Patent ·
OSTI ID:6403132
An open Rankine cycle heat pump that utilizes a multistage compressor having interstage desuperheating wherein process fluid in the form of water drawn from a waste heat producing process is used as the working fluid in the heat pump thereby eliminating the need for heat exchangers at the conventional evaporator and condensor locations. Heated return water drawn from the process is flashed to a vapor and the vapors passed through the compressor to provide thermal energy that is used in compatible process related equipment.
