Patent ID: 11472266

Abstract:
A transport refrigeration system (200) including: a refrigeration unit (22) having a refrigerant heat rejection heat exchanger (34) and a fan (40) configured to blow air across the refrigerant heat rejection heat exchanger; a first engine (26) configured to power the refrigeration unit (22), the first engine (26) having an engine coolant circuit (80) and an exhaust outlet (27); a heat exchanger (70) having: a first fluid passage (72) fluidly connected to the exhaust outlet (27); and a second fluid passage (74) fluidly connected to the engine coolant circuit (80); and a third fluid passage (76) fluidly connected to and configured to receive air blown across the refrigerant heat rejection heat exchanger (34). The second fluid passage (74) is thermally connected to the first fluid passage (72) and the third fluid passage (76) is thermally connected to the first fluid passage (72).
