Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, the use of directional terms such as "inner" and "outer" means both the inner and outer of the profile of the corresponding component or structure, unless otherwise specified; the terms "upstream" and "downstream" and "inlet and outlet" refer to the flow direction of the refrigerant, specifically, the flow direction toward the refrigerant is downstream, the flow direction away from the refrigerant is upstream, the opening through which the fluid flows into components such as a condenser and a bypass line is the "inlet", and the opening through which the fluid flows out of components such as a condenser and a bypass line is the "outlet". Furthermore, terms such as "first," "second," and the like, are used herein to distinguish one element from another, and are not necessarily sequential or significant.

As shown in fig. 1 to 4, the embodiment of the present disclosure provides a condenser applied to an air conditioning system, wherein the condenser includes a condenser body, the condenser body includes a first refrigerant flow path 1 extending therein, a first end 11 of the first refrigerant flow path 1 forms an inlet 4 of the condenser, a second end 12 forms an outlet 5 of the condenser, the condenser body is further provided with a second refrigerant flow path 2, a first end 21 of the second refrigerant flow path 2 is connected to the first refrigerant flow path 1 in a bypassing manner and is selectively conducted, and the second end 22 is merged with the outlet 5 of the condenser.

In the technical scheme of the embodiment of the disclosure, the condenser comprises a condenser body, a pipeline forming the first refrigerant flow path 1 is arranged in the condenser body, and a heat dissipation device in the condenser body enables a high-temperature and high-pressure gaseous refrigerant flowing through the first refrigerant flow path 1 to generate phase change and be condensed into a high-temperature and high-pressure liquid refrigerant. The condenser of the embodiment of the present disclosure further includes a second refrigerant flow path 2 disposed outside the condenser body, the second refrigerant flow path 2 is a bypass pipe mainly used for guiding out the liquid refrigerant inside the condenser body, and since the second refrigerant flow path 2 is located outside the condenser body, the refrigerant does not undergo a condensation process in the second refrigerant flow path 2, and therefore, the flow length of the refrigerant flowing through the first refrigerant flow path 1 inside the condenser body can be shortened through the second refrigerant flow path 2 located outside the condenser body, thereby changing the working capacity of the condenser. The working capacity of the condenser mentioned in the embodiments of the present disclosure may be represented by a flow length of the first refrigerant flow path 1, where the flow length refers to a length of a path through which the refrigerant flows in the first refrigerant flow path 1.

Based on above-mentioned technical scheme, the condenser that this disclosure provided can have two kinds of circulation routes. Firstly, when the second refrigerant flow path 2 is disconnected from the first refrigerant flow path 1, a refrigerant flows in from an inlet 4 of the condenser and then flows out from an outlet 5 of the condenser along the first refrigerant flow path 1, at the moment, the refrigerant flows through the whole course of the first refrigerant flow path 1, a heat dissipation device in the condenser body condenses the refrigerant in the whole course, and the condenser in the circulation path has the maximum working capacity; secondly, when the second refrigerant flow path 2 is communicated with the first refrigerant flow path 1, the refrigerant can flow in from the inlet 4 of the condenser, firstly flows to the joint with the second refrigerant flow path 2 along the first refrigerant flow path 1, and then directly flows to the outlet 5 of the condenser from the second refrigerant flow path 2, at this time, the refrigerant only flows through the upstream path of the joint in the first refrigerant flow path 1, the flow length is less than the whole course of the first refrigerant flow path 1, and the refrigerant is only condensed within the flow length, and the liquid refrigerant after phase change can enter the circulation pipeline of the air conditioning system through the second refrigerant flow path, so the flow length of the refrigerant in the condenser body is necessarily shortened, and therefore, the condenser in the circulation path has relatively small working capacity.

It can be seen that the second refrigerant flow path 2 can change the flow length of the refrigerant in the condenser body, so that the condenser has different working capacities, i.e. the amount of the gaseous refrigerant condensed in the condenser body can be adjusted to meet different condensation demands, thus improving the working power of the condenser, avoiding the condenser being always in a high-power working state, not only reducing the energy consumption, but also prolonging the service life of the condenser. In addition, when needing to give indoor cooling, can close second refrigerant flow path 2 earlier, make the condenser operate with maximum working capacity, in order to realize rapid cooling's effect, after the cooling is accomplished, when needing to maintain the constant temperature state, switch on second refrigerant flow path 2 again, make the condenser operate with less working capacity, fluctuate with slowing down the indoor temperature, improve the body and feel the travelling comfort, can avoid frequently opening and closing the fixed displacement compressor on the one hand like this, improve the life of compressor, on the other hand can make the variable displacement compressor adjust to the energy-conserving mode of preferred according to the working capacity adaptability of condenser, be favorable to practicing thrift air conditioning system's whole energy consumption.

