[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adsorption type refrigerating apparatus provided with an adsorbing / desorbing device for adsorbing / desorbing refrigerant vapor, and particularly, to shorten the length of a pipeline through which the refrigerant vapor flows. Regarding things.

[0002]

2. Description of the Related Art An adsorption refrigeration system includes an adsorber / desorber containing an adsorbent for adsorbing / desorbing refrigerant vapor, a condenser for condensing the refrigerant vapor desorbed from the adsorber / desorber, and a condenser for condensing the refrigerant. It is composed of an evaporator for evaporating the refrigerant liquid condensed in the refrigerator, and recently, it has been considered to use this adsorption type refrigeration system in a vehicle air conditioner.

When the adsorption type refrigeration system is used in a vehicle air conditioner, an evaporator for cooling the vehicle compartment is arranged in the front part of the vehicle compartment, for example, in a dashboard provided in front of the driver's seat and the passenger seat. To be done. Also, the intake / desorption device and the condenser are installed in the engine room, but the condenser adopts a configuration in which it is cooled by the air taken into the engine room from the outside of the vehicle. It is located in the front of the engine compartment. Therefore, the condenser is arranged in the front of the engine room, the evaporator is arranged in the front of the passenger compartment, and the intake / desorption devices are arranged in the engine room such that they are located between the condenser and the evaporator. It will be.

[0004]

In the adsorption type refrigeration system,
Refrigerant vapor desorbed in the adsorber / desorber is condensed in the condenser and liquefied, and the refrigerant liquid evaporates in the evaporator and is returned to the adsorber / desorber, so the adsorber / desorber and the condenser are connected. Refrigerant vapor flows through the pipeline and the pipeline connecting the evaporator and the adsorption / desorption device.

Since the refrigerant liquid has a small volume per unit weight (hereinafter, specific volume), the pipeline through which the refrigerant flows in a liquid state may be constituted by a pipe having a small diameter, but the refrigerant vapor has a large specific volume. If the pipeline in which the refrigerant flows as vapor is composed of a small-diameter pipe, the flow velocity of the refrigerant vapor in the pipeline becomes extremely high, resulting in a large pressure loss.

Therefore, a pipeline through which the refrigerant flows as vapor,
That is, the pipes connecting the adsorption / desorption device and the condenser and the pipes connecting the evaporator and the adsorption / desorption device have a large diameter in order to reduce the flow velocity and reduce the pressure loss. You need to use different pipes. However, when using a large diameter pipe, it is necessary to place the condenser in the front part of the engine room and the evaporator in the front part of the vehicle compartment. However, the large-diameter pipe is drawn around the engine room for a long time back and forth, which is disadvantageous in terms of space, and the length of the pipeline through which the refrigerant becomes vapor becomes long as a whole, resulting in pressure loss. This causes a problem that the reduction effect is lacking.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a desorption type refrigerating apparatus which can shorten the length of a pipeline through which a refrigerant becomes vapor.

[0008]

In order to achieve the above object, the present invention provides an adsorbent / desorber containing an adsorbent that adsorbs / desorbs refrigerant vapor, and a refrigerant desorbed from the adsorber / desorber. In an adsorption type refrigerating apparatus comprising a condenser for condensing vapor and an evaporator for evaporating a refrigerant liquid condensed by the condenser, a heat exchanger connected to the condenser or the evaporator via a circulation path. Is provided and the refrigerant liquid is circulated between the condenser or the evaporator and the heat exchanger (Claim 1).

In this case, the heat exchanger can be connected to the condenser (claim 2), and the heat exchanger can also be connected to the evaporator (claim 3).

[0010]

In the adsorption type refrigerating apparatus of the present invention constructed as described above, the refrigerant liquid in the condenser or the evaporator flows into the heat exchanger through the circulation path, and the heat of the external After exchanging heat with a cold heat source or a high heat source, it returns to a condenser or an evaporator. The refrigerant liquid returning from the heat exchanger to the condenser or evaporator is cooled or heated by the external cold heat source or the high heat source in the heat exchanger, and therefore, the refrigerant vapor is cooled in the condenser for condensation. After the temperature rises or the vaporizer evaporates to a low temperature, it again flows into the heat exchanger and exchanges heat with an external cold heat source or a high heat source.

