CONSTITUTION:A space 101 between the inside of each of adsorbent-filling receptacle 100A, 100B and a solid adsorbent 120 is connected to a vapor line 810 through a four- way valve 700. A heating heat-medium circuit 200 and a cooling water circulation circuit 300 are respectively connected, in parallel, to a heat-exchanging member 110 at the inside of each of the adsorbent-filling receptacles, through directional selection valves 900 and directional selection valves 1000, which are at each side of an inlet and outlet on each of the receptacles.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an adsorption cooling device.

[Conventional technology]

For example, as shown in Fig. 7, vapor compression type cooling using fluorocarbon gas as a refrigerant and using the engine as the power source is used for cooling the interior of vehicles such as automobiles, construction machines, marine boats, etc. that are powered by internal combustion engines, and/or refrigerators. Devices are known from the prior art.

This type of vapor compression cooling system uses part of the output of the engine for running or operating purposes for cooling, which not only increases the load on the engine but also increases fuel consumption. Recently, freon has been used exclusively as a refrigerant, which has led to the issue of ozone depletion, which has led to legal regulations such as total volume control and production reductions.

Therefore, in order to solve this problem, an automobile cooler using an adsorption refrigerator that uses exhaust heat of the engine as a heat source for a heating section and does not use fluorocarbon gas has been proposed in Japanese Utility Model Application Publication No. 01-126811.

This proposal consists of an evaporator 2, an adsorbent 3 that adsorbs the refrigerant vapor generated from the evaporator 2, and evaporates the adsorbed refrigerant by heating (this can be interpreted as desorption), as shown in Figure 8. )
An adsorption refrigerator 1 is provided, which has a heating section 4 for heating the air, and a condensing section 5 for condensing 1 air from the heating section, and a heat exchanger 6 of the evaporation section 2 is connected to a cooling circuit 7 for cooling the interior of an automobile. , the heat exchangers 8 and 9 of the adsorption section 3 and the condensation section 5 are connected to a closed air cooling circuit 10, and the heat exchanger 11 of the heating section 4 is connected to an engine heat supply circuit 12. Some of the heat is used.

To explain this structure in detail, as shown in FIG. 9, the adsorption refrigerator 1 has an adsorbent tank 14 and a steam tank 15, which are connected by a steam flow path 13, while keeping both tanks sealed in a vacuum state. At 14.15, two adsorption/desorption units A and B each having a heat exchanger are installed, and the adsorbent W! 14 is filled with a silica-based solid adsorbent S that adsorbs a certain amount of a refrigerant, such as water.

Then, the heat exchanger of the adsorbent tank 14 of adsorption/desorption unit A is connected to the engine heat supply circuit 12 as the heat exchanger 11 of the heating section 4, and the steam tank 15 of adsorption/desorption unit A and the adsorption/desorption unit B are connected.
The heat exchangers in the adsorbent tank 14 are connected to the air cooling circuit IO as heat exchangers 9 and 8, respectively, to supply cooling water.

Furthermore, the heat exchanger of the steam tank 15 of the adsorption/desorption unit (B) is connected to the evaporation section 2.
It is connected to the cooling circuit 7 as a heat exchanger 6.

In this way, first, the solid adsorbent S in the adsorbent tank 14 of the adsorption/desorption unit A is heated by the supply of engine heat, and the adsorbed refrigerant moisture is evaporated while passing through the vapor flow path 13 to the heat exchanger. 9 to condense (this is called desorption by the foam applicant),
In addition, in adsorption/desorption unit) B, after completion of desorption to the adsorption/desorption unit, cold water of about 30° C. is supplied to the heat exchanger 8 of the adsorbent tank 14, and cooling water is supplied to the heat exchanger 6 of the steam tank 15. circuit 7
By passing the cold water through it, the adsorption effect of the refrigerant tea is exerted, and the refrigerant water that had been condensed in the heat exchanger 6 of the steam tank 15 is evaporated, and the latent heat at that time is used to cool the cold water in the cooling diagram B7. 8℃
Cool to a certain degree.

