Abstract

The invention provides an air conditioner defrosting control method and device, a storage medium and an air conditioner. The method comprises the steps: when the heating operation time is longer than the preset time, according to whether the indoor temperature and a reduction value of the indoor temperature during last defrosting meet a second preset condition or not and whether the temperature of an outdoor heat exchanger meets a first preset condition or a third preset condition or not, determining whether a defrosting mode is started or not; when the second preset condition is met, determining whether a defrosting mode is started or not according to whether the temperature of the outdoor heat exchanger meets the third preset condition or not; if the temperature of the outdoor heat exchanger meets the third preset condition, determining to start the defrosting mode, and if not, keeping heating operation; when the second preset condition is not met, determining whether a defrosting mode is started or not according to whether the temperature of the outdoor heat exchanger meets the first preset condition or not; and if the temperature of the outdoor heat exchanger meets the first preset condition, determining to start the defrosting mode, and if not, keeping heating operation. According to the scheme provided by the invention, the defrosting mode can be started at the proper time, and the defrosting time is shortened.

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...
