Abstract

The invention discloses an air conditioner and a defrosting method thereof. The defrosting method comprises the following steps: when the air conditioner runs in a heating mode and the outdoor environment temperature is smaller than a preset temperature, acquiring any one of the air pressure of an outdoor heat exchanger, the air speed of the outdoor heat exchanger, the current of an outdoor fan and the rotating speed of the outdoor fan; judging the frosting degree of the outdoor heat exchanger according to any one of the air pressure of the outdoor heat exchanger, the air speed of the outdoor heat exchanger, the current of the outdoor fan and the rotating speed of the outdoor fan; according to the frosting degree, controlling the air conditioner to perform defrosting by selecting a defrosting mode corresponding to the frosting degree. According to the method, a corresponding defrosting mode is selected for defrosting according to the frosting degree of the outdoor heat exchanger, so the aim of intelligent defrosting is realized, the defrosting frequency is reduced, the heating capability of the air conditioner is improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting method and an air conditioner. Background technique [0002] The outdoor unit of an air-cooled air conditioner is generally composed of a refrigeration system composed of a condenser, pipeline components, compressors, and valves, an air duct system composed of fans, blades, and grilles, and a control system. Among them, the heat exchange of the condenser is completed by relying on the air provided by the fan to flow through the condenser to take away the heat. The condenser is generally composed of copper tubes and heat dissipation fins attached to the surface of the copper tubes. The function of the heat dissipation fins is to increase the heat transfer area and improve the heat transfer efficiency. [0003] Usually, the outdoor unit of an air conditioner is installed outdoors. When the outdoor ambient temperature is relatively low and the...