Here, the heat exchangers 11, 8, 9, and 6 are operated as a pair, and the adsorbent tank 14 and the steam tank 15, which are connected by the steam flow path 13, are kept sealed in a vacuum state. 14.1
A heat exchanger is installed in each unit 5, and the adsorbent [14] is filled with a silica-based solid adsorbent S that has adsorbed a certain amount of refrigerant, for example, water, and the adsorbent tanks 14 of adsorption/desorption units A and B are arranged alternately. Under heating and cooling, the corresponding tea tanks 15 are heated and cooled, respectively.
act alternately as a condenser) and an evaporator 2 (evaporator),
By constantly switching the cooling circuit to the explosion section, the latent heat accompanying the explosion of the refrigerant in the evaporation section provides effective cooling.

[Technical problem to be solved by the invention] However,
Such an adsorption refrigerator 1 requires two adsorption/desorption units A and B, each of which is formed by integrally connecting an adsorbent tank 14 and an air tank 15 through a flower passageway 13. Due to the adsorption amount characteristics of the adsorbent S, the adsorbent tank 14 requires a considerably large volume, and the required area of a heat exchanger for extracting the latent heat of evaporation also becomes considerably large.

For applications such as automobiles, where small size, light weight, low fuel consumption (high performance), and non-pollution are the criteria for determining product value, and where various devices are installed with extremely high density, low fuel consumption and non-polluting with respect to fluorocarbon gas are required. Although this proposal is excellent in this respect, there are some points that should be improved as described below.

il+ In vehicles and other low-level equipment powered by an internal combustion engine, the required temperature level and heat are insufficient during idling operation if only the exhaust heat obtained from the cooling water for cooling the engine is used.

(2) Integrating the adsorbent tank 14 and the steam tank 15 restricts the degree of freedom of attachment.

(3) It is advantageous to use the heat exchanger 22 of the cooling circuit and the evaporator 2 (steamer) of the adsorption refrigerator 1.

(4) As a convenient heat source for desorption, a high desorption temperature is preferable in order to increase the respiration rate of the solid adsorbent and increase the amount of refrigerant that contributes to evaporation, and to increase the cooling capacity. If water-based engine exhaust heat alone is insufficient, it is desirable to also use the heat held by the engine exhaust gas.

The present invention has been proposed in view of these circumstances, and provides an energy-saving and pollution-free adsorption cooling device that reduces the size of the adsorbent tank, increases the degree of freedom in installation, and increases cooling capacity. The purpose is to

The adsorption cooling device of the present invention has two adsorbent filling tanks 100A.
, 100B and the space 101 formed by the solid adsorbent 120 are connected by a single steam passage 810 via a 4-way switching valve 9°O, and each adsorbent filling tank 100A, 100B

00 and 1000, and by selectively switching the directional valve it is possible to heat one adsorbent-filled tank and cool the other.

Condenser 400, condensed liquid storage container 500. evaporator 600
is a closed circulation system forming means 800 and a four-way switching valve 700 from the empty space of one adsorbent filling tank to the empty space of the other adsorbent filling tank.
By switching the four-way switching valve 700, the adsorbate vapor desorbed (or released) from the adsorbent-filled tank in the desorption process is directed to the adsorbent-filled tank in the adsorption process. supplies steam to steam passage 810 in one direction.

will be established. The load of the evaporator 600 is, for example, duct) 611
This is the air inside the vehicle that is sent by the blower 612 via the air blower 612. Naturally, drain is generated with cooling, so this is used to cool the air cooler 310 and/or condenser 400, that is, the cooling water circulation circuit 300, to improve performance. Plan. In addition, 4
The direction switching valve 700 and the direction switching valve 900.1000 may be two-way valves as shown in FIG.

