Abstract

The invention discloses an air conditioner and a self-cleaning control method thereof, belonging to the technical field of air conditioners. The control method includes: obtaining the coil temperature in the frosting stage of the self-cleaning mode of the air conditioner; adjusting the fan speed based on the temperature comparison result between the coil temperature and the frosting critical temperature and the change in the coil temperature; and adjusting the fan speed according to the coil temperature The amount of change determines the compensation amount of the speed. The air-conditioning self-cleaning control method provided by the present invention can adjust the speed of the fan in the frosting stage based on the temperature comparison result of the coil temperature and the frost critical temperature and the variation of the coil temperature, which is different from the existing fan shutdown or fixed The speed of operation, the dynamically adjusted fan speed can better match the temperature change inside the air conditioner, so as to use the changing speed to speed up the frosting rate in the frosting stage and increase the actual amount of frosting, so as to ensure the actual cleaning effect of the self-cleaning mode .

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...
