To improve comfort for an occupant by efficient heating operation even when an outside air temperature is low.SOLUTION: A vehicle air conditioning system 10 includes: an air flow passage part 11 in which air supplied to a cabin space 3 flows; a blower 20 which is arranged in the air flow passage part 11 and sends the air to the cabin space 3: a heater core 40 which is arranged in the air flow passage part 11 and heats the air by a liquid medium used in a vehicle 1 as a heat source; a blowout port 14 which blows out the air through the heater core 40 to the cabin space 3; an air circulation path 50 having an air intake port 51 which is arranged at a downstream side of a flow direction of the air than the heater core 40 and takes a part of the air through the heater core 40 from the air flow passage part 11, a heater upstream side discharge port 52 and an evaporator upstream side discharge port 53 which are arranged at an upstream side of a flow direction of the air than the heater core 40 and discharge a part of the air taken from the air intake port 51 to the air flow passage part 11.SELECTED DRAWING: Figure 1 【課題】外気温が低い状態であっても、効率良く暖房運転を行って乗員の快適性を高めることを目的とする。【解決手段】車両用空気調和システム１０は、車内空間３に供給される空気が流れる空気流路部１１と、空気流路部１１内に設けられ、車内空間３に空気を送るブロワ２０と、空気流路部１１内に設けられ、車両１で用いられる液媒を熱源として空気を加熱するヒータコア４０と、ヒータコア４０を経た空気を車内空間３に吹き出す吹出口１４と、ヒータコア４０よりも空気の流れ方向下流側に設けられ、ヒータコア４０を経た空気の一部を空気流路部１１から取り込む空気取込口５１、及びヒータコア４０よりも空気の流れ方向上流側に設けられ、空気取込口５１から取り込んだ空気の一部を空気流路部１１に吐出するヒータ上流側吐出口５２、エバポレータ上流側吐出口５３を有した空気循環路５０と、を備える。【選択図】図１