According to such a device, the following actions are performed.

ia) Adsorption properties of solid adsorbents and vapor transfer When a gas and a solid come into contact, molecules disappear from the gas phase, and when the molecules enter the solid, they adsorb and accumulate on the surface. Adsorption
If desorption is defined as the return of adsorbed molecules to the gas phase, then adsorption can be said to be a phenomenon in which the concentration of one phase differs from the concentration inside the phase at the interface where two phases meet. In this case, the substance whose concentration has changed is adsorbed by the other substance, and it is generally known that the adsorbing substance is called an adsorbent, and the adsorbed substance is called an adsorbate.

The amount of adsorbate per unit weight of adsorbent is adsorption amount (CCat
O℃, 1ate/g, Mol/g, I1g/g
), and may also be defined in weight percent.

Adsorption phenomena can be broadly classified into physical adsorption and chemisorption. Physical adsorption is mainly based on van der Waals forces that act between adsorbent and adsorbate molecules.
This is a reversible phenomenon in which heat of adsorption is released during adsorption and is called molecular adsorption.

Chemical adsorption is considered to be a binding phenomenon between adsorbent and adsorbate molecules mainly based on valence force, and is an irreversible phenomenon.

The amount of adsorption varies greatly depending on the combination of adsorbent and adsorbate, but once that combination is specified, the amount of adsorption q is determined as a function of pressure P and temperature T.

That is, q = q (P, T) (11 The amount of adsorption when the temperature is constant is a function only of pressure, and if this is qt, then Qt - Qt (P) [21, which is called the occlusal isobaseline.

If the amount of adsorption when the pressure is constant is q2, this is expressed as Qp - Ql (T) +31, which can be determined by measuring the adsorption isobase line at each temperature. Further, at this time, a characteristic in which the amount of adsorption is constant, which is called an isosorption amount line, can be found as P=q, (T) 14>.

The adsorption isotherms when water acting as a refrigerant is used as the adsorbent and the adsorbent is (a) JIS A type silica gel (b) Molecular Sib 13X (c) Molecular Sib 4X are shown in Figures 3 and 4, respectively. As shown in FIG.

For example, in the case of JIS A-type silica gel and water, as shown in Figure 3, when the water vapor partial pressure is 42.2 wHg (equivalent saturation temperature 35°C) and the adsorbent temperature is 85°C, the water vapor partial pressure is q1, S = 5%, water vapor partial pressure 6 .5mHg (equivalent saturation temperature 5°C) and adsorption temperature 35°C, qta3s=9%, showing different adsorption amounts.

As mentioned above, this change is a reversible change, so if the temperature of the adsorbent and the corresponding pressure of the adsorbent are selected appropriately, it is possible to put in and take out a predetermined amount of adsorbent. Amount of change (also expressed as respiration rate) Δ
q is 4%, that is, 40 g of moisture is transferred per IKg of adsorbent.

In the present invention, two containers filled with an adsorbent and an adsorbate are provided, and the above two levels of pressure and temperature at the interface between the adsorbent and adsorbate in each container are maintained at the higher level during the desorption process. By selectively switching the other to a lower level adsorption process, the vapor released from one vessel (or the adsorbent in the vessel) undergoing the desorption process is transferred to the other vessel (or the adsorbent within the vessel) undergoing the adsorption process. The other container (or the adsorbent in the container) acts like a kind of suction pump. Since the transfer of adsorbate to and from the container proceeds in the gas phase, in order to ensure that this process proceeds smoothly, that is, to ensure uniform contact of the adsorbate with the adsorbent and its separation from the adsorbent, there is a A cavity is provided as a passage for adsorbate 1, and vapor is transferred through a flow path connected to this cavity.

(bl) Supply of heat to the adsorbent interface and removal In order to raise and lower the temperature of the adsorbent, a heat source for heating and a cooling source for cooling are required. The heat exchange member 110 is provided so that the adsorbent covers the surface of the heat exchange member 110, and has a heat medium passage built therein and communicates with the outside via heat medium supply ports 131A and 131B.

This outside is filled with an adsorbent tank 100A.

