no. 1 example

[0065] refer to figure 2 , figure 2 It is the first embodiment of the control method of the air conditioner of the present invention, and the control method of the air conditioner includes the following steps:

[0066] Step S10, after the air conditioner operates in cooling mode, regularly acquire the current of the compressor in the air conditioner, and the compressor is a fixed-frequency compressor;

[0067] In this embodiment, the execution subject is an air conditioner. The air conditioner is provided with a compressor, and the compressor is a fixed-frequency compressor. The air conditioner is equipped with a current detection device for detecting the current of the compressor. After the air conditioner operates in cooling mode, the compressor runs at a fixed frequency, and the air conditioner activates the current detection device to obtain the current of the compressor.

[0068] The air conditioner can regularly obtain the current of the compressor detected by the ...

Abstract

The invention discloses an air conditioner control method which comprises the following steps that after an air conditioner runs in a refrigeration mode, the current of a compressor in the air conditioner is obtained regularly, and the compressor is a fixed-frequency compressor; when the current is larger than the refrigeration rated current, the current coil pipe temperature of an indoor heat exchanger is obtained; a current interval where the current is located is determined, and a target coil pipe temperature corresponding to the current interval is determined; and when the current coil pipe temperature is larger than the target coil pipe temperature, the air speed of an indoor fan in the air conditioner is reduced. The invention further discloses the air conditioner and a computer readable storage medium. The air conditioner is high in refrigeration stability.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner, a control method thereof, and a computer-readable storage medium. Background technique [0002] When the fixed-frequency air conditioner is in cooling mode, the power of the fixed-frequency compressor will increase due to the high ambient temperature. In addition, since the outdoor heat exchanger is located outdoors, the outdoor heat exchanger will be dirty and blocked, and the outdoor heat exchanger will be oxidized and damaged, thereby causing the heat exchange efficiency of the outdoor heat exchanger to decrease. In the case of low heat exchange efficiency, the compressor needs to further increase the power for cooling, which will trigger the overload protection of the compressor, causing the compressor to stop, causing the air conditioner to exit the cooling mode, and the cooling stability of the air conditioner is poor. Contents of the ...
