DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adsorptive refrigerator that utilizes the adsorption and desorption of refrigerant vapor by an adsorbent.

[0002]

2. Description of the Related Art FIGS. 19 and 20 show a conventional general adsorption refrigerator. This adsorption refrigerator has a first adsorption module 5 as an adsorption module having an adsorbent.
The first and second adsorption modules 52 are provided, and a condenser 53, an evaporator 54, and an expansion valve 55 are connected to the pair of first adsorption modules 51, 52 by a refrigerant circulation path 60.

[0003] This adsorption type refrigerator is of a so-called batch type, and continuous operation is possible by switching the control valves 56 to 59 provided in the refrigerant circuit 60.
That is, as shown in FIG. 19, the control valves 56 and 59 are opened, and the control valves 57 and 58 are closed. In this state, the first adsorption module 51 is heated, and the second adsorption module 5 is heated.
When the second cooling module 2 is cooled, the refrigerant (for example, water) adsorbed by the adsorbent in the first adsorption module 51 evaporates and the adsorbent 21 is regenerated, while the second adsorption module 52 evaporates. The refrigerant vapor (water vapor) generated in the device 54 is adsorbed on the adsorbent. And
The refrigerant vapor generated in the first adsorption module 51 is sequentially condensed in the condenser 53 to become a liquid refrigerant, and the liquid refrigerant is decompressed in the expansion valve 55 and then evaporated in the evaporator 54. It becomes refrigerant vapor and is sequentially adsorbed on the second adsorption module 52 side. At this time, the condensation heat (warm heat) generated in the condenser 53 or the evaporation heat (cold heat) generated in the evaporator 54 is used as a heat source for heating or cooling.

[0004] With the continuation of the above operation, the first adsorbing module 51 is regenerated by evaporation of the retained refrigerant, while the second adsorbing module 52 is in a saturated state, and the capacity of the adsorption refrigerator becomes extremely high. It is going down.
Therefore, in this case, each of the control valves 56 to 59 is switched to the state shown in FIG. 20, and the first adsorption module 51 cools it, and the second adsorption module 52 heats it. In the first adsorption module 51, refrigerant vapor is adsorbed.
The adsorption module 52 regenerates the refrigerant by desorption of the refrigerant.

As described above, the control valves 56 to 59 are switched at predetermined intervals to cause the first adsorption modules 51 and 52 to alternately perform the adsorption operation and the desorption operation, thereby enabling continuous operation of the adsorption refrigerator. It is what becomes.

[0006]

When the refrigerant adsorbs the refrigerant vapor, heat of adsorption is generated in the adsorbent 21 along with the adsorption of the refrigerant vapor. Therefore, it is considered that the heat of adsorption is recovered to improve the thermal efficiency of the entire adsorption refrigerator.

However, in a conventional general adsorption refrigerator, as described above, a pair of adsorption modules 51 and 52 are used.
Is a batch method in which an adsorption action and a desorption action are alternatively performed, and no means is provided for recovering the heat of adsorption generated in the adsorbent. Therefore, there is a limit to the improvement of the coefficient of performance (hereinafter, abbreviated as “COP”) of the entire adsorptive refrigerator.

Accordingly, the present invention provides an adsorption type refrigerator capable of realizing a high COP by utilizing the heat of adsorption generated by the adsorption of refrigerant vapor in the adsorbent as one of the heat sources for regeneration of the adsorbent. It is done for the purpose of.
