PROBLEM TO BE SOLVED: To adjust a difference between temperatures of air blown out from a face opening portion and a foot opening portion and reduce temperature unevenness of the air blown out from the face opening portion and the foot opening portion.SOLUTION: An vehicular air conditioning unit includes: fans 25a, 25b that are disposed on the air flow downstream side of a heater core 18 to suck air from an upper air passage 120a and send the air to a face opening portion 20 and to suck air from a lower air passage 120b and send the air to a foot opening portion 21; and an adjustment section 30 that is disposed between the heater core 18 and the fans 25a, 25b, has a communication portion 310 for communicating the upper air passage 120a and the lower air passage 120b with each other and adjusts a temperature difference between the air flowing in the upper air passage 120a and the air flowing in the lower air passage 120b by introducing air into the communication portion 310.SELECTED DRAWING: Figure 1
【課題】フェイス開口部およびフット開口部から吹き出される空気の温度差を調整できるようにするとともに、フェイス開口部およびフット開口部から吹き出される空気の温度ムラを低減する。【解決手段】ヒータコア18より空気流れ下流側に配置されて、上側空気通路120aから空気を吸い込んでフェイス開口部20へ送風するとともに下側空気通路120bから空気を吸い込んでフット開口部21へ送風するファン25a、25bと、ヒータコア18とファン25a、25bとの間に配置され、上側空気通路120aと下側空気通路120bの間を連通する連通部310を有し、該連通部310に空気を導入して上側空気通路120aを流れる空気と下側空気通路120bを流れる空気の温度差を調整する調整部30を備える。【選択図】図1
