One way to drain the condensate is by pumping the condensate out through a water pump.
However, when the temperature of the heat exchanger is lower than 0 ℃, condensed water on the heat exchanger is frozen, in order to ensure the normal operation of the heating mode of the air conditioner, the air conditioner needs to operate the defrosting mode to melt the ice into an ice-water mixture which falls on the chassis of the external machine of the air conditioner, and finally the ice-water mixture is converted into water to be pumped out by the water pump.
