Document Type and Number:
WIPO Patent Application WO/2020/233116
Kind Code:
A1
Abstract:
An air conditioner defrosting control method, which aims to solve the problem that the existing air conditioners have a poor way of detecting the frosting condition of outdoor coils, and the defrosting efficiency of the existing defrosting methods is low. Therefore, the defrosting control method includes the following steps: determining the frosting degree of each group of coils, so that the air conditioner can accurately and comprehensively judge the frosting condition of the whole outdoor unit; according to the frosting degree of each group of coils, controlling the flow of refrigerant in each group of coils, that is, the defrosting requirements of each group of coils can be judged according to the frosting degree of each group of coils, so that the flow of refrigerant in each group of coils is controlled to adapt to the frosting degree of each group of coils, thereby effectively shortening the defrosting time of the air conditioner, and then greatly improving the defrosting efficiency of the air conditioner.
