Control method and system for fan of air conditioner as well as air conditioner

Abstract

The present invention relates to an air conditioner fan control method, system and air conditioner, wherein, the control method includes acquiring the current wind gear of the fan in the air conditioner; acquiring a parameter representing the clogging degree of the filter component in the air conditioner; and judging the clogging degree of the filter component Whether the parameter exceeds the allowable threshold under the current wind gear, if yes and the current wind gear is not the highest wind gear, increase the current wind gear by one gear. This control method can increase the air volume by increasing the windshield when the filter parts of the air conditioner are seriously blocked, so as to prevent the air conditioner from entering the anti-freezing, anti-high temperature or compressor protection state, thereby ensuring the cooling and heating effect of the air conditioner. Improve the comfort of use; but also ensure the reliability of the compressor, so as to improve the service life of the whole machine.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner fan control method, system and air conditioner. Background technique [0002] With the improvement of people's requirements for air quality, air conditioners with filtering function appear continuously on the market. As the air conditioner's filter screen increases with the increase of the air conditioner's operating time, more and more dust will accumulate, which will directly make the air conditioner The air volume decreases, which in turn affects the cooling and heating effects, and even causes air conditioner protection in severe cases. Traditional air conditioners automatically control the working gear of the indoor fan according to the temperature difference between the target temperature and the indoor environment, without considering the attenuation of the air volume caused by the dirty filter, which will affect the cooling and heating effect o...

[0002] With the improvement of people's requirements for air quality, air conditioners with filtering function appear continuously on the market. As the air conditioner's filter screen increases with the increase of the air conditioner's operating time, more and more dust will accumulate, which will directly make the air conditioner The air volume decreases, which in turn affects the cooling and heating effects, and even causes air conditioner protection in severe cases.

Traditional air conditioners automatically control the working gear of the indoor fan according to the temperature difference between the target temperature and the indoor environment, without considering the attenuation of the air volume caused by the dirty filter, which will affect the cooling and heating effect of the air conditioner, and sometimes even cause the compressor to fail. shutdown
