Abstract: The present invention relates to an air conditioning system for a vehicle in which an air-conditioning module having an air-conditioning case and a blower unit is disposed at a side of an engine room relative to a dash panel, and a distribution duct having a defrost vent, a face vent, and a floor vent is disposed in the interior of a vehicle relative to the dash panel so as to distribute cold air and hot air discharged from the air-conditioning case into the interior of the vehicle, wherein the floor vent is placed on one side of an area, in which a relatively large amount of hot air flows, in a mixing chamber of the distribution duct where cold air and hot air are mixed, i.e. a side adjacent to the dash panel.

Abstract: The present invention relates to a vehicle air-conditioning system and, more particularly, to a vehicle air-conditioning system in which an air-conditioning module consisting of an air-conditioning case and a blowing apparatus is disposed at a side of an engine room with respect to a dash panel, and a distribution duct for distributing cold and hot air discharged from the air-conditioning case into the inside of a vehicle is disposed on the indoor side of the vehicle with respect to the dash panel. The vehicle air-conditioning system may prevent a reverse flow of outdoor air into a cold air discharge port and a hot air discharge port due to the wind pressure when driving by forming a shielding means at the sides of the cold air discharge port and the hot air discharge port, which discharge the cold and hot air of the air-conditioning case to the outside, thereby improving the cooling and heating performance by smoothly discharging heat through the cold air discharge port and the hot air discharge port.

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.
