Abstract

A air source heat pump with additional frost-proof heat exchanging tube mainly includes a compressor, a condenser for heating, a throttling device, an evaporator absorbing heat from outdoor air source, a gas-liquid separator, a connecting tube and a switching valve and etc, which is characterized in that the windward side of the evaporator has an additional line of frost-proof heat exchange tubes for cooling refrigerant and auxiliary heating of the evaporator. The heat exchange tubes on the frost-proof heat exchange tube and the evaporator for evaporating the original refrigerant share the same fins. The frost-proof heat exchange tube connects to the position between a refrigerant outlet of the condenser for heating and the inlet of the throttling device. The technology can be applied in a single air source circulation heat pump, a separated double heat source circulation heat pump, a multipurpose heat pump and etc. The device takes advantage of the thermal refrigerant of 50 degrees released from the condenser to exchange heat in the frost-proof heat exchange tube with the evaporator and improves the wind temperature of the evaporator and transfers heat by means of the evaporator fins, thereby effectively the frosting time and extent of the air source heat pump is reduced and frosting time is prolonged. So, the frosting area of the heat pump moves northward, the annual frosting period shortens and the heat pump efficiency is increased in winters.
