    Abstract: The present invention relates to a heat pump system for a vehicle. The heat pump system includes a refrigerant-coolant heat exchanger for exchanging heat between refrigerant circulating through a refrigerant circulation line and coolant circulating through electronic units of the vehicle. The heat pump system can operate the heat pump mode even though outdoor air temperature is zero or lower or frosting is formed on the external heat exchanger because waste heat of the electronic units is retrieved through the refrigerant-coolant heat exchanger, thereby further enhancing heating performance and efficiency.

    Abstract: The present invention relates to a vehicular heat pump system and, more specifically, to a vehicular heat pump system having a chiller for heat exchanging cooling water circulating through vehicle electrical equipment (200), a refrigerant discharged from an outdoor heat exchanger so as to flow through a first bypass line (R1), and a refrigerant discharged from an indoor heat exchanger, thereby: in the air conditioner mode, increasing sub-cool while the refrigerant discharged from the indoor heat exchanger is first cooled at the chiller and then is second cooled at the outdoor heat exchanger such that the flow rate of refrigerants increases and cooling performance is improved; in the heat pump mode, allowing the refrigerant discharged from the indoor heat exchanger to ensure sub-cool in the chiller so as to increase the flow rate of refrigerants, and allowing the refrigerant discharged from the outdoor heat exchanger to receive an additional heating source from the chiller so as to improve heating performance; and, even in the defrost mode carried out because of frost on the outdoor heat exchanger, ensuring an additional heating source in the chiller so as to minimize a change in indoor discharge temperature because of a lack of heating sources.

    Abstract: The present invention relates to a heat pump system for a vehicle which includes a refrigerant-coolant heat exchanger mounted on a refrigerant circulation line of an inlet side of an external heat exchanger to exchange heat between coolant induced into the external heat exchanger and coolant circulating through electronic units of the vehicle, thereby enhancing cooling performance and reducing power consumption without an increase in size of the external heat exchanger by increasing a condensation amount because refrigerant radiates heat while passing through the refrigerant-coolant heat exchanger and the external heat exchanger in an air-conditioning mode and enhancing heating performance and reducing power consumption by increasing an evaporation amount because refrigerant absorbs heat while passing through the refrigerant-coolant heat exchanger, the external heat exchanger and a chiller in a heat pump mode, and increasing temperature of the refrigerant induced into the external heat exchanger to delay frosting of the external heat exchanger.

    Abstract translation: 本发明涉及一种用于车辆的热泵系统，其包括：制冷剂 - 冷却剂热交换器，其安装在外部热交换器的入口侧的制冷剂循环管线上，以便在引入外部热交换器的冷却剂和循环通过的冷却剂之间进行热交换 电子单元，由于制冷剂在空气中通过制冷剂 - 冷却剂热交换器和外部热交换器而散热，因此通过增加冷凝量而不增加外部热交换器的尺寸而提高冷却性能并降低功率消耗 调节模式，并且通过增加蒸发量来提高加热性能并降低功率消耗，因为制冷剂在热泵模式中通过制冷剂 - 冷却剂热交换器，外部热交换器和冷却器时吸收热量，并且致冷剂的温度升高 进入外部热 交换器延迟外部热交换器的结霜。
