A method of controlling an air conditioner includes a step of controlling an opening degree of the expansion valve and/or the number of rotations of an outdoor fan of the outdoor heat exchanger such that the difference Tx (= Te - Ti) between the temperature Te of the outdoor heat exchanger and the temperature Ti of the indoor heat exchanger is within a predetermined range, in a cooling mode in a low outside air temperature environment. Specifically, the opening degree of the expansion valve is adjusted, with the number of rotations of the outdoor fan being reduced to be smaller than that in a normal cooling mode, and then, the number of rotations of the outdoor fan is adjusted with the opening degree of the expansion valve being fixed, thereby controlling the difference Tx to be substantially constant. |
