Abstract

The invention relates to the technical field of air conditioning, in particular to a heat storage mode control method for an air conditioner. The control method aims to solve the problems of short compressor service life and large coil temperature fluctuation in an existing preheating scheme. The heat storage mode control method comprises the steps that a preset startup moment is corrected based on time correction parameters; a heat storage starting moment of the air conditioner is calculated based on the corrected preset startup moment and preset heat storage time; when the heat storage starting moment is reached, a compressor is controlled to operate at heat storage frequency, and an outdoor fan is controlled to operate; first coil temperature of an indoor heat exchanger is detected; when the first coil temperature is higher than first preset coil temperature, second coil temperature of the indoor heat exchanger is detected at the interval of set time and compared with the first preset coil temperature; and based on the judgment result, the operating frequency of the compressor and the opening and closing of the outdoor fan are adjusted. According to the heat storage mode controlmethod, the service life of the compressor can be prolonged, and the fluctuation of the coil temperature in the heat storage process can be reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat storage mode control method of an air conditioner. Background technique [0002] When the air conditioner is turned on in cold winter, due to the low indoor and outdoor temperatures, the air blown out after starting the air conditioner is cold wind, which seriously affects the user experience. For this reason, the existing air conditioners are equipped with an anti-cold wind mode. When the anti-cold wind mode is activated, the compressor and the outdoor fan are controlled to store heat, and then the indoor fan is controlled to run after the temperature rises, which avoids the situation of blowing out cold wind when the machine is turned on. However, in practical applications, the air conditioner waits for a long time due to running the anti-cold wind mode within a few minutes after starting up, which will give the user the feeling that the air conditioner has a pr...