By connecting to a pair of directional switching valves 900 and 1000 selectively connected in parallel to the cooling water circulation circuit 300, the high temperature liquid heating medium circuit 200 which is a heating source and the air cooler 310 which is a cooling source are connected. A cooling water circulation circuit 300 having
As a result, desorption progresses at the interface of one adsorbent and adsorption progresses at the interface of the other adsorbent.

tel Condensation of adsorbate vapor, evaporative desorption, and mere movement of adsorbate vapor due to adsorption do not cause a thermodynamic cooling effect, so in order to extract the latent heat of adsorbate, it is necessary to cool the adsorbate vapor obtained by desorption and then After condensation, a step of evaporating it is essential.

In the present invention, this desorption vapor is condensed in a condenser 400 cooled by a cooling water circulation circuit 300 having an air cooler 310.
The liquefied adsorbate condensed in the avM device 40'0 is evaporated in the evaporator 600 to remove heat from the desired medium.
In other words, the cooling effect is taken out.

At this time, the pressures of the condenser 400 and the evaporator 600 are operating variables, from the relationship of vapor-liquid equilibrium, for example, 42.2 m Hg if the condensing temperature is 35°C.

If the evaporation temperature is 5° C., it will be 6.5 days of Hg, and the condenser 400 and evaporator 600 are designed to satisfy this condition involving exchange of heat.

Switching of the steam flow path Inside the two adsorbent filling tanks are two 2i! four-way switching valves 700! The other two 2it paths of the flow paths of the four-way switching valve 700 communicate through the L path, from the − side toward the other side,
The condenser 400, liquid storage container 500, and evaporator 600 are connected in this order in a closed circulation system forming means 800 to form a single vapor flow path.

These form a single vapor flow path.

While the two adsorbent-filled tanks alternately repeat desorption and adsorption, the empty space in the adsorbent-filled tank in the desorption example is always on the condensation n 400 population side, and the empty space in the adsorbent-filled tank on the adsorption side is always on the condensation side. is connected to the outlet side of the ignition device 600 to generate a one-way brown air flow.

tel Suppression of vapor flow rate fluctuations due to switching between desorption and adsorption The liquid storage application 8500 is a buffer that suppresses vapor flow fluctuations in the vapor flow path when switching alternately between desorption and adsorption in two adsorbent-filled tanks. perform an action.

(f) Cooling effect The adsorbate liquefied in the condenser 400 is self-cooled to its pressure saturation temperature at the inlet of the evaporator 600, and then evaporates by taking heat from the medium that is the cooling load.

For example, when the evaporation pressure saturation temperature is 5°C, the latent heat of vaporization of water is 594. 6Kca
Since it is k /b, a cooling effect of 23.8 Kcal is obtained per unit weight (1 pupil) adsorption rate.

(g) Exhaust heat recovery from internal combustion engines The cooling water circulation circuit 210 cools internal combustion engines used in vehicles powered by internal combustion engines, such as automobiles and marine boats, or in equipment equipped with diesel generators, etc. This is done by circulating cooling water around the engine's cylinders.

An exhaust heat exchanger 220 is connected in series or parallel to this cooling water circulation circuit 210 to recover engine exhaust heat and recover a predetermined amount of heat at a higher temperature than that recovered in the conventional cooling water circulation circuit 210. This increases the desorption temperature of the adsorbent, increases the respiration rate of the adsorbate, thereby increasing the amount of steam generated per unit weight of adsorbent, and enhancing the cooling effect.

Furthermore, while obtaining the same cooling effect, the adsorbent filling tank can be made smaller and lighter with less consideration.

Although the cooling load of a vehicle varies depending on the type of vehicle, driving conditions, and weather conditions, the following examples are given. That is, in the case of a passenger car with a displacement of 2000 cc, assuming that the outside air temperature is 35° C. and the interior temperature is 25° C., the vehicle speed is 40 km/h and the running special rate is 3500 Kcal/h, and the idling time is approximately 2500 Kcal/h.

On the other hand, if we pay particular attention to idling, the amount of heat dissipated by the radiator in the existing cooling water system is approximately 2600 K.
ca! It is estimated that /h.

