Disclosed in the present invention is a vehicle heat pump system capable of improving dehumidification performance by increasing a flow rate of refrigerant toward an evaporator during heating and dehumidification modes. The vehicle heat pump system includes: a bypass line branching between a first expansion valve and an outdoor heat exchanger and bypassing the outdoor heat exchanger and an evaporator; a first refrigerant flow control valve for adjusting an opening degree between the bypass line and a refrigerant line facing the outdoor heat exchanger; a dehumidification line branched between the first expansion valve and the first flow control valve to supply refrigerant to the evaporator; and a control unit for controlling an amount of refrigerant supplied to the dehumidification line according to an outdoor air temperature or a compressor RPM.
在本发明中公开了一种车辆热泵系统，该车辆热泵系统能够通过在加热和除湿模式期间增大制冷剂朝向蒸发器的流量来提高除湿性能。车辆热泵系统包括：旁通管线，该旁通管线在第一膨胀阀与室外热交换器之间分支出并且绕过室外热交换器和蒸发器；第一制冷剂流量控制阀，该第一制冷剂流量控制阀用于调节旁通管线与朝向室外热交换器的制冷剂管线之间的开度；除湿管线，该除湿管线在第一膨胀阀与第一流量控制阀之间分支出以将制冷剂供应到蒸发器；以及控制单元，该控制单元用于根据室外空气温度或压缩机RPM来控制供应到除湿管线的制冷剂的量。
