Abstract (en)
[origin: EP3546846A1] A controller includes an operation control unit that controls operations of a compressor, an expansion device, and a feeding device. When the operation control unit starts heating operation for storing heated water in a tank, the operation control unit starts operating both the compressor and the feeding device together. The operation control unit operates the compressor at a first compressor rotation speed until a preset first time period elapses from when the heating operation is started. After a lapse of the first time period, the operation control unit operates the compressor at a second compressor rotation speed higher than the first compressor rotation speed.
