[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adsorption type refrigeration system equipped with an adsorption / desorption device in which an adsorbent for adsorbing and desorbing a refrigerant is circulated.

[0002]

2. Description of the Related Art As a refrigerating device used in, for example, a refrigerator, a household air conditioner, a car air conditioner, an adsorption type refrigerating device using water as a refrigerant is known. This is because an adsorbent such as silica gel or zeolite adsorbs a gaseous refrigerant in a cooled state and desorbs the adsorbed refrigerant in a heated state. In such an adsorption type refrigerating apparatus, in recent years, for example, Japanese Patent Laid-Open No. 3-199 has been used.
As shown in Japanese Patent Publication No. 864, a method of circulating an adsorbent in an adsorption / desorption device has been considered.

In this device, a vertically extending cylinder is arranged in the center of a container filled with the adsorbent, and a screw conveyor is provided in the cylinder to raise the adsorbent in the cylinder. At the outer side of the cylinder (between the inner wall of the container), the circulation for lowering the adsorbent is performed. Then, outside the container, a heat exchanger for heating is provided on the upper side, and a heat exchanger for cooling is provided on the lower side. Further, the upper side of the container is connected to the condenser (condenser), the lower side is connected to the evaporator (evaporator), and further, the condenser and the evaporator are connected by piping.

In this way, the gas refrigerant adsorbed by the adsorbent is desorbed in the upper part of the container and supplied to the condenser, becomes liquid refrigerant (water) in the condenser, and is supplied to the evaporator through the pipe. The refrigerant vaporized in the evaporator is adsorbed by the adsorbent in the lower part of the container. And the adsorbent that adsorbed the refrigerant is the container (cylindrical)
The advancing agent that has risen inward toward the upper part and descends the refrigerant in the upper part is descended, and the continuous cooling operation is possible.

[0005]

However, in the above-mentioned conventional one, since the circulation mode of the adsorbent is such that the inner peripheral side (in the cylinder) of the container is raised and the outer peripheral side is lowered, the above-mentioned heating, Since the heat exchanger for cooling is arranged on the outer peripheral wall of the container, there is a drawback that the heat exchange efficiency is poor. In this case, if the fins of the heat exchanger are made to project into the container, the heat exchange efficiency will be improved, but this will complicate the configuration.

Therefore, the inventors of the present invention considered the structure of the adsorption / desorption device 1 as shown in FIG. In this, the container 2 filled with the adsorbent S is configured in a substantially rectangular ring shape, and a screw conveyor 3 for raising the adsorbent S and circulating it in the direction of arrow A is provided on the left side in the figure, On the right side, a heat exchanger 4 for heating and a heat exchanger 5 for cooling are vertically provided. Then, the desorbed refrigerant is supplied to the condenser 7 from the discharge passage 6 connected to the upper portion of the heat exchanger 4, and is passed from the evaporator 9 through the suction passage 8 connected to the upper portion of the heat exchanger 5. The gas refrigerant is adsorbed.

In this case, the heat exchangers 4 and 5 are constructed by adding fins or the like to pipes through which the heat exchange fluid flows,
Heat is exchanged when the adsorbent S passes between the pipe and the fin. According to this, the heat exchangers 4, 5
Can be disposed inside so as to be embedded in the adsorbent S, and the heat exchange efficiency with respect to the adsorbent S can be improved.

However, in the configuration of FIG. 8 as described above, the refrigerant is discharged from the discharge passage 6 through a portion where the adsorbent S is substantially densely packed, or the adsorbent S is substantially densely filled from the suction passage 8. Since it is adsorbed by the adsorbent S through the filled portion, the movement of the refrigerant is not so smooth, the amount of movement of the refrigerant per unit time is small, and the efficiency is poor. It is predicted that a problem that cannot be obtained will occur.

The present invention has been made in view of the above circumstances. An object of the present invention is to provide an adsorbent circulation type adsorption / desorption device, which can smoothly move a refrigerant relating to adsorption and desorption. It is an object of the present invention to provide an adsorption type refrigerating apparatus which can improve the cooling performance.

In the adsorption refrigeration apparatus of the first aspect, the refrigerant liquefied by the condenser is supplied to the evaporator, and is vaporized by heat exchange with the outside in the evaporator, and the outside air is removed. Cooling. Then, the gas refrigerant that has contributed to the cooling of the outside air is sucked into the refrigerant adsorbing portion of the adsorption / desorption device through the suction passage,
It is adsorbed by the adsorbent that has been cooled by the cooling heat exchanger. On the other hand, in the refrigerant desorption part of the adsorption / desorption device, the refrigerant is desorbed from the adsorbent heated by the heating heat exchanger and supplied to the condenser through the discharge passage.

