RANKINE CYCLE DEVICE

摘要

Disclosed is a Rankine cycle device including a waste heat source, an operating fluid circuit, and a limiting unit. The operating fluid circuit is configured by sequentially connecting a pump, a heat exchanger, an expander, and a condenser. The pump delivers under pressure the operating fluid. The heat exchanger subjects the operating fluid, which is delivered from the pump under pressure, to heat exchange with waste heat from the waste heat source. The expander outputs mechanical energy by expanding the operating fluid having been subjected to the heat exchange at the heat exchanger. The condenser condenses the operating fluid expanded by the expander. The limiting unit limits the amount of heat which, on the basis of temperature information detected at the inlet of the pump or the inlet of the expander, the operating fluid receives in the portion of the operating fluid circuit which extends from the outlet of the pump to the inlet of the expander.
