Abstract

The present invention provides a multi-connected air conditioner and its defrosting control method, device, and storage medium. The method includes: before the multi-connected air conditioner defrosts, the indoor unit in a preset state is stored before defrosting. Thermal control; when the multi-connected air conditioner is defrosting, defrosting control is performed on each indoor unit according to the state of each indoor unit; the preset state includes: shutdown state, power-on and shutdown state when it reaches the temperature point, and / or Or power on and there is no one in the room. The solution provided by the invention can accelerate the defrosting process and reduce the defrosting time.

Description

technical field [0001] The invention relates to the field of control, in particular to a multi-connected air conditioner and its defrosting control method, device and storage medium. Background technique [0002] The multi-split unit is more and more popular with users because of its installation and use flexibility and intelligence. The air-source multi-split unit is the same as the conventional air-source air conditioner. When the outdoor unit frosts in the heating season, it needs to switch to the cooling mode. During defrosting, the room cannot be heated during the defrosting period, and the defrosting time is long, which will affect the user's comfort, and cause the indoor air temperature to drop, the room temperature to fluctuate, and the user's comfort experience is poor. Contents of the invention [0003] The main purpose of the present invention is to overcome the defects of the above-mentioned prior art, and provide a multi-connected air conditioner and its defro...
