Abstract: The present invention relates to an air conditioning system for a vehicle and a method for controlling the same and, more specifically, to an air conditioning system for a vehicle and a method for controlling the same in which an opening/closing valve and an expansion valve are installed on a branch line connecting a first air conditioning unit and a second air conditioning unit, the opening/closing valve is always open so as to always supply a refrigerant to the second air conditioning unit during a cooling mode, and the opening/closing valve is always closed so as to always block the refrigerant supply to the second air conditioning unit during a heating mode, such that the refrigerant flows into the branch line of the second air conditioning unit even during a single cooling mode, thereby solving the problem wherein the pressure of a compressor increases, oil is forcibly circulated through a notch of the expansion valve, thereby solving the problem wherein the oil circulation rate decreases, and the refrigerant supply to the second air conditioning unit is blocked during a dual heating mode, thereby solving the problem wherein the heating performance of an electric heating type heater decreases when the second air conditioning unit is operated.

Abstract: A vehicular heat management system is provided with a heat pump type refrigerant circulation line that cools and heats specific air conditioning regions by generating a hot air or a cold air depending on a flow direction of a refrigerant. The system includes a compressor configured to suck, compress and discharge the refrigerant, a high-pressure side heat exchanger configured to dissipate heat of the refrigerant discharged from the compressor, an outdoor heat exchanger configured to allow the refrigerant to exchange heat with an air outside the vehicle, an expansion valve configured to depressurize the refrigerant flowing out of the high-pressure side heat exchanger or the outdoor heat exchanger, and one or more low-pressure side heat exchangers configured to evaporate the depressurized refrigerant. The outdoor heat exchanger and the low-pressure side heat exchangers are connected in series or in parallel depending on an air conditioning mode.
