| Abstract: | The frosting performance of air-source heat pump water heater is expounded.The defrost characteristic of heat pump water heater is analyzed,which is differentfrom air conditioner.A new defrost method based on comprehensive evaluation according to the temperature of the evaporator and condenser is proposed.This method judge whether the outdoor evaporator was frosted by the temperature difference between the condenser and water,and judge whether the outdoor evaporator was defrosted by its coil temperature. |
