Abstract

The invention relates to the technical field of air conditioning, in particular to an air conditioner heat storage control method. The problems that according to an existing preheating scheme, the service life of a compressor is short, and fluctuation of the temperature of a coil pipe is large are solved. In order to achieve the purpose, the air conditioner comprises a compressor, a throttling element, an outdoor heat exchanger, an outdoor draught fan, an indoor heat exchanger and an indoor draught fan, and the outdoor draught fan is an alternating-current draught fan; and the heat storage control method comprises the steps that the compressor is controlled to operate at a first heat storage frequency; when, before or after the compressor starts to operate, the outdoor draught fan is controlled to operate; in the process that the compressor operates at the first heat storage frequency, the coil pipe temperature of the indoor heat exchanger is detected; the coil pipe temperature and a first preset temperature are judged; and based on the judgment result, the opening and closing of the outdoor draught fan and / or the operation frequency of the compressor are / is selectively adjusted. According to the heat storage control method, the service life of the compressor can be prolonged, fluctuation of the temperature of the coil pipe in the air conditioner heat storage process is reduced, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning heat storage control method. Background technique [0002] When the air conditioner is turned on in cold winter, due to the low indoor and outdoor temperature, the wind blown after the air conditioner is turned on at this time 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 ...
