PURPOSE: An air conditioning system for a vehicle is provided to improve heating efficiency of vehicle interior and to reduce electric power supplied to a compressor. CONSTITUTION: An air conditioning system(100) for a vehicle comprises a refrigerant circulating line(R1) for a cooling mode, a coolant circulating line(W1) for the cooling mode, a refrigerant circulating line(R2) for a heating mode, and a coolant circulating line(W2) for the heating mode. A second outdoor heat exchanger(128) of the refrigerant circulating line for the heating mode transfers heat of coolant of the coolant circulating line of the heating mode. The coolant circulating line for the heating mode comprises an electronic unit(170), a pump(172), a three way valve(174), and the second outdoor heat exchanger. |
