<P>PROBLEM TO BE SOLVED: To provide a heat pump including an exhaust-heat heat exchanger between a compressor and a condenser, capable of accurately and appropriately controlling its operating condition although operation control of the heat pump is simple and easy. <P>SOLUTION: This heat pump employs a structure where an exhaust-heat heat exchanger 5 for providing exhaust heat to a refrigerant is arranged between a compressor 2 and a condenser 11, and the refrigerant circulates through the compressor 2, the exhaust-heat heat exchanger 5, the condenser 11, an expansion valve 3 and an evaporator 4 in this order and returns to the compressor 2. The heat pump includes an operation control means 74 to bring the state of the refrigerant at an entrance 2in of the compressor into a gas-liquid mixture state having a level of dryness of <1, and bring the state of the refrigerant at the output 2out of the compressor into a superheated state, wherein the refrigerant in the superheated state is entered in the exhaust-heat heat exchanger 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
