Abstract

The invention relates to the technical field of air conditioning, in particular to an air conditioner heat storage control method and aims at solving the problems that according to an existing preheating scheme, the service life of a compressor is short, and coil pipe temperature fluctuation is large. In order to achieve the purpose, the heat storage control method comprises the steps that when aprediction time point is reached, based on a pre-established scoring system, the probability score of starting a heating mode of an air conditioner at the next prediction starting moment is calculated; when the probability score is larger than a set threshold value, the compressor is controlled to run at a first heat storage frequency, and an outdoor draught fan is controlled to run; In the running process of the compressor, the coil pipe temperature of an indoor heat exchanger is detected; the coil pipe temperature and a first preset temperature are judged; and based on a judgment result, theopening and closing of an outdoor draught fan and / or the running 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 coil pipe temperature in the air conditioner heat storage process is reduced, and 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 ...