As described above, since the condenser or the evaporator exchanges heat with the external cold heat source or the high heat source through the heat exchanger, the condenser or the evaporator is located at a position away from the cold heat source or the high heat source. Therefore, it is possible to dispose the adsorption / desorption device, the condenser, and the evaporator close to each other. Moreover, since the liquid state refrigerant flows as the heat exchange medium in the circulation path connecting the condenser or the evaporator and the heat exchanger, the circulation path can be configured by a pipe having a small diameter.

[0012] From the above, even if a heat exchanger is provided, since the refrigerant flows as vapor, it is necessary to increase the diameter of the pipe as a pipe connecting the adsorption / desorption device and the condenser. It is possible to stop only in the lines and in the lines connecting the evaporator and the adsorber / desorber, and therefore by placing the adsorber / desorber, the condenser and the evaporator close to each other, the refrigerant vapors The length of the flowing pipeline can be shortened, space can be saved, and pressure loss can be reduced.
Moreover, since heat exchange between the condenser or the evaporator and the heat exchanger is performed by sending and returning the condenser or the refrigerant liquid accumulated inside the condenser to the heat exchanger,
High heat exchange efficiency can be obtained.

In the adsorption type refrigerating apparatus according to the second aspect of the present invention, since the heat exchanger is connected to the condenser, even if the position where the evaporator is arranged is restricted due to the relationship with the high heat source, the adsorbing / desorbing device. By arranging the condenser close to the evaporator, the pipeline through which the refrigerant vapor flows can be shortened. In the adsorption refrigerating apparatus according to claim 3, the heat exchanger is connected to the evaporator, so that even if the position where the condenser is arranged is restricted due to the relationship with the cold heat source, the adsorber / desorber and the evaporator. Is arranged close to the condenser, it is possible to shorten the pipeline through which the refrigerant vapor flows.

The refrigerant vapor desorbed from the refrigerant flows out from the outflow pipes 23 and 24. The outlet 25c of the three-way switching valve 25 is connected to the inlet 26a of the condenser 26 via the intermediate pipe 27, and the outlet 26b of the condenser 26 is passed through the intermediate pipe 28, the pressure reducer 29, and the intermediate pipe 30 in this order.

33c is connected to the other ends of the first and second suction / desorption devices 1 and 2 via return pipes 34 and 35.

The evaporator 31 is in the shape of a container, and one end side of a forward path side pipe 36 and one end side of a return path side pipe 37 forming a circulation path are connected to the bottom side and the upper side thereof. The other ends of the outward pipe 36 and the return pipe 37 are connected to an inlet 38 a and an outlet 38 b of the heat exchanger 38. A circulation pump 39 is provided in the middle of the outward pipe 36,
When the circulation pump 39 is activated, the refrigerant liquid in the evaporator 31 circulates between the evaporator 31 and the heat exchanger 38.

The outside air, which is a cold heat source, is blown to the condenser 26 by a blower fan 40 for radiator of engine cooling water, and the refrigerant vapor flowing into the condenser 26 is It exchanges heat with this outside air and is cooled and condensed. The heat exchanger 38 exchanges heat with the fluid to be cooled, which is a high heat source, that is, the air blown into the vehicle interior by the blower fan 41 to cool the air.
It is designed to cool the passenger compartment.

When the adsorption type refrigerating apparatus as described above is mounted on an automobile, as shown in FIG. 2, for example, the first and second adsorbing / desorbing units 1, 2, the condenser 26 and the evaporator 31 are the engine. The heat exchanger 38 is arranged in the room 42, and the heat exchanger 38 is installed in the passenger compartment 43.
It is arranged in a dashboard 45 provided in front of the driver's seat and the front passenger's seat, which is a rear side of a dash lower panel 44 that partitions the engine room 42 from the vehicle compartment 43. Here, the condenser 26 is arranged in the front part of the engine room 42 in order to improve the heat exchange performance with the outside air blown by the blower fan 40 of the radiator, and the first and second adsorbing / desorbing devices 1 are provided. , 2 and the evaporator 31 are arranged as close to the rear side of the condenser 26 as possible.

