Abstract

The invention relates to an air conditioner self-cleaning control method. The air conditioner comprises a refrigerant circulation loop composed of a compressor, a four-way valve, an outdoor heat exchanger, a throttling component, a stop valve, an indoor heat exchanger and a gas-liquid separator, wherein temperature sensors are respectively arranged on the compressor, the outdoor heat exchanger andthe indoor heat exchanger. The control method comprises a preheating process, a frosting process, a drying process I, a drying process II and a drying process III. According to the air conditioner self-cleaning control method, the cleaning effect of the air conditioner heat exchanger can be effectively enhanced, high-temperature sterilization can be achieved, and the heat exchanger can be kept dry; and in addition, the liquid return amount of the system can be controlled by controlling the exhaust superheat degree, the dilution of the liquid refrigerant to the oil is reduced, and the servicelife of the compressor is prolonged.

Description

technical field [0001] This patent relates to an air conditioner control technology, in particular to an air conditioner self-cleaning control method. Background technique [0002] When the air conditioner is used for cooling for a long time, the condensed water on the surface of the heat exchanger cannot be dried in time, and the humid environment will breed bacteria, mold, etc., which will not only produce peculiar smell but also affect human health; in addition, if the air conditioner is left unused for a long time, A large amount of dust will accumulate on the surface of the heat exchanger, which will increase the air flow resistance, which not only affects the cooling and heating effect, but also affects the indoor air quality. Therefore, in order to solve the problems of humidity inside the air conditioner and dust accumulation in the heat exchanger, a self-cleaning function is proposed. [0003] The self-cleaning function of some air conditioners is to use the conden...