Here, the adsorbent has a reduced adsorbing ability when adsorbing a predetermined refrigerant, and the adsorbing ability is regenerated by desorbing the refrigerant. In the adsorbent / desorber, the adsorbent is circulated. Since the adsorbent is circulated in the adsorbent circulation path by the means, the adsorbent that has adsorbed the refrigerant in the refrigerant adsorbing portion reaches the refrigerant desorbing portion by circulation, desorbs the refrigerant, and then reaches the refrigerant adsorbing portion again. Is repeated. As a result, the circulation of the refrigerant between the condenser, the evaporator, and the adsorption / desorption device is continuously performed, so that the continuous cooling operation is performed.

At this time, since the adsorbing space is provided in the refrigerant adsorbing part of the adsorbing / desorbing device, when the adsorbent is densely located between the suction passage and the cooling heat exchanger part.

Since the desorption space is also provided in the refrigerant desorption section of the adsorption / desorption device, the refrigerant can flow smoothly and in large quantities from the heating heat exchange section to the discharge path.

Moreover, the suction passage and the discharge passage are connected to both the upstream side and the downstream side of the cooling heat exchanger and the heating heat exchanger, respectively, and the adsorption space portion and the desorption space portion are respectively cooled. Since it is configured to be formed both upstream and downstream of the heat exchanger and the heating heat exchanger, the refrigerant is sucked from the suction passage through the adsorption space both upstream and downstream of the cooling heat exchanger. will be, the more it is possible to further increasing the suction amount of the refrigerant, upstream of the heating heat exchanger, it will be released to the coolant through the discharge passage from the detachment space portion downstream of both, more The discharge amount of the refrigerant can be increased.

The screw conveyor 22 is driven by 3, and the heating fluid is supplied to the heating heat exchanger 24 and the cooling fluid is supplied to the cooling heat exchanger 25. Then, the liquid refrigerant (water) of the receiver 13 is sent to the evaporator 15 by the pump 14, where the liquid refrigerant is vaporized by heat exchange with the outside air, and the outside air is cooled.

On the other hand, in the adsorption / desorption device 16, the adsorbent S inside circulates in the adsorbent circulation path 21 in the direction of arrow A by driving the screw conveyor 22. Therefore, the refrigerant
The adsorbent S that has adsorbed the refrigerant in the adsorption section 43 passes through the lower communication section 20b and ascends in the ascending section 20c, and further passes through the upper connection section 20d, and the upper portion of the main body section 20a, that is, the refrigerant desorption.

A predetermined space portion (desorption space portion 35 and adsorption space portion 36) is always secured downstream (downward) of the plates 37, 37.

The gaseous refrigerant desorbed by the refrigerant desorption section 44 is supplied to the condenser 12 through the discharge passage 42 . At this time, the refrigerant desorption unit 44 is for heating.

Thus , the refrigerant can smoothly and efficiently flow from the heating heat exchanger 24 portion to the discharge passage 42 . At this time, since there is a possibility that the adsorbent S flows out to the discharge passage 42, the like net for preventing outflow of adsorbent S is installed between the discharge channel 42 and the adsorption-desorption 16 Is preferred. Then, the gas refrigerant is condensed in the condenser 12 to become a liquid refrigerant (water) and sent to the receiver 13. With such circulation of the refrigerant, continuous cooling operation is performed.

FIG . 5 is a reference for comparison with the configuration of FIG.

As described above, according to the present embodiment, in the adsorption / desorption device 16 that has the refrigerant desorption unit 44 and the refrigerant adsorption unit 43 and circulates the adsorbent S, the desorption for facilitating the circulation of the refrigerant is performed. Separation space 35, downstream desorption space 45, and adsorption space 36
Since the adsorbing space 46 is provided on the downstream side , unlike the conventional one in which the adsorbent S is almost densely packed, the refrigerant relating to adsorption and desorption can be smoothly moved. The amount of movement of the refrigerant per unit time can be increased. As a result, the excellent effect that the refrigerant can be efficiently moved and the cooling performance can be improved can be obtained.

In this embodiment, in particular, the desorption space portion 35 and the adsorption space portion 36 are formed by the partition plate 37 having the circular hole 37a for suppressing the passage of the adsorbent, so that the structure is simple. And the space 3 for adsorption and desorption