Next, the operation of the above configuration will be described. Now, it is assumed that the engine has finished warming up and the temperature of its cooling water is sufficiently high. Further, the adsorbent 3 of the first adsorption / desorption device 1 is in the adsorption state in which the refrigerant vapor is adsorbed, and the adsorbent 4 of the second adsorption / desorption device 2 is in the desorption state in which the refrigerant vapor is not adsorbed. And

When the cooling operation of the air conditioner is started in this state, the heating fluid and cooling fluid supply pumps (not shown) are activated, and the three-way switching valves 8, 12, 17, 20, 2 are selected.
5, 33 are switched as shown by the solid line in FIG. 1, and the circulation pump 39 and the blower fan 41 are activated (the blower fan 40 is already operated for cooling the engine cooling water).

Now, the three-way switching valves 8, 12, 17, shown in FIG.
The switching state of 20, 25, 33 is such that the first suction / desorption device 1 is on the desorption side and the second adsorption / desorption device 2 is on the adsorption side, and the heating fluid is the supply pipe 7 and the three-way switching valve. 8, first
The heat exchange pipe 5 of the suction / desorption device 1 is discharged from the discharge pipe 21 through the three-way switching valve 17, and the cooling fluid is heat exchanged between the supply pipe 11, the three-way switching valve 12, and the first suction / desorption device 1. Exhaust pipe 22 through pipe 6 and three-way switching valve 20
Emitted from.

The adsorbent 3 in the first adsorption / desorption device 1 is heated by the heating fluid flowing through the heat exchange pipe 5,
This causes the desorption action to desorb the adsorbed refrigerant vapor. The refrigerant vapor desorbed from the adsorbent 3 flows into the condenser 26 through the outflow pipe 23, the three-way switching valve 25, and the intermediate pipe 27 in this order, and exchanges heat with the air outside the vehicle blown by the blower fan 40 to be condensed. And becomes a refrigerant liquid. Condenser 2
The refrigerant liquid in 6 is decompressed by the decompressor 29 via the intermediate pipe 28, and then flows into the evaporator 31 via the intermediate pipe 30.

On the other hand, the adsorbent 4 in the second adsorption / desorption device 2
Is cooled by the cooling fluid flowing through the heat exchange pipe 6 to generate an adsorption action and adsorb the refrigerant vapor. Then, the pressure inside the second adsorbing / desorbing device 2 is reduced by the adsorption of the refrigerant vapor, so that the refrigerant liquid in the evaporator 31 evaporates, and the evaporation causes the refrigerant liquid itself to be cooled and its temperature to drop.

The evaporator 31 having a low temperature in this way
The refrigerant liquid in the inside is diverted by the circulation pump 39 to the outward pipe 36.
Is supplied to the heat exchanger 38 via the blower fan 4
1 heat-exchanges with the air sent into the vehicle compartment 43 to cool the air, and the evaporator 3 via the return pipe 37.
After being returned to the inside of No. 1 and mixed with the refrigerant liquid flowing in from the condenser 26 side, it is supplied again to the heat exchanger 38 via the return pipe 36, and so on.

Here, from the return pipe 37 to the evaporator 31
The temperature of the refrigerant liquid returned to the inside is raised by cooling the air blown into the vehicle interior 43 by the heat exchanger 38, and the refrigerant liquid stored in the evaporator 31 is evaporated by itself. Since the temperature has dropped, the return pipe 37
The refrigerant liquid returned to the inside of No. 1 is cooled by exchanging heat with the refrigerant liquid inside the evaporator 31 by mixing with the low temperature refrigerant liquid inside the evaporator 31. The liquid is again supplied to the heat exchanger 38 via the outward pipe 36, where the air sent to the vehicle interior is cooled again. Then, the refrigerant vapor in the evaporator 31 flows into the second adsorption / desorption device 2 through the intermediate pipe 32, the three-way switching valve 33, and the return pipe 34 in this order, and is adsorbed by the adsorbent 4.

