illustrates an exemplary process flow for sonar-based 3D spatial scanning in accordance with at least some embodiments of a remote vaporizer automation system as described and recited herein. Sonar-based 3D spatial scanning is described below in the context of the non-limiting example data stream of fig. 31.

The ultrasonic sensor or transducer 3100 can be disposed in any of the zones 20A, 20B, and/or 20C within the climate-controlled space of the transport unit 20 in much the same manner as the camera 2900. When instructed by a trigger signal from the controller 2010, the ultrasonic sensor 3105 may emit an acoustic signal traveling at a frequency higher than 18kHz, i.e., ultrasonic waves. When triggered, the ultrasonic sensor generates a plurality (e.g., eight) of sonic (ultrasonic) bursts and starts a timer. The timer stops when the receiver in the sensor receives a back-reflected (i.e. echo) signal. The output of the ultrasonic sensor is a high pulse of the same duration as the time difference between the transmitted ultrasonic pulse train and the received echo signal. The servo motor 3110 is a closed loop servo that uses position feedback to control its motion and final position. The input to the controller 2010 is a signal (analog or digital) representing a position commanded for the output shaft. The motor is paired with a position encoder to provide position and velocity feedback.

In an example scenario, only the location is measured. The measured output position is compared with the commanded position (external input to the controller 2010). If the output position is different from the desired position, an error signal is generated which then causes the motor to rotate in either direction as required to bring the output shaft into position. As the position approaches, the error signal decreases to zero and the motor stops.

As depicted, process flow 3200 includes sub-processes performed by at least one sensor described and/or recited herein and various components of controller 2010. However, process flow 3000 is not limited to such components and processes, as obvious modifications may be made by reordering two or more sub-processes described herein, eliminating at least one sub-process, adding additional sub-processes, replacing components, or even letting various components assume sub-process roles consistent with other components in the following description. Process flow 300 may include various operations, functions, or actions as illustrated by one or more of 3205-3300. These various operations, functions or acts may, for example, correspond to software, program code or program instructions being executed by a processor, which causes the functions to be performed.

In process flow 3200, sensor data may be acquired, for example, at fixed time intervals or when a door is open. After sensor data is acquired, a control algorithm may be initiated to control the airflow from the corresponding remote heat exchanger 200, depending on the type of sensor installed in the respective zone. If the sensor data indicates that the distance from the baffle to the corresponding remote heat exchanger 200 exceeds a predetermined threshold, the controller 2010 may vary the airflow (e.g., increase airflow speed by opening or closing one or more dampers, increase fan speed, etc.) according to the sensed cargo load or temperature within the corresponding zone. If the sensor data indicates that one side of the remote heat exchanger 200 is within a predetermined threshold distance from the corresponding bulkhead, the controller 2010 may direct the airflow in a direction opposite the bulkhead direction, wherein the airflow volume (CFM) is dependent upon the sensed cargo load or temperature within the corresponding zone. Processing may begin at 3205.

At 3205, the controller 2010 receives data from sensors corresponding to one or more of the zones 20A, 20B, or 20C of the climate-controlled space in accordance with various embodiments described and/or recited herein. The received data can include the location of the partition relative to the corresponding remote exchanger 200, and in some cases, can also include data related to spacing within the corresponding zone of the climate controlled space. Processing may proceed to 3210.

At 3210, the controller 2010 processes the received sensor data based on (i) whether the received sensor data includes a position of the bulkhead relative to the remote exchanger 200 or (ii) whether the received sensor data includes a position of the bulkhead relative to the remote exchanger 200 and data related to a distance between the cargo and a corresponding remote heat exchanger 200 within a corresponding region of the climate-controlled space. If (i), processing proceeds to 3215; if (ii), processing proceeds to 3250.

At 3215, the controller 2010 determines whether the corresponding baffle is within a threshold distance of the remote heat exchanger 200. If so, processing proceeds to 3220; if not, processing proceeds to 3225.

At 3220, the controller 2010 sends instructions to the remote heat exchanger 200 to shut down or at least substantially reduce the airflow in the direction toward the baffle. Then, the process returns to (B) 3205.

At 3225, the controller 2010 determines whether the baffle is a threshold percentage distance relative to the remote heat exchanger 200. If so, processing proceeds to 3230; if not, processing proceeds to 3235.

