To suppress harmful effect of electromagnetic noise occurring in a motor of a blower without increasing the physical constitution, the weight, and the number of components of an air conditioning unit mounted on a vehicle.SOLUTION: An air conditioning unit includes: an air-conditioning case; a blower which sends air in the air-conditioning case to a passenger compartment 4 of a vehicle 1; a blower motor which drives the blower; and a heater core 18 in the air-conditioning case. The heater core 18 includes a substance which is disposed between a circuit part 204, a noise source which generates electromagnetic noise in the blower motor, and a protection area G, at least a part of the passenger compartment 4, to shield the electromagnetic noise.SELECTED DRAWING: Figure 1
【課題】車両に搭載される空調ユニットの体格、重量、部品点数増加させることなく、送風機のモータで発生する電磁ノイズの悪影響を抑える。【解決手段】空調ユニットは、空調ケースと、空調ケース内の空気を車両1の車室4内に送る送風機と、送風機を駆動する送風機モータと、空調ケース内のヒータコア18と、を備える。ヒータコア18は、送風機モータにおいて電磁ノイズを発生するノイズ源である回路部204と車室4内の少なくとも一部である保護領域Gとの間に配置されて電磁ノイズを遮蔽する物質を含む。【選択図】図1
