Abstract

The invention discloses a control method of an air conditioner, and the control method of the air conditioner can reduce frosting. Specifically, if fins of an outdoor heat exchanger of the air conditioner are hydrophobic coatings, the control method comprises the following steps of: enabling water on the fins of the heat exchanger to form water drops on the hydrophobic coatings when the air conditioner operates in a heating mode, driving a fan of an outdoor unit to reversely rotate, enabling air to blow towards the heat exchanger, and enabling water on the fins of the heat exchanger to drop under action of air. If fins of the outdoor heat exchanger of the air conditioner are hydrophilic coatings, the control method comprises the following steps of: detecting whether an outdoor temperatureis lower than a preset temperature or not when the air conditioner operates in a heating mode, and driving the fan of the outdoor unit to reversely rotate if the outdoor temperature is lower than thepreset temperature; otherwise, driving the fan of the outdoor unit to positively rotate. The control method of the air conditioner solves the problem that the air conditioner is high in frosting speedin winter, and increases heating capacity of the air conditioner when the temperature in winter is low, so that a room reaches a temperature set by a user more quickly, and therefore, user experienceis improved.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to the field of a frost-free air conditioner. Background technique [0002] When the air conditioner is heating, the outdoor heat exchanger mainly plays the role of evaporation, the surface temperature will be lower than the dew point temperature of the air, and a large amount of condensed water will be generated, and as the weather changes, the outdoor temperature will drop, and the surface temperature of the outdoor heat exchanger will At this time, the water in the heat exchanger will turn into a frost layer or even an ice layer. The appearance of the frost layer or ice layer will increase the wind resistance, and due to the increase of the wind resistance, the surface temperature of the heat exchanger will further increase. If it is lowered, the frosting will be accelerated, and the heating capacity will be greatly reduced as the frost layer becomes thicker, which wil...
