Here, "adjusting the compressor frequency or/and the indoor unit fan rotation speed" includes three cases: the first case, i.e. adjusting the compressor frequency; in the second condition, the rotating speed of the fan of the indoor unit is adjusted; and in the third situation, the frequency of the compressor is regulated, and the rotating speed of the fan of the indoor unit is regulated.
