For example, for the cooling mode, the compressor is controlled to perform a down-conversion operation as the current target reference temperature is 24 ℃ when the difference between the indoor temperature value and the target reference temperature is smaller, if the indoor temperature is reduced from 30 ℃ to 25 ℃, if a further reduction of the indoor temperature value is detected, the compressor is controlled to perform the down-conversion operation when the difference between the indoor temperature value and the target reference temperature is smaller, and finally, when the indoor temperature reaches 24 ℃, the compressor is controlled to perform the down-conversion operation at a preset low frequency, so that the indoor temperature value is finally and smoothly maintained near the target reference temperature value (for example, the difference between the indoor temperature and the target reference temperature is 0.1 degree or 0.2 degree, and the like), and the fluctuation of the indoor temperature at the target reference temperature is not too large, so as to improve.
