Abstract

The invention discloses an air conditioner, a control method of the air conditioner and a computer readable storage medium. According to the control method, the running frequency of a compressor is controlled according to the evaporation temperature firstly, a low-pressure switch is ensured to be not switched off, if the low-pressure switch is switched off, the frequency of the compressor is controlled to be reduced continuously until the low-pressure switch is switched on, then the running frequency of the compressor is controlled to rise, and the maximum running frequency for frequency rising of the compressor does not exceed the limiting frequency, so that the low-pressure switch is ensured to be not switched off. Thus, according to the control method, through adjustment of the runningfrequency of the compressor, when the low-pressure switch is switched off, the compressor is controlled to run continuously, however, the running frequency is reduced, after the low-pressure switch isswitched on, frequency rising control is performed, the running frequency of the compressor is adjusted repeatedly to be in a certain appropriate range, continuous running of an air conditioning system is guaranteed, and the cooling or heating effect is provided continuously.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioner, a control method thereof, and a computer-readable storage medium. Background technique [0002] The refrigeration cycle system of the air conditioner is generally equipped with a low pressure switch. When the pressure at the low pressure switch is lower than the action value of the low pressure switch, the low pressure switch will be disconnected, and the air conditioner will stop running. When the pressure is higher than the action value of the low-pressure pressure switch, the air conditioner restarts to run. Therefore, when the air conditioner is out of operation, cooling or heat cannot be provided to the room, and the user's demand for air conditioning cannot be met. [0003] The above information disclosed in this background technology is only for enhancement of understanding of the background technology of this application, and ther...
