WASTE HEAT REGENERATION SYSTEM

摘要

A waste heat regeneration system includes a pump, a coolant boiler, an exhaust gas boiler, an expander, a condenser, a gas-liquid separator and a supercooler. A flow control valve maintains a temperature difference (T1 - T2) at a predetermined value or less by adjusting the amount of an operating fluid which flows in a bypass flow path through the control of an opening degree based on a pressure difference (P1 - P2) corresponding to the temperature difference (T1 - T2) between the temperature (T1) of the operating fluid on the upstream side of the supercooler and the temperature (T2) of the operating fluid on the downstream side thereof. Accordingly, the degree of supercooling is prevented from becoming excessive and the waste heat regeneration efficiency of a Rankine cycle device can be maintained.
