Abstract
Purpose To provide a refrigeration cycle capacity enhancement apparatus that, in addition to lowering the temperature of coolant going from a condenser 4 to an evaporator 7, raising the temperature of coolant going from the evaporator 7 to a compressor 3, enhancing the performance thereof, and preventing the return of liquid coolant to the compressor 3, can also keep the pressure on the coolant from becoming higher and higher under high loading. Constitution Taking note of the fact that the capacity of a heat exchanger 5 is raised by combining drain water D from an evaporator 7 with the heat exchanger 5, this is a refrigeration cycle capacity enhancement apparatus that comprises a compressor 3 and a condenser 4 installed on the engine compartment 12 side of a vehicle, and an evaporator 7 installed on the vehicle cabin 13 side thereof. The heat exchanger 5 is provided to exchange heat between the coolant going from the condenser 4 toward the evaporator 7 and the coolant going from the evaporator 7 toward the compressor 3, while drain water D is conveyed to the heat exchanger 5 from the evaporator 7.
