    Abstract: A heat pump system including a compressor mounted on a refrigerant circulation line for compressing and discharging refrigerant. An internal heat exchanger is mounted inside an air-conditioning case. An evaporator is mounted inside the air-conditioning case. An external heat exchanger is mounted outside the air-conditioning case. A first expansion means is mounted on the refrigerant circulation line between the internal heat exchanger and the external heat exchanger to selectively expand refrigerant discharged from the internal heat exchanger. A second expansion means is mounted on the refrigerant circulation line of an inlet side of the evaporator to expand the refrigerant supplied to the evaporator. A coolant circulation line is configured to circulate coolant toward electronic units of the vehicle. A refrigerant-coolant heat exchanger is configured to exchange heat between the refrigerant flowing the refrigerant circulation line and the coolant circulating through the coolant circulation line.

    Abstract: A vehicle air conditioner is disclosed. The present invention provides the vehicle air conditioner, which: can directly control the amount of air passing through an evaporator and a heater core since a blower is disposed between the evaporator and the heater core; has front and rear seat discharge units respectively having heater cores, thereby having a simple form, minimizing energy consumption, and independently enabling four or more zones, including front and rear seats, the left and right of the front seats, and the left and right of the rear seats, to be air-conditioned; and can discharge an offensive smell to the outside during initial driving of a vehicle since the air outside a vehicle, flowing in from an air inlet, and indoor air flowing in from an inside air suction port, disposed at the center of the vehicle, are discharged to the outside of the vehicle by means of a second blower, and not by a front seat blower, for discharging the air to the rear seats.

    Abstract: Vehicular heat management system includes a refrigerant circulation line including a compressor, a high pressure side indoor heat exchanger, a heat pump mode expansion valve, an outdoor heat exchanger, an air conditioning mode expansion valve, low pressure side indoor heat exchanger and a refrigerant-cooling water heat exchanger; an air conditioning mode branch line branched from the refrigerant circulation line and configured to, in an air conditioning mode, form a cooling loop by circulating a refrigerant through the compressor, the high pressure side indoor heat exchanger, the outdoor heat exchanger, the air conditioning mode expansion valve and low pressure side indoor heat exchanger. Heat pump mode branch line branched from the refrigerant circulation line is configured, in heat pump mode to form a heating loop by circulating the refrigerant through the compressor, the high pressure side indoor heat exchanger, the heat pump mode expansion valve and the refrigerant-cooling water heat exchanger.

    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.
