HEAT PUMP DEVICE, AIR CONDITIONER, AND COOLING MACHINE

摘要

A heat pump device includes a compressor 1 including a compression mechanism 7 that compresses a refrigerant and a motor 8 that drives the compression mechanism 1, an inverter 9 that applies a voltage for driving the motor 8, a converter 10 that applies a voltage to the inverter 9, an inverter control unit 12 that generates a driving signal for driving the inverter 9, and a converter control unit 17 that generates a driving signal for driving the converter 10, wherein the inverter control unit 12 includes a heating operation mode in which a heating operation of the compressor 1 is performed and a normal operation mode in which a refrigerant is compressed by performing a normal operation of the compressor 1 and the converter control unit 17 sets, in the heating operation mode of the inverter control unit 12, a voltage applied to the inverter 9 on the basis of a voltage command value for the motor 8.
