Abstract

The invention provides an air conditioner defrosting control method and device, a storage medium and an air conditioner. The air conditioner defrosting control method comprises the steps that whether the frosting degree of an outdoor heat exchanger is a first frosting degree or a second frosting degree is judged under the condition that the air conditioner operates in a heating mode and when the air conditioner meets a defrosting condition; the thickness of a frost layer of the first frosting degree is smaller than that of the frost layer of the second frosting degree; if it is judged that the frosting degree of the outdoor heat exchanger is the first frosting degree, the air conditioner is controlled to perform defrosting in a first defrosting mode, and if it is judged that the frosting degree of the outdoor heat exchanger is the second frosting degree, the air conditioner is controlled to perform defrosting in a second defrosting mode; and the first defrosting mode and the second defrosting mode are four-way valve non-reversing defrosting, and the air conditioner is kept in a heating state during defrosting. According to the scheme, different modes of non-reversing defrosting can be carried out according to different frosting degrees, and the defrosting effect and the room comfort can be both balanced.

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...
