Abstract

The invention provides an air conditioner defrosting control method, device, storage medium and air conditioner. The method includes: when the heating operation time is greater than the preset time, according to the indoor temperature and whether the lower value of the indoor temperature during the last defrosting meets the second Whether the preset condition and the temperature of the outdoor heat exchanger meet the first preset condition or the third preset condition, determine whether to enter the defrosting mode; when the second preset condition is met, according to whether the temperature of the outdoor heat exchanger meets the third preset condition Set the conditions to determine whether to enter the defrosting mode. If the temperature of the outdoor heat exchanger meets the third preset condition, then determine to enter the defrosting mode, otherwise, keep the heating operation; Whether the temperature of the outdoor heat exchanger satisfies the first preset condition determines whether to enter the defrosting mode, if the temperature of the outdoor heat exchanger meets the first preset condition, then determines to enter the defrosting mode, otherwise, keeps the heating operation. The solution of the invention can select a suitable time to enter the defrosting mode, and shorten the defrosting time.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on January 28, 2021, with the application number 202110118342.3, and the title of the invention is "A method, device, storage medium and air conditioner for controlling defrosting of an air conditioner", the entire content of which Incorporated in this application by reference. technical field [0002] 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 [0003] Heat pump air conditioners have attracted attention because of their economical and efficient features, but they seriously affect the performance of the system due to frost formation during use in winter. The indoor temperature will drop during the defrosting process, and users often feel uncomfortable. The longer the defrosting time, the greater the indoor temperature drop caused b...
