Here, in the case that the shell temperature of the compressor is greater than or equal to the first shell temperature threshold value, it is said that the shell temperature of the compressor is higher, and therefore the heat storage device is turned on at this time, and the heat of the compressor is conducted to the water flowing through the heat storage device, so as to achieve the purpose of reducing the temperature of the compressor itself.
