    • An air conditioning system for a vehicle is provided with a heat pump circulation path through which a refrigerant body is circulated through a compressor. The heat pump circulation path is provided with a condenser unit, an expansion valve, a first evaporator, a heater, and a second evaporator. The heat pump circulation path is also provided with a bypass means which, in heating operation, bypasses a main condenser for constituting the condenser unit and connects the heater and a gas-liquid separation-type refrigerant body containing section. The configuration provides effects which minimize an increase in the number of dedicated parts required only in a heating mode and which, by effectively utilizing the system in a cooling mode, prevents a reduction in the air conditioning performance caused by the shortage of the refrigerant body.
    • 一种车辆空调系统具有热泵循环路径,制冷剂体通过该循环路径通过压缩机循环。 热泵循环路径设置有冷凝器单元,膨胀阀,第一蒸发器,加热器和第二蒸发器。 热泵循环路径还设置有旁路装置,其在加热操作中绕过用于构成冷凝器单元的主冷凝器,并且连接加热器和气液分离型制冷剂本体容纳部。 该结构提供了使加热模式中仅需要的专用部件的数量增加最小化的效果,并且通过在冷却模式下有效地利用该系统,可以防止由于制冷剂体的不足引起的空调性能的降低。
