Abstract:
A method and device for defrosting an air conditioner. The method comprises the following steps: detecting a refrigerant pressure of a heat exchange; obtaining, according to the detected refrigerant pressure of the heat exchange, a corresponding saturation temperature; obtaining an ambient dew point temperature; and when the corresponding saturation temperature is less than 0°C and less than the ambient dew point temperature, controlling the air conditioner to enter a defrost mode. The method can ensure timely defrosting when frost is formed, prevent defrosting when no frost is formed, extending a service life of an air conditioner.
