Abstract

The embodiment of the invention discloses a defrosting method of an air conditioner and the air conditioner, and relates to the technical field of air conditioners. The defrosting method of the air conditioner solves the problem that indoor temperature decreases when an air conditioner is defrosted in winter, and the user experience is low. The specific scheme of the method comprises the followingsteps: acquiring first liquid pipe temperature of a first heat exchanger and second liquid pipe temperature of a second heat exchanger after heating time reaches set threshold; if the first liquid pipe temperature is less than first defrosting temperature threshold, and the second liquid pipe temperature is beyond or equal to the second defrosting temperature threshold, controlling the first heatexchanger to defrost; controlling a first fan to stop running; controlling the second heat exchanger to keep heating; and controlling a second fan to run. The method in the embodiment is applicable to defrosting process of the air conditioner.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of air conditioners, and in particular, to an air conditioner defrosting method and the air conditioner. Background technique [0002] When the air conditioner is heating at low temperature in winter, the surface temperature of the heat exchanger of the outdoor unit is low. When the temperature is lower than the outdoor air temperature, the water vapor in the outdoor air will condense on the surface of the heat exchanger, so that The refrigerant absorbs heat. However, if the outdoor air temperature is below zero degrees Celsius, the water vapor in the air will condense into frost on the surface of the heat exchanger. As the heating process continues, the frost layer on the surface of the heat exchanger will continue to thicken, making the heating effect of the air conditioner worse. Therefore, when the frost layer accumulates to a certain thickness, the air conditioner needs to be def...
