The invention belongs to the technical field of air conditioners, and particularly relates to a defrosting control method for an air conditioner. The invention aims to solve the problems that a mode that an existing air conditioner detects the frosting condition of an outdoor coil pipe is poor, and the defrosting efficiency of an existing defrosting mode is low. For this purpose, the defrosting control method comprises the following steps that a frosting degree of each group of coil pipes is determined, so that the air conditioner can accurately and comprehensively judge the frosting conditionof a whole outdoor unit; and a refrigerant flow in each group of the coil pipes is controlled according to the frosting degree of each group of the coil pipes. According to the defrosting control method for the air conditioner, the defrosting requirements of each group of the coil pipes can be judged according to the frosting degree of each group of the coiled pipes, so that the refrigerant flowin each group of the coil pipes can be controlled, the refrigerant flow in each group of coil pipes is matched with the frosting degree of each group of coil pipes, so that the defrosting time of theair conditioner is effectively shortened, and the defrosting efficiency of the air conditioner is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a defrosting control method for an air conditioner. Background technique [0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment. In order to maintain a comfortable ambient temperature, air conditioners have become an essential device in people's lives. Generally, an air conditioner includes an indoor unit, an outdoor unit, and a circulation loop for connecting the indoor unit and the outdoor unit. The refrigerant in the air conditioner continuously exchanges heat between the outdoor unit and the indoor unit through the circulation loop, thereby achieving the effect of changing the room temperature. . Take the heating operation of the air conditioner as an example, the coil of the outdoor unit is always in a low temperature state, and the outdoor temperatur...
