Air conditioner control method

Abstract

The invention discloses a method for controlling an air conditioner. The method is carried out during the defrosting operation and / or in the early stage of the reentering heating operation after finishing defrosting; according to the judgment of the room temperature, the directions of a left blade and a right blade are controlled by utilizing a result detected through a human induction sensor in order that the swinging directions of the left blade and the right blade point to a peopleless region judged by a detection result. During the defrosting, an indoor fan can operate at high rotational speed, improve heat-exchange efficiency in the indoor side and shorten defrosting time; and in the early stage of reentering the heating operation after finishing defrosting, the indoor fan can operate at high rotational speed and improve the heating effect, avoid cold wind from directly blowing on people and improve comfortableness.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner control method. Background technique [0002] In the existing cabinet-type air conditioner, in order to prevent cold air from blowing out of the air outlet of the indoor unit during defrosting operation, as disclosed in Chinese patent CN200510014420, it generally adopts the initial stage of re-entering the room heating operation during defrosting and after defrosting is completed. , the method of reducing the speed of the indoor fan or stopping the indoor fan. [0003] Although the above method can effectively prevent cold air from blowing out from the indoor unit during defrosting, the indoor fan is decelerated or stopped at this time (such as figure 1 , shown in 2), will bring the following disadvantages: [0004] 1. During the defrosting period, the heat exchange efficiency of the indoor side during the defrosting process is reduced, and the defrosting time...

AI Technical Summary

Problems solved by technology

[0004] 1. During the defrosting period, the heat exchange efficiency of the indoor side during the defrosting process is reduced, and the defrosting time is prolonged;

[0005] 2. After defrosting is completed, it enters the initial stage of heating operation again, and the heating effect is not good

[0006] However, if the speed of the indoor fan is not reduced or the indoor fan is stopped, the low-temperature air in the indoor unit will be blown directly onto the user, making people feel cold and reducing comfort.
