Abstract

An engine-driven refrigeration unit includes a first heat exchanger functioning alternatively as a refrigerant condenser or as a refrigerant evaporator. When the heat exchanger is functioning as a refrigerant evaporator the heat transfer medium furnished thereto for providing a source of heat to vaporize the refrigerant is preheated by absorbing heat from a relatively warm fluid employed as the cooling medium for the engine driving the refrigeration unit.
