Abstract (en)

A control device (20) is provided with a temperature acquisition unit (21) which acquires, in a refrigerant circuit which is provided with a heat exchanger (2, 4) and a compressor (1) connected to the heat exchanger (2, 4), a temperature of the compressor (1), a temperature of the heat exchanger (2, 4), and an outside air temperature, and an electrification control unit (22) which performs turn-on control or turn-off control of a crankcase heater (9) which heats the compressor (1) based on the temperature difference between the temperature of the compressor (1) and the temperature of the heat exchanger (2, 4) when the outside air temperature acquired by the temperature acquisition unit (21) is a temperature included in one range of a plurality of pre-decided temperature zones while the compressor (1) is stopped.
