PROBLEM TO BE SOLVED: To suppress deterioration of cooling efficiency during operation start of a vehicular air conditioner.SOLUTION: An ECU 40 for a vehicular air conditioner 1 comprises: a suction chamber 10 having a blower 11 for selectively introducing ambient air from a cabin or outside of a vehicle; and a temperature adjustment chamber 30 for receiving introduction of the ambient air from the suction chamber 10. The temperature adjustment chamber 30 comprises: an evaporator 34 disposed on an upstream side of an air stream of the suction chamber 10; a heater core 35 disposed on a downstream side of the evaporator 34; a mixing door 36 for adjusting an air flow rate entering the heater core 35; a face side open circuit 31 capable of being opened and closed by an opening/closing door 31a; a foot side open circuit 32 capable of being opened and closed by an opening/closing door 32a; and a defroster side open circuit 33 capable of being opened and closed by an opening/closing door 33a. The ECU performs stop preliminary control so as to operate the mixing door 36 so that the flow rate entering the heater core 35 becomes maximum immediately after stop of cooling operation, then close the face side open circuit 31, and open at least one of the foot side open circuit 32 and defroster side open circuit 33.SELECTED DRAWING: Figure 1

    【課題】 車両用空調装置の運転開始時における冷房効率の低下を抑制する。【解決手段】 車内又は車外から外気を選択的に導入するブロワー11を有する吸気室10と、吸気室10から外気の導入を受ける温度調節室30とを備え、温度調節室30は、吸気室10による空気流の上流に位置するエバポレータ34と、エバポレータ34より下流に位置するヒータコア35と、ヒータコア35への空気の流量を調節する混合ドア36と、開閉ドア31aにより開閉自在なフェイス側開路31と、開閉ドア32aにより開閉自在なフット側開路32と開閉ドア33aにより開閉自在なデフロスタ側開路33とを有する車両用空調装置1のECU40であって、冷房運転の停止直後に、ヒータコア35への流量が最大になるよう混合ドア36を動作させるとともに、フェイス側開路31を閉止し、フット側開路32及びデフロスタ側開路33の少なくともいずれか一方を開放する停止予備制御を行う。【選択図】 図1
