Embodiment Construction

[0033] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0034] Air conditioners perform functions such as cooling / heating cycles or dehumidification through compressors, condensers, expansion valves, and evaporators, which can adjust the indoor environment and improve the comfort of the indoor environment. A refrigeration cycle includes a series of processes such as those involving compression, condensation, expansion, and evaporation, and supplies refrigerant to air that has been conditioned and heat-exchanged.

[0035] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser, and the condenser condenses the compressed refrigerant into a liquid state, and the heat is released...

Abstract

The invention discloses an air conditioner self-cleaning control method and device, a storage medium, and an air conditioner. The air conditioner self-cleaning control method is characterized in that the air conditioner comprises a low-voltage protection switch, and the control method comprises the steps that a target self-cleaning mode is determined in response to a self-cleaning instruction; a to-be-cleaned target heat exchanger is determined according to the target self-cleaning mode; a coil pipe temperature of the to-be-cleaned target heat exchanger is obtained; and in the frosting stage, a fan corresponding to the to-be-cleaned target heat exchanger is controlled to stop running, the frequency of a compressor and the rotating speed of a running fan are controlled according to the coil pipe temperature of the to-be-cleaned target heat exchanger and a saturation temperature corresponding to a refrigerant low-voltage protection threshold value of the low-voltage protection switch, and the opening of a throttling element is controlled according to an actual superheat degree of the air conditioner. For the air conditioner provided with the low-voltage protection switch, it can be ensured that the refrigerant pressure in a system meets the low-voltage requirement in the self-cleaning process through the method, and the problem that self-cleaning cannot be completed due to shutdown caused by starting of the low-voltage protection switch is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner self-cleaning control method, an air conditioner self-cleaning control device, a computer storage medium and an air conditioner. Background technique [0002] For the self-cleaning control mode of the air conditioner, its essence is to frost and defrost the heat exchanger. Among them, in order to make the frosting of the heat exchanger smooth, the fan on the frosting side is usually stopped. However, for an air conditioner equipped with a low-voltage protection switch, when the fan stops, the low-voltage protection switch is activated due to the low pressure of the refrigerant in the air-conditioning system, so that the self-cleaning operation cannot continue. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is...