By the cooling operation as described above, the first suction /
When the desorber 1 completes the desorption operation and the second suction / desorption device 2 finishes the adsorption operation, this state is detected by the detection means (not shown) and the three-way switching valves 8, 12, 17, 2 are detected.
0, 25, 33 are switched as shown by the broken line in FIG. As a result, the second suction / desorption device 2 becomes the desorption side,
The first adsorption / desorption device 1 is switched to the adsorption side.

In this state, the refrigerant vapor desorbed from the adsorbent 4 of the second adsorption / desorption device 2 flows into the condenser 26 through the outflow pipe 24, the three-way switching valve 25 and the intermediate pipe 27 in this order, It condenses into a liquid refrigerant. The refrigerant liquid flows into the evaporator 31 via the pressure reducer 29, is mixed (heat exchanged) with the refrigerant liquid returning from the heat exchanger 38 to the evaporator 31 via the return pipe 36, and evaporates. , The refrigerant vapor is
It flows into the first adsorption / desorption device 1 through the intermediate pipe 32, the three-way switching valve 33, and the return pipe 34 in this order, and is adsorbed by the adsorbent 3. Then, when the second suction / desorption device 2 completes the desorption operation and the first suction / desorption device 1 finishes the adsorption operation, this state is detected by the detection means (not shown), and the three-way switching valves 8 and 12 are detected. , 17, 20, 25, 33 are switched as shown by the solid line in FIG.
By repeating the operation of alternately setting the second adsorption / desorption devices 1 and 2 to the desorption side and the adsorption side, the adsorbents 3 and 4 alternately desorb and adsorb the refrigerant, and the heat exchanger 38
The interior of the vehicle compartment 43 is cooled via the.

As described above, according to this embodiment, the heat exchanger 38 for exchanging heat with the air sent into the vehicle compartment 43 is provided, and the evaporator 31 exchanges heat with the heat exchanger 38. Therefore, there is no restriction on the installation position of the evaporator 31, and the evaporator 31 may be installed at any position in the engine room 42 instead of in the dashboard 45. Therefore, even if there is a restriction that the arrangement position of the condenser 26 is limited to the front part of the engine room 42, the first and second adsorbing / desorbing devices 1 and 2 and the evaporator 31 are connected to the condenser 26. By arranging them close to each other, it is necessary to form a pipe having a large diameter in order for the refrigerant vapor to flow, namely,
Outflow pipes 23 and 24, which connect the second adsorbing / desorbing devices 1 and 2 to the condenser 26 and the evaporator 31, an intermediate pipe 27,
The length 32 and the return pipes 34, 35 can be shortened.

By disposing the evaporator 31 close to the condenser 26, even if the distance between the evaporator 31 and the heat exchanger 38 becomes long, the evaporator 31 and the heat exchanger 38 are separated from each other. Since the refrigerant liquid flows through the forward path pipe 36 and the return path pipe 37 which are connected to each other, both the pipes 46 and 37 are connected.
It is not necessary to configure the pipe with a large diameter pipe, and the pipe can be configured with a small diameter pipe.

From the above, by providing the heat exchanger 38, the first and second adsorption / desorption devices 1 and 2 and the condenser 26 are provided.
And the evaporator 31 can be arranged close to each other, and even if the heat exchanger 38 is provided, the pipes through which the refrigerant vapor flows are connected to the first and second adsorption / desorption devices 1 and 2 and the condenser 26. Can be stopped in the pipelines (pipes 23, 24, 27) connecting them and the pipelines (pipes 32, 34, 35) connecting the evaporator 31 and the first and second adsorbing / desorbing devices 1, 2. In this way, it is possible to shorten the length of the pipeline that needs to be configured with those large-diameter pipes, reduce the piping space, and reduce the pressure loss of the refrigerant vapor. The effect can be obtained.

Further, since the refrigerant liquid stored in the evaporator 31 is used as a heat exchange medium which circulates between the heat exchanger 38 and the heat exchanger 38, the refrigerant liquid whose temperature has risen in the heat exchanger 31 is its own. Since the refrigerant liquid in the evaporator 31 is heat-exchanged by mixing with the refrigerant liquid in the evaporator 31 which has a low temperature due to evaporation, the heat exchange between the evaporator 31 and the heat exchanger 38 is performed. Higher efficiency.

