<P>PROBLEM TO BE SOLVED: To improve the reliability of a compressor by preventing a temperature rise of the compressor caused by overshoot of a discharge temperature. <P>SOLUTION: In this heat pump device comprising a refrigerant circuit and a discharge temperature sensor 15 for detecting a discharged-refrigerant temperature of the compressor 11, a discharge temperature control means 23 is mounted for stabilizing the discharge temperature in starting the operation of the compressor 11 on the basis of a target discharge temperature, after the discharge temperature is almost stabilized on the basis of the initial discharge temperature slightly lower than the target discharge temperature. Thereby the overshoot of the discharge temperature of the compressor 11 in starting the operation can be prevented, and the reliability of the compressor 11 can be improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
