Abstract

The invention discloses an air conditioner and a self-cleaning control method thereof, and belongs to the technical field of air conditioners. The control method comprises the following steps: acquiring coil pipe temperature of a frosting stage of an air conditioner running a self-cleaning mode; and adjusting the rotating speed of a fan based on the temperature comparison result of the coil pipe temperature and the defrosting critical temperature, wherein the adjustment rate of the rotating speed is determined according to the temperature comparison result. The self-cleaning control method ofthe air conditioner can adjust the rotating speed of the fan in the defrosting stage based on the temperature comparison result of the coil pipe temperature and the defrosting critical temperature, the mode is different from the existing operation mode of stopping the fan or fixing the rotating speed, the dynamically-adjusted rotating speed of the fan can be better matched with the temperature change inside the air conditioner, so that the frosting rate in the frosting stage is accelerated through the changed rotating speed, the practical frosting amount is improved, and the practical cleaningeffect of the self-cleaning mode is ensured.

Description

technical field

[0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a self-cleaning control method thereof. Background technique

[0002] When the air conditioner is running in the cooling or heating mode, the air in the external environment enters the inside of the body along the air inlet, and is blown back into the external environment through the air outlet after the heat exchange fins exchange heat. In this process, all the air in the air Impurities such as dust and large particles will also enter the interior of the indoor unit along with the air intake. Although the dust filter installed at the air inlet of the air conditioner can filter most of the dust and particles, there will still be a small amount of tiny dust It cannot be completely blocked and filtered. With the long-term use of the air conditioner, these dusts will gradually deposit and adhere to the surface of the heat exchange fins. Due to the poo...
