Self-cleaning control method of outdoor heat exchanger of variable-frequency air conditioner and air conditioner

Abstract

The invention discloses a self-cleaning control method of an outdoor heat exchanger of a variable-frequency air conditioner and the air conditioner. The method comprises the following steps that (1),the current outdoor environment temperature T-out is detected, moreover, whether the current outdoor environment temperature meets the condition of entering the self-cleaning control of the outdoor heat exchanger or not is judged, if yes, the step (2) is executed, otherwise, the self-cleaning control of the outdoor heat exchanger is not executed; (2), the outdoor heat exchanger is controlled for frosting; (3), frost formed by the outdoor heat exchanger is melted, and self-cleaning control is completed. According to the self-cleaning control method of the outdoor heat exchanger of the variable-frequency air conditioner, a large amount of low-density frost is formed quickly in a short time through the outdoor heat exchanger, then the frost is quickly melted, and then dust attached to the outdoor heat exchanger is washed away.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a self-cleaning control method for an outdoor heat exchanger of an inverter air conditioner and an air conditioner. Background technique [0002] Whether the air conditioner is running or standing still, dust will adhere to the indoor and outdoor heat exchangers. For the consideration of indoor air quality and heat exchange efficiency of indoor heat exchangers, many brands of air-conditioning products have applied the self-cleaning control method of indoor heat exchangers for the cleaning of indoor heat exchangers. The outdoor heat exchanger is located outdoors, there is no air quality problem caused by the operation of the air conditioner, and its cleanliness is easily overlooked by people. However, due to the external environment, the outdoor heat exchanger is more likely to adhere to more and thicker dust. The heat transfer performance of the air conditioner has a gr...