At 3230, the controller 2010 adjusts the airflow by a corresponding percentage in a direction toward the partition. Processing returns to (B) 3205.

At 3235, the controller 2010 determines if the corresponding baffle is more than a threshold distance from the remote heat exchanger 200. If so, processing proceeds to 3240; if not, processing returns to (B) 3205.

At 3240, the controller 2010 directs the full volume of airflow in a direction toward the baffle.

(B) 3245 indicates a return to 3205 for receiving data from the corresponding sensor.

At 3250, the controller 2010 determines if the baffle is within a threshold distance from the remote heat exchanger 200. If so, processing proceeds to 3257; if not, processing proceeds to 3255.

At 3258, the controller 2010 reduces or even shuts off the airflow in the direction of the separator.

The (a) 3255 in fig. 32A instructs a process flow to proceed with the operation shown in fig. 32B. Processing proceeds to 3260.

At 3260, the controller 2010 estimates a cargo distribution within a corresponding region of the climate controlled space and/or a temperature distribution on a side of the remote heat exchanger 200. Processing may proceed to 3265.

At 3265, the controller 2010 determines from the received sensor data whether the corresponding zone of the climate-controlled space does not include cargo or whether the temperatures on the sides of the corresponding remote heat exchanger 200 are different, e.g., whether the temperature on one side of the remote heat exchanger 200 is lower than the temperature on the other side. If so, processing proceeds to 3270. If not, processing proceeds to 3270.

At 3270, the controller 2010 sends instructions to the remote heat exchanger 200 to shut down or at least substantially reduce airflow in a direction without cargo and/or in a side direction with a determined lower temperature. Processing may return to (B) 3245.

At 3275, the controller 2010 may determine if the left side of the remote heat exchanger 200 has more cargo and/or a higher temperature than the right side. If so, processing may proceed to 3280; if not, processing may proceed to 3285.

At 3280, the controller 2010 may send instructions to the remote heat exchanger 200 to increase the airflow volume toward the left side of the remote heat exchanger 200 and decrease the airflow volume toward the right side. Processing may return to (B) 3245.

At 3285, the controller 2010 may determine if the right side of the remote heat exchanger 200 has more cargo and/or a higher temperature than the left side. If so, processing may proceed to 3290; if not, processing may proceed to 3295.

At 3290, the controller 2010 may send instructions to the remote heat exchanger 200 to increase the airflow volume toward the right side of the remote heat exchanger 200 and decrease the airflow volume toward the left side. Processing may return to (B) 3245.

At 3295, the controller 2010 may determine whether both the left and right sides of the remote heat exchanger 200 have approximately equal amounts of cargo and/or approximately equal temperatures, i.e., within a threshold amount. If so, processing may proceed to 3300; if not, processing may return to (B) 3245.

At 3300, the controller 2010 may send instructions to the remote heat exchanger 200 to equalize the airflow volumes to its left and right sides.

33A and 33B depict delivering air flow via an electrical actuator connected to a damper mechanism, i.e., air flow exhausted from the various embodiments of the remote heat exchanger 200 described and depicted herein. The air flow can be classified as follows.

One of the dampers 3305 or 3010 that is fully closed may result in unidirectional airflow from the remote heat exchanger 200; while fully open dampers 3305 and 3310 may result in multi-directional airflow.

The air flow may vary depending on the distribution of the cargo within the corresponding zone of the climate controlled space, the temperature therein, and the positioning of the baffles relative to the remote heat exchanger 200 in that zone. The opening or closing of either of dampers 3305 and 3310, respectively, may be controlled to control the airflow volume. The air flow may also be controlled based on the cargo surface temperature distribution within the corresponding region of the climate controlled space.

By continuously operating the dampers, the airflow from the remote heat exchanger 200 may rock, which may improve the airflow around the corresponding zone of the climate controlled space.

The angled airflow may be achieved by adjusting damper positioning.

From the foregoing, it will be appreciated that various embodiments of the invention have been described herein for purposes of illustration, and that various modifications may be made without deviating from the scope and spirit of the invention. The various embodiments disclosed herein are therefore not to be considered in a limiting sense, with a true scope and spirit being indicated by the following claims.
