Rankine Cycle

---

Abstract

---

The Rankine cycle (31) includes a refrigerant pump (32), a heat exchanger (36), an expander (37), and a condenser (38). The Rankine cycle (31) shares the condenser (38) and refrigerant with a refrigerant cycle of an air-conditioner. A refrigerant passage connecting to an outlet of the condenser (38) branches at a refrigeration cycle branch point (45) to connect to the refrigerant pump (32) and an evaporator (55). In the case of operating the Rankine cycle, without a request to operate the air-conditioner, the compressor (52) in the refrigeration cycle is driven.
