る。 That is, the concentrated solution that enters the heat collection unit 2 from the concentrated solution inlet 7 receives heat from the sun 1 in the generator 5, generates refrigerant vapor, rises to the separator 6, and generates refrigerant (e.g., fluorocarbon) vapor. and a dilute solution (mostly absorbent (for example, NN-dimethylformamide) and the remainder refrigerant). This refrigerant vapor enters the condenser 9 of the outdoor unit 3, where it is cooled by a cooling device including an air blower 12, condenses and becomes a liquid refrigerant, and flows to the indoor unit 4.
一方、前記希溶液は、発生器５内で、前記濃溶

It is further cooled by heat exchange with the concentrated solution pumped to the generator 5. and,
The dilute solution exits from the solution heat exchanger dilute solution outlet 13a, is depressurized by the pressure reducer 15, and is transferred to the evaporator 20 in the indoor unit 4.
The refrigerant vapor enters the absorber 11 after being mixed with the refrigerant vapor returning from the refrigerant vapor.
In the absorber 11 , the refrigerant vapor is cooled by cooling air from the blower 12 , and the refrigerant vapor is absorbed by the dilute solution to become a concentrated solution, which exits the absorber 11 and is sent to the solution heat exchanger 13 by the solution pump 14 .

生じた冷媒蒸気は、前述のように、減圧器１５で
減圧された希溶液と混合して吸収器１１に入る。 The liquid refrigerant flowing from the condenser 9 to the indoor unit 4 is depressurized and expanded in the decompressor 21, and is expanded into the evaporator 2.
0, where it evaporates into low-pressure refrigerant vapor. The latent heat of vaporization at this time cools the air flowing through the blower 22, thereby cooling the room. The refrigerant vapor generated here mixes with the dilute solution whose pressure has been reduced by the pressure reducer 15 and enters the absorber 11, as described above.
次に、日射が少なくなつた場合を説明する。こ

で、圧縮器１０は高い吸入圧力で運転され、エネ
ルギ効率はよい。したがつて圧縮機１０の消費電
力は少なくてすむ。 If there is less solar radiation, the amount of refrigerant generated by the generator 5 will be smaller. Therefore, when the compressor 10 is operated, the inside of the generator 5 becomes the suction side of the compressor 10 and generates refrigerant at a pressure corresponding to its temperature. The high-pressure refrigerant compressed by the compressor 10 enters the condenser 9 and is liquefied, forming the same cycle as in the case where there is sufficient solar radiation as described above. In this case, generator 5
has the role of a booster for the compressor 10, so the compressor 10 is operated at high suction pressure and has good energy efficiency. Therefore, the power consumption of the compressor 10 can be reduced.

At this time, the valve 18 is opened, the valves 16, 17, and 19 are closed, and the compressor 10 is operated to operate in a compression type refrigeration cycle. That is, compressor 10, condenser 9, pressure reducer 2
