体ポンプ８により、コレクター１に送り込まれる。Next, the operation of the above configuration will be explained. First, during cooling operation, the working fluid sent to the collector 1 by the working fluid pump 8 is heated by solar heat and becomes high-temperature, high-pressure steam. Since 10-a of the cooling/heating switching pulp A is open and 10-b is closed, the working fluid flows into the expander 13, generates power, drives the compressor 13, and operates the well-known cooling cycle 18. , the cooling heat exchanger 7-a of the indoor unit 6 outputs cooling output. Since the cooling/heating switching pulp 11-a is open and the heating/cooling switching pulp 11-b is closed, the working fluid that has exited the expander 13 passes through the heating heat exchanger bypass passage 12 and passes through the heating heat exchanger? -b does not pass. A large amount of the fluid is condensed in the condenser 15 and sent to the collector 1 again by the working fluid pump 8.

為、冷却されることなく、再び作動流体ポンプ８により
コレクター１に送り込まれる。During heating operation, the working fluid sent to the collector 1 by the working fluid pump 8 is heated to a high temperature, and the cooling/heating switching pulp 1
Since 0-a is closed and 10-b is open, it does not flow through the expander 13 but flows through the expander bypass passage 9, and the cooling/heating switching pulp 11-a is closed and 11-b is open, so the indoor unit It flows into heating heat exchanger 7-b of No. 6, where heating output is generated. Thereafter, the working fluid enters the condenser 16, but since the beam tower 16 is not operating during the heating operation, it is sent to the collector 1 again by the working fluid pump 8 without being cooled.

６より快適な暖房出力を得ることができる。Since the working fluid is directly sent to the collector 1 and heated in this way, the heating temperature of the working fluid can be kept high, and during cooling operation, it becomes high-temperature steam and flows into the expander 13, increasing the efficiency of the Rankine engine. do. Further, even during heating operation with little sunlight, the working fluid can be heated to a high temperature, and a more comfortable heating output than the indoor unit 6 can be obtained.
