To provide an air conditioner which can discharge foreign objects falling from a heat exchanger to the outside of an air conditioning unit.SOLUTION: An air conditioning unit 3 includes: an air conditioning case 30; a blower 31 which flows air down to an interior of the air conditioning case 30; an evaporator 32 which conducts heat exchange between the air flowed down by the blower 31 and an internal fluid; and a discharge port 5 forming a discharge passage allowing communication between an interior and an exterior of the air conditioning case 30. The discharge port 5 has an opening end part 50 which at least partially opens at the interior of the air conditioning case 30 at the upstream of airflow relative to an air passing inlet surface 320 in a heat exchange core part of the evaporator 32. The air conditioning unit 3 can discharge foreign objects falling from the evaporator 32 to the outside of the air conditioning unit 3 through the discharge port 5.SELECTED DRAWING: Figure 12
【課題】熱交換器から脱落した異物を空調ユニットの外部に排出可能な空調装置を提供する。【解決手段】空調ユニット3は、空調ケース30と、空気を空調ケース30内に流下させる送風機31と、送風機31によって流下する空気と内部流体とが熱交換する蒸発器32と、空調ケース30の内外を連通する排出通路を形成する排出ポート5とを備える。排出ポート5は、蒸発器32の熱交換コア部における空気の通過入口面320よりも空気流れの上流において、空調ケース30の内部に少なくとも一部が開口している開口端部50を有する。空調ユニット3は蒸発器32から脱落した異物を排出ポート5を通じて空調ユニット3の外部に排出することができる。【選択図】図12
