When the refrigerant gas compressed by the compressor is circulated in the first heat exchanger of the first heat exchanger and the second heat exchanger,
In the heat exchanger of the first heat exchanger, the refrigerant liquid produced by liquefying the refrigerant gas is expanded by a valve, decompressed, cooled, and then circulated to serve as a cooling medium. The mixed liquid of the absorbing liquid and the refrigerant is heated in the first room including the exchanger to generate the refrigerant vapor. Due to the generation of the refrigerant vapor, the mixed liquid is concentrated and the concentration of the absorbing liquid is increased to further enhance the absorbing ability of the absorbing liquid. Further, the refrigerant vapor generated in the first chamber enters the second chamber having the second heat exchanger through the vapor passage, and the invading refrigerant vapor circulates in the second heat exchanger. It is cooled and liquefied by the cooling medium, and the liquefied refrigerant dilutes the refrigerant concentration in the second chamber to further enhance the evaporation ability. In this way thermal energy is stored. When the cold storage heat is to be taken out, the concentrated absorbing liquid is sprayed to the first heat exchange coil by the first spraying device to take out hot water for heating from the first heat exchange coil, and the thinned refrigerant to the second heat exchange coil. The cold water for cooling is taken out from the second heat exchange coil by spraying the liquid with the second spray device.

Due to the compression by the compressor 1, the refrigerant gas (generally CFC type) becomes high temperature and high pressure, and the pipe 8, the four-way switching valve 3, the pipe 9, the valve 17
To the first heat exchanger 4, and the mixed liquid is heated while flowing through the first heat exchanger 4 to evaporate the refrigerant from the mixed liquid and increase the absorption liquid concentration of the mixed liquid. As a result of heating the mixed liquid, the first heat exchanger 4
Liquefied the refrigerant, piping 10, valve 18, air-cooled heat exchanger 6, piping 11,
The pressure is reduced by the valve 18 or the valve 19 through the pipe 12 and the valve 19 and then flows into the second heat exchanger 5. This refrigerant liquid takes the latent heat of vaporization from the surroundings (second chamber 23B) in the second heat exchanger 5 to evaporate, evaporates in the first chamber 23A and flows in through the opening 25 into the second chamber. Room 23B by liquefying the refrigerant vapor in 23B
Collects at the bottom of the. The refrigerant gas evaporated in the second heat exchanger 5 returns to the compressor 1 via the pipe 13, the valve 20, the pipe 14, the four-way switching valve 3 and the pipe 7, and is compressed again in the compressor 1. While continuing the above operation, the mixed liquid in the first chamber 23A is concentrated and the concentration of the absorbing liquid becomes higher, and in the second chamber 23B, the refrigerant vapor evaporated in the first chamber 23A. The refrigerant liquid that has condensed is accumulated. As a result, the mixed liquid in the first chamber 23A is concentrated and has a large absorption capacity, and if it absorbs the refrigerant vapor, it generates absorption heat, in other words, it stores heat. . Also, the second room 23B
Since the refrigerant liquid is in a liquid state, it has the ability to evaporate, and therefore, it stores cold power corresponding to the latent heat of evaporation at the time of evaporation and stores cold.

In the course of this cold storage heat operation, since the first chamber 4 and the second chamber 5 are in a thermal equilibrium state, the power generated in the compressor 1 is externally cooled by an amount corresponding to the amount of heat converted. There is a need. This is cooled by the air-cooling heat exchanger 6. At this time, when the outside air temperature is sufficiently low, it is advantageous in cycle efficiency to add the cooling by the air-cooling heat exchanger 6 in addition to the cooling power generated in the second heat exchanger 5, and the outside air temperature is high. At this time, the cooling power of the air-cooled heat exchanger 6 must act as a condenser of the compressor refrigeration cycle in addition to the first heat exchanger 4. In order to switch between the two, when the outside air temperature is sufficiently low and the refrigerant can be cooled to the operating level of the second heat exchanger 5, the valve 18 is set to a small opening degree to operate as an expansion valve, and the valve 19 is completely opened. Try to open it. When the outside air temperature is high, the valve 18 is completely opened so that the air-cooling heat exchanger 6 together with the first heat exchanger 4 operates as a condenser, and the valve 19 has a small opening and operates as an expansion valve.

The refrigerant liquid in the second chamber 23B is sprayed by the pump 29 from the spray header 31 to the second heat exchange coil 27 and evaporated. When the refrigerant evaporates, the latent heat of vaporization is taken from the heat medium flowing in the heat exchange coil 27 to cool the heat medium. Thereby, the cold power is taken out. The refrigerant vapor evaporated in the second chamber 23B flows into the first chamber 23A through the opening 25.

Further, in order to use the stored concentration energy more effectively, it is possible to operate by the following configuration in addition to the above method. In the above method, the energy stored by the concentration is absorbed by the absorption liquid of the refrigerant vapor, and the energy is taken out in a form in which the concentration decreases, but when the absorption liquid concentration of the mixed liquid falls below a predetermined value, the first Therefore, it becomes impossible to generate a required temperature difference between the second heat exchange coils 26 and 27. At this time, in the process that requires cooling power, the valves 17 and 21 are opened, the four-way switching valve 3 is set to the arrow B, the valve 18 is set to a small open, and the other valves are set.
Close 19,20,22. Then, the refrigerant that has cooled the first heat exchanger 4 and evaporated is sucked into the compressor 1, and after being compressed, it passes through the four-way switching valve 3 and the pipes 14, 15 and 11 and the air-cooled heat exchanger 6
Therefore, it is cooled by the outside air and condensed. The valve 18 is slightly opened to the extent that it becomes an expansion valve. Since the mixed liquid is sprayed in the first room 23A, the refrigerant vapor evaporated in the second room 23B is absorbed while the mixed liquid is being cooled.
これにより、第2の部屋23Bでは継続して冷媒蒸気が発
生し、冷却能力を出し続けることができる。
As a result, the refrigerant vapor is continuously generated in the second room 23B, and the cooling capacity can be continuously produced.
