Thermal energy recovery device and thermal energy recovery method

摘要

A thermal energy recovery system (10) comprises: a heating medium circuit (12) adapted to be connected to a heat source heat exchanger 1; a first binary generator (14) including a first heater (14b); a second binary generator (16) including a second heater (16b) for heating a second working medium by the heating medium in a lower temperature range than in the first heater (14b); and a regenerative heat exchanger (18) for heating the heating medium flowing from the second heater (16b) toward the heat source heat exchanger (1) by the heating medium flowing from the first heater (14b) toward the second heater (16b).