As an exemplary embodiment of the disclosure, as shown in fig. 1, the condenser may further include a third refrigerant flow path 3 disposed outside the condenser body, a first end 31 of the third refrigerant flow path 3 is connected to the first refrigerant flow path 1 and located upstream of the first end 21 of the second refrigerant flow path 2, and is selectively communicated with the first refrigerant flow path 1, and a second end 22 is connected to the first refrigerant flow path 1 and located downstream of the first end 21 of the second refrigerant flow path 2.

Like the second refrigerant flow path 2, the third refrigerant flow path 3 is also a bypass pipe for mainly guiding out the liquid refrigerant inside the condenser body, the condensation process does not occur in the third refrigerant flow path 3, so the flow path length of the first refrigerant flow path 1 can be changed by adding the third refrigerant flow path 3, that is, in addition to the above-mentioned two flow paths, the condenser in the embodiment of the present disclosure can also have a third flow path, that is, after the refrigerant flows into the inlet 4 of the condenser, the refrigerant first reaches the junction with the third refrigerant flow path 3 along the first refrigerant flow path 1, the refrigerant can flow into the first end 31 of the third refrigerant flow path 3, and then flows out of the second end 32 of the third refrigerant flow path 3 to enter the first refrigerant flow path 1 again, and the incompletely condensed refrigerant is condensed again and then flows out of the outlet 5 of the condenser to the air conditioning circulation pipeline.

By additionally arranging the third refrigerant flow path 3, the diversity of the working capacity of the condenser in the embodiment of the present disclosure is increased, and similarly, in other embodiments of the present disclosure, a plurality of refrigerant flow paths other than the second refrigerant flow path 2 and the third refrigerant flow path 3 may be further provided outside the condenser body, and the present disclosure is not limited to the two bypass refrigerant flow paths.

As an alternative embodiment of the present disclosure, the refrigerants used in the first refrigerant flow path 1, the second refrigerant flow path 2 and the third refrigerant flow path 3 may be R134A, R1234YF, R410A, etc., but are not limited thereto.

In order to realize selective conduction among the refrigerant flow paths and control the flow paths of the refrigerant in the condenser body, at least one valve may be disposed in each refrigerant flow path for controlling the opening and closing of each flow path, wherein the valve may be a manually controlled switch valve or an electrically controlled solenoid valve, and the disclosure is not limited thereto. In addition, in the embodiment of the present disclosure, the control of the valve may be performed wirelessly, wiredly, etc., and may be designed by those skilled in the art as needed.

As an exemplary embodiment of the present disclosure, a specific structure of the condenser will be described in detail below with reference to fig. 1 to 4. As shown in fig. 1, the condenser includes a first header 13, a second header 14, and a plurality of micro-channel pipes 15, which form a first refrigerant flow path 1, the first header 13 and the second header 14 are respectively disposed at two ends of the plurality of micro-channel pipes 15 and are communicated with the micro-channel pipes 15, the plurality of micro-channel pipes 15 are sequentially disposed along an extending direction of the first header 13 and the second header 14, that is, an axis of the first header 13 and an axis of the second header 14 are perpendicular to an axis of the micro-channel pipes 15, a plurality of partition plates 16 may be further disposed in the first header 13 and the second header 14, the partition plates 16 are located in the middle of adjacent micro-channel pipes 15, and the partition plates 16 in the first header 13 and the partition plates 16 in the second header 14 are arranged in a staggered manner along the extending direction of the first header 13 and the second header 14. Thus, not only can the first refrigerant flow path 1 be formed by meandering in the condenser main body, but also the space occupied by the first refrigerant flow path 1 can be reduced.

Further, the inlet 4 of the condenser is formed at the first end 131 of the first collecting pipe 13, the outlet 5 of the condenser is formed at the second end 132 of the first collecting pipe 13, the second refrigerant flow path 2 is connected to the first collecting pipe 13, and the third refrigerant flow path 3 is connected to the second collecting pipe 14. Since the second refrigerant flow path 2 and the third refrigerant flow path 3 do not condense, in order to save cost and reduce the occupied space of the condenser, the second refrigerant flow path 2 and the third refrigerant flow path 3 are designed to be short enough as much as possible, that is, the second refrigerant flow path 2 is extended close to and parallel to the first collecting pipe 13 as much as possible after being bypassed from the first collecting pipe 13, and then is merged with the outlet 5 of the condenser, and similarly, the third refrigerant flow path 3 is also extended close to and parallel to the second collecting pipe 14 as much as possible after being bypassed from the second collecting pipe 14.

Specifically, as shown in fig. 1, the number of the microchannel pipes 15 is four, two baffles 16 are provided in the first header 13 to divide the first header 13 into three chambers, and one baffle 16 is provided in the second header 14 to divide the second header 14 into two chambers, so that the first refrigerant flow path 1 is formed in a meandering manner as a first flow path 101, a second flow path 102, a third flow path 103, and a fourth flow path 104, which are connected in this order. Wherein, each flow includes one microchannel pipeline 15, and the cross-sectional area of each microchannel pipeline 15 is different, for example, from the first flow 101 to the fourth flow 104, the cross-sectional area of the microchannel pipeline 15 may be decreased in sequence. However, the present disclosure is not limited thereto, and in other alternative embodiments of the present disclosure, the microchannel tubes 15 having different cross-sectional areas may be arranged arbitrarily, and the microchannel tubes 15 having the same cross-sectional area may be provided in four flow paths.

