CONTROL METHOD AND DEVICE FOR AIR CONDITIONER

WIPO Patent Application WO/2019/042042

A1

A control method and device for an air conditioner, relating to the technical field of air conditioners. The control method comprises: obtaining the indoor temperature of a space where an air conditioner is located; if the temperature difference between the indoor temperature and a target indoor temperature meets a preset shutdown temperature condition, controlling the initial wind speed gear of an inner fan to be decreased to a target wind speed gear corresponding to the shutdown temperature condition; and if the temperature difference within a set duration during which the inner fan runs at the target wind speed gear still meets the shutdown temperature condition, controlling the compressor to be turned off. By means of the temperature difference between an indoor temperature and a target indoor temperature and by decreasing the wind speed gear, changes in the indoor temperature when indoor cooling air supply is reduced can be determined, so that changes in the indoor temperature after the compressor is stopped can be determined analogously. Thus, start, stop, and operation of the compressor can be accurately controlled, thereby avoiding frequent start and stop of the compressor, and improving a user's comfort.
