Problems solved by technology

Among them, in the defrosting stage, the air conditioner is heating and running. In most air conditioner products, the defrosting temperature of the heat exchanger is generally controlled solely by the compressor. For example, when the temperature of the heat exchanger is high, the frequency of the compressor is only reduced. , but such an adjustment method is likely to cause misjudgment, resulting in unnecessary adjustment of the compressor and affecting the stability of the compressor operation

[0055] refer to figure 2 , the first embodiment of the air-conditioning control method of the present invention is proposed, and the air-conditioning control method includes:

[0056] Step S10, when the air conditioner is in the self-cleaning mode, control the cooling operation of the air conditioner so that the air conditioner can complete condensation and frost;

[0057] The self-cleaning mode is an operating mode of the air conditioner. In the self-cleaning mode, the air conditioner will adjust the operation of its own compressor, fan, four-way valve, throttling device and other components to clean the heat exchanger. Specifically, the operating stages of the air conditioner in the self-cleaning mode may specifically include a condensation stage, a frosting stage, and a defrosting stage in sequence. Among them, during the condensation stage and the frosting stage, the air conditioner is in cooling operation, and the heat exchanger first forms condensed water to cover the ...

Abstract

The invention discloses a control method of an air conditioner, and further discloses a control device of the air conditioner, the air conditioner and a readable storage medium. The method comprises the following steps of controlling the air conditioner to run in a refrigeration mode so as to complete condensation and frosting when the air conditioner is in a self-cleaning mode; controlling the air conditioner to run in a heating mode, and acquiring the current coil temperature of a heat exchanger as the first coil temperature; and adjusting the frequency of a compressor and the rotating speedof a fan of the heat exchanger according to the first coil temperature. With the air conditioner, the control method and control device thereof and the readable storage medium, the running stabilityof the compressor can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device, an air conditioner and a readable storage medium. Background technique [0002] Most of the existing air conditioners use tube-fin heat exchangers, and pollutants such as dust in the air are easy to adhere to the fins, and will continue to accumulate into dirt with the use of the air conditioner. The formation of dirt will increase the heat transfer resistance of the fins, reduce the heat transfer efficiency of the heat exchanger, and at the same time nourish bacteria and affect air quality. Therefore, the heat exchanger needs to be cleaned regularly during the use of the air conditioner, and the self-cleaning function of the air conditioner came into being. [0003] The self-cleaning process of the air conditioner generally includes steps such as condensation, frosting, and defrosting. Among them, i...