In this way, the first end 21 of the second refrigerant flow path 2 may be correspondingly connected to the middle chamber of the first header 13, that is, the inlet of the second refrigerant flow path 2 is selectively communicated with the outlet of the second flow path 102, and both ends of the third refrigerant flow path 3 may be respectively connected to two chambers of the second header 14, that is, the inlet of the third refrigerant flow path 3 is selectively communicated with the outlet of the first flow path 101, and the outlet of the third refrigerant flow path 3 is communicated with the inlet of the fourth flow path 104.

In order to control the opening and closing of each flow path, as shown in fig. 1, the condenser according to the embodiment of the present disclosure further includes a first valve 6, a second valve 7, a third valve 8, and a fourth valve 9, where the first valve 6 is disposed between the second flow path 102 and the third flow path 103 to control the flow path length of the first refrigerant flow path 1, the second valve 7 is disposed in the second refrigerant flow path 2 to control the opening and closing of the second refrigerant flow path 2, the third valve 8 is disposed in the third refrigerant flow path 3 to control the opening and closing of the third refrigerant flow path 3, and the fourth valve 9 is disposed at an outlet of the fourth flow path 104 to prevent the refrigerant flowing out from the second refrigerant flow path 2 from flowing into the fourth flow path 104 again, where the fourth valve 9 may be a block valve or a one-way valve, but is not limited thereto.

According to the specific structure of the condenser provided by the embodiment of the present disclosure, with reference to fig. 1 to 4, the condenser has the following operation modes:

in the first operation mode, as shown in fig. 1, the second valve 7 and the third valve 8 are closed, and the first valve 6 and the fourth valve 9 are opened, where the refrigerant flow path is: the inlet 4 of the condenser → the first header 13 → the first flow path 101 → the second header 14 → the second flow path 102 → the first header 13 → the third flow path 103 → the second header 14 → the fourth flow path 104 → the outlet 5 of the condenser; under the working mode, the four processes of the condenser are all in a working state, namely, the working capacity of the condenser reaches the maximum, and other components in the air conditioning system are matched to rapidly cool the indoor space.

In the second operation mode, as shown in fig. 2, the first valve 6, the third valve 8, and the fourth valve 9 are closed, and the second valve 7 is opened, where the refrigerant flow path is: the inlet 4 of the condenser → the first header 13 → the first flow path 101 → the second header 14 → the second flow path 102 → the first header 13 → the second refrigerant flow path 2 → the outlet 5 of the condenser; in this operation mode, the first flow path 101 and the second flow path 102 of the condenser are in an operation state, and the operation capacity of the second operation mode is reduced compared with the first operation mode, and under the condition that the external temperature is not high or only the room temperature needs to be maintained, the selection of the operation mode is beneficial to reducing the overall energy consumption of the air conditioning system.

In the third operation mode, as shown in fig. 3, the first valve 6 is closed, and the second valve 7, the third valve 8 and the fourth valve 9 are opened, where the flow paths of the refrigerant are: an inlet 4 of the condenser → the first header 13 → the first flow path 101 → the second header 14, and the flow division starts at the second header 14, and a part of the refrigerant flows through the second flow path 102 → the first header 13 → the second refrigerant flow path 2 → an outlet 5 of the condenser, and another part of the refrigerant flows through the third refrigerant flow path 3 → the fourth flow path 104 → the outlet 5 of the condenser; at this time, the first flow 101, the second flow 102, and the fourth flow 104 of the condenser are all in the operating state, and therefore, the operating capacity of the condenser in the third operating mode is larger than that in the second operating mode.

In the fourth operation mode, as shown in fig. 4, the first valve 6 and the second valve 7 are closed, and the third valve 8 and the fourth valve 9 are opened, where the flow paths of the refrigerant are: the inlet 4 of the condenser → the first header 13 → the first flow path 101 → the second header 14 → the third refrigerant flow path 3 → the fourth flow path 104 → the outlet 5 of the condenser; at this time, the first process 101 and the fourth process 104 are in the working state, and although there are two processes in the working state as in the working mode two, when the cross-sectional areas of the microchannel pipes 15 corresponding to each process are different, for example, from the first process 101 to the fourth process 104, the cross-sectional areas of the microchannel pipes 15 may be sequentially reduced, and the working capacity of the condenser in the working mode four is smaller than that in the working mode two.

Another embodiment of the present disclosure also provides an air conditioner including the condenser as described above. In order to facilitate users to adjust the capacity of the condenser more conveniently, buttons or menu options corresponding to a plurality of working modes of the condenser respectively can be additionally arranged on an air conditioner panel or an air conditioner remote controller.
