Embodiment 1

[0072] First refer to figure 1 and figure 2 , to describe the heat storage mode control method of the air conditioner of the present invention. in, figure 1 It is a flow chart of the heat storage mode control method of the air conditioner of the present invention; figure 2 It is a logic diagram of the heat storage mode control method of the air conditioner of the present invention.

[0073] Such as figure 1 As shown, in order to solve the problems of short compressor life and large coil temperature fluctuations in the existing preheating scheme, the air conditioner of the present invention includes a compressor, a throttling element, an outdoor heat exchanger, an outdoor fan, and an indoor heat exchanger and an indoor fan, wherein the compressor is an inverter compressor, and the outdoor fan is an AC fan. The main steps of the heat storage mode control method of the air conditioner include:

[0074] S101. When the predicted time point is reached, based on the pre-estab...

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 a preheating scheme. The control method comprises the steps that a probability score of starting heating at a next predicted startup moment is calculated based on a scoring system; when the probability score is higher than a set threshold, the predicted startup moment is corrected based on time correction parameters; heat storage timeis determined based on outdoor environment temperature; a heat storage starting moment is calculated based on the corrected predicted startup moment and the heat storage time; when the heat storage starting moment is reached, a compressor and an outdoor fan are 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 is detected at the interval of set time and compared with the first preset coil temperature; and the operating frequency of the compressor and the opening and closing of the outdoor fan are adjusted based on the judgment result. According to the control method, the service life of the compressor can be prolonged, and the fluctuation of the coil temperature 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...
