Abstract
An energy recovery system and method using an organic rankine cycle is provided for recovering waste heat from an internal combustion engine, which effectively controls condenser pressure to prevent unwanted cavitation within the fluid circulation pump. A coolant system may be provided with a bypass conduit around the condenser and a bypass valve selectively and variably controlling the flow of coolant to the condenser and the bypass. A subcooler may be provided integral with the receiver for immersion in the accumulated fluid or downstream of the receiver to effectively subcool the fluid near the inlet to the fluid pump.