That is, as shown in FIG.
A heat exchanger HE is provided inside, and the heat exchanger HE and the heat exchanger 38 are connected by a forward path side pipe 36 and a return path side pipe 37, and a heat exchange medium between the heat exchanger HE and the heat exchanger 38. For example, it is conceivable to circulate water, but this makes it possible to achieve 100% heat exchange efficiency when heat is exchanged between the heat exchange medium flowing in the heat exchanger HE and the refrigerant liquid in the evaporator 31. Since it is not desired, the heat exchange efficiency decreases.
However, in this embodiment, since the refrigerant liquid in the evaporator 31 is used as the heat exchange medium flowing in the heat exchanger 38, the refrigerant liquid returned from the heat exchanger 38 into the evaporator 31 is the evaporator 31.
Heat will be exchanged by mixing with the refrigerant liquid in the
% Heat exchange efficiency can be obtained.

FIG. 3 shows another embodiment of the present invention.
The difference from the first embodiment is that in addition to the evaporator 31, the condenser 2
6 is also configured to exchange heat with the outside air via the heat exchanger 46. That is, the condenser 26 is formed in a container shape, and one end side of a forward path side pipe 47 and a return path side pipe 48 that form a circulation path are connected to the bottom side and the upper side thereof, and the forward path side pipe 47 and The other end of the return pipe 48 is connected to the inlet 46a and the outlet 46b of the heat exchanger 46. Then, a circulation pump 49 is provided in the middle of the outward pipe 47, and when the circulation pump 49 is activated, the refrigerant liquid in the condenser 26 is discharged between the condenser 26 and the heat exchanger 46. It circulates in.

In this structure, a certain amount of refrigerant liquid is stored in the condenser 26 when the operation is stopped. When the cooling operation is started in this state, the circulation pump 49 supplies the refrigerant liquid in the condenser 26 to the heat exchanger 46 through the outward pipe 47, and here the external air blown by the blower fan 40. It is cooled by exchanging heat with. The cooled refrigerant liquid is returned to the condenser 26 via the return pipe 48,
Here, the refrigerant liquid mixed with the refrigerant liquid stored in the condenser 26 is cooled. Then, the refrigerant liquid in the condenser 26 cools and condenses the refrigerant vapor sent from the first adsorption / desorption device 1 or the second adsorption / desorption device 2.

According to the present embodiment thus constructed, the condenser 26 exchanges heat with the air outside the vehicle via the heat exchanger 46, so that there is no restriction on the installation position of the condenser 26.
Moreover, since the refrigerant liquid flows through the outward-path side pipe 47 and the return-path side pipe 48 that connect the condenser 26 and the heat exchanger 46, both pipes 47, 48 can be configured with small diameter pipes. Therefore, there is no restriction on the positions of the first and second adsorbing / desorbing devices 1 and 2, the condenser 26, and the evaporator 31, and they should be placed close to each other in the empty space in the engine room. Can be placed. As a result, the heat exchanger 46 located in the front of the engine compartment 42 for the condenser 26 to exchange heat with the outside air.
The large-diameter pipe does not become long in the engine room 42 even when the pipe is separated from.

The present invention is not limited to the embodiments described above and shown in the drawings, and the following expansions and modifications are possible. The evaporator 31 may be arranged in the dashboard 45 to directly exchange heat with the air sent into the vehicle compartment 43, and only the condenser 26 may exchange heat with the air outside the vehicle via the heat exchanger 46. In this case, the first and second suction / desorption devices 1 and 2 and the condenser 26 are installed in the engine room 4
The pipes 23, 24, 27, 32, 34, and 35 through which the refrigerant vapor passes can be shortened by disposing the pipes at the rear part of the second pipe.

Metal wool, foam metal, etc. are accommodated in the evaporator 31 in a state where the lower part is immersed in the refrigerant liquid, and the refrigerant liquid is sucked up by the metal wool, foam metal, etc. to promote evaporation. Is also good.