Considering that the coefficient of performance of this type of cooling device is 0.5 to 0.7, it can be seen that the amount of heat contributing to cooling is insufficient compared to the amount of heat used for heating.

Here, if the amount of heat held by the exhaust gas is recovered to the extent of 200, the total amount of heat recovered from the internal combustion engine is approximately 4.
It is estimated to be 500 Kcal/h, which is enough heat to cover the cooling load.

Heat can be calculated in the same way under running conditions, and exhaust heat recovery is necessary.

(h) Since air containing water vapor acts on the air cooler and/or the condensing capacity increasing evaporator 600 as a cooling load,
The saturated partial pressure of water vapor in the air cooled by the evaporator decreases, and excess water vapor is separated as a drain 601. If this cooled drain 601 is used to cool the air cooler 310 of the cooling water circulation circuit 300 and/or the condenser 400 cooled by the cooling water circulation port 8300, it will help prevent loss of cold heat and increase the capacity of the air cooler and/or condensation. .

(i) Selection of adsorbent Once the adsorbate has been determined, and the adsorption temperature, desorption temperature, evaporation pressure, and condensation pressure have been determined, the selection of adsorbent becomes a factor that controls the cooling capacity per unit weight of the adsorption cooler. .

Adsorbate is water, adsorption temperature/desorption temperature -35785℃
Evaporation temperature saturation pressure / condensation temperature saturation pressure = 6.5 /
42.2 tm against Hg! ! ! The amount of respiration of the fish is as follows: (a) 4.0% (b) 3.2% (c) 25% (
d) 1.5°% However, (a) JISA type silica silica gel activated alumina (c) Zeolite 4A (d) Zeolite 13X, and JISA type silica gel to activated alumina with granular pores on the order of 100 to 1000 yen is suitable as an adsorbent. . - According to such a device, the following effects can be achieved.

(11 Adsorbent tank 14 (Fig. 9) and condensate tank 15 (Fig. 9)
Since they are configured separately from each other, their installation is quite flexible.

(2) The structure is simplified by using the heat exchanger 22 (FIG. 9) of the cooling circuit and the smoke generator 2 (evaporator) (FIG. 9) of the adsorption refrigerator 1.

(3) As a heat source for desorption, in order to increase the respiration rate of the unique adsorbent and increase the amount of refrigerant that contributes to explosions, and to increase the cooling capacity, it is preferable that the desorption temperature is high. When the exhaust heat from the engine is insufficient, the heat held in the exhaust gas from the engine is also used to contribute to an increase in the amount of adsorbate respiration, improving the cooling capacity per unit weight of the cooling device.

(4) The tea air flow path is unique and has an extremely simple configuration for this type of cooling device, which greatly contributes to miniaturization and weight reduction, and can also be expected to increase reliability due to the extremely simple configuration. .

(51) Due to the weight reduction and no need for engine power, the transportation power of the vehicle is reduced and fuel efficiency is improved.

(6) Since cooling capacity can be extracted without using fluorocarbon-based refrigerants, it greatly contributes to preventing ozone layer depletion.

〔Effect of the invention〕

In short, according to the invention set forth in item 1, an energy-saving and pollution-free adsorption cooling device is obtained which reduces the size of the suction tank, increases the degree of freedom in mounting arrangement, and increases the cooling capacity.

According to the invention set forth in Item 2, by increasing the amount of exhaust heat recovered from the internal combustion engine, the desorption temperature of the endothermic agent is increased, and the respiration rate of the adsorbed amount is increased, thereby reducing the amount of brown fumes generated per unit weight of the adsorbent. The cooling effect can be increased, and the amount of adsorbent packed can be reduced in size and weight.

According to the invention of item 3, by using the condensed water of the evaporator to cool the air cooler of the cooling water circulation circuit and/or the condenser cooled by the cooling water circulation circuit, loss of cold heat can be prevented and the air cooler and/or It is possible to increase the capacity of the condenser.

According to the fourth aspect of the invention, it has been found that JIS-A type silica gel or activated alumina is suitable as the adsorbent.
