Description

Air conditioner and control method thereof Technical Field The invention belongs to the technical field of air conditioners, and particularly provides an air conditioner and a control method thereof. Background With the improvement of the living standard of people, the requirements of people on the air quality in the environment are gradually improved. In order to improve the indoor air quality, a purification module is generally added in the air conditioner to filter, purify and sterilize the indoor air, so as to improve the indoor air quality. And as the service time of the air conditioner purifying module is continuously increased, the purifying capacity of the purifying module is gradually weakened, the indoor air is not better purified, and the air quality is also poorer and poorer. If the purification module is used continuously, secondary pollution is easily caused, and the indoor air quality is greatly reduced. Therefore, there is an urgent need for an air conditioner capable of solving the above-mentioned problems.
