The invention discloses an automobile heat pump air conditioner HVAC structure which comprises a shell, a single air duct is arranged in the shell and comprises an air inlet duct and a heat exchange air duct which are sequentially communicated, an air blower is arranged in the air inlet duct, the heat exchange air duct is linearly arranged, and the air inlet duct is communicated with the heat exchange air duct. A first in-vehicle heat exchanger, an all-pass throttle valve, a second in-vehicle heat exchanger, a PTC heater and an air distribution mechanism are sequentially arranged in the heat exchange air duct, the first in-vehicle heat exchanger and the second in-vehicle heat exchanger are both used for cooling or heating air in a passenger compartment, and the all-pass throttle valve is used for expansion throttling and controlling the flow of a refrigerant. The internal air duct structure and space arrangement of the HVAC are simplified, a warm air core body and a temperature air door are omitted, installation is flexible, and air resistance is reduced.
本发明公开了一种汽车热泵空调HVAC结构,包括壳体,所述壳体内设有单个风道,所述风道包括依次连通的进风风道和换热风道,所述进风风道内设有鼓风机,所述换热风道呈直线型排列,所述换热风道内依次设置有第一车内换热器、全通节流阀、第二车内换热器、PTC加热器和分风机构,所述第一车内换热器和所述第二车内换热器均用于对乘员舱空气进行冷却或加热,所述全通节流阀用于膨胀节流以及控制制冷剂的流量。本发明简化了HVAC的内部风道结构和空间布置,省去暖风芯体和温度风门,安装灵活且减小风阻。
