Snow cover prevention control method for fan of outdoor unit of air conditioner

Abstract

The invention discloses a snow cover prevention control method for a fan of an outdoor unit of an air conditioner. The method comprises the following steps: judging whether the function of snow cover prevention is opened or not when the snow falls; if the function of snow cover prevention is not opened, stopping the function of snow cover prevention; if the function of snow cover prevention is opened, judging whether the outdoor temperature is lower than the set snow removing temperature or not; if the outdoor temperature is higher than the set snow removing temperature, stopping the function of snow cover prevention; if the outdoor temperature is lower than the set temperature removing temperature, judging whether the outdoor unit is in the stop state or not; if the outdoor unit is in the running state, stopping the function of snow cover prevention; and if the outdoor unit is in the stop state, carrying out the function of snow cover prevention. The control logic of applying the function of snow cover prevention is added on the outdoor unit of the air conditioner, therefore, an outdoor switch used for snow cover prevention is added, and the snow is removed by the fan which automatically runs for two minutes in every 30 minutes when the outdoor unit stops and the function of snow cover prevention is opened during snowing.
