Abstract

The present invention provides an air conditioner defrosting control method, device, storage medium and air conditioner. The method includes: when the air conditioner meets the defrosting conditions when the air conditioner is in heating operation, judging that the outdoor heat exchange The degree of frosting of the device is the first degree of frosting or the second degree of frosting; wherein, the thickness of the frost layer of the first degree of frosting is smaller than the thickness of the frost layer of the second degree of frosting; if it is determined that the outdoor replacement If the frosting degree of the heater is the first frosting degree, the air conditioner is controlled to defrost in the first defrosting manner, and if it is judged that the frosting degree of the outdoor heat exchanger is the second frosting degree, the The air conditioner defrosts in the second defrosting mode; the first defrosting mode and the second defrosting mode are four-way valve non-reversing defrosting, and the air conditioner maintains a heating state during defrosting. The solution provided by the present invention can perform non-reversing defrosting in different ways according to different frosting degrees, and can take into account both the defrosting effect and room comfort.

Description

technical field [0001] The invention relates to the field of control, in particular to an air conditioner defrosting control method, device, storage medium and air conditioner. Background technique [0002] Heat pump air conditioners provide heat to the room during the cold season. When the heat pump air conditioner runs for a period of time, the heat exchanger of the outdoor unit will often frost, which will affect the heat exchange efficiency of the air conditioner. Air conditioner defrosting is needed to solve this problem. [0003] The existing defrosting method mainly judges that when the outdoor unit is frosted to a relatively thick degree, which seriously affects the indoor heating capacity, switch from the heating mode to the cooling mode, so that the high-temperature gas of the compressor directly enters the outdoor unit, thereby realizing defrosting. However, in this way, the indoor heating capacity will drop significantly before defrosting begins. During the de...
