Beschreibung
Zusammenfassung:	To provide a vehicular air conditioner that can suppress deterioration of COP and occurrence of abnormal sound.SOLUTION: When an operation state of an air conditioner 1 is in a MAX-COOL state, an upper limit value of output of a compressor 41 provided in a coolant circulation circuit 4 is restricted, when output required to an electric fan 6 determined in accordance with a temperature of cooling water circulating in a cooling water circulation circuit 5 is larger than output required to the electric fan 6 determined in accordance with pressure of a coolant circulating in the coolant circulation circuit 4. This can suppress deterioration of COP and occurrence of abnormal sound.SELECTED DRAWING: Figure 1 【課題】ＣＯＰの悪化や異音の発生を抑制することができる車両用空調装置を提供する。【解決手段】空調装置１の運転状態がＭＡＸＣＯＯＬ状態となっている際、冷却水循環回路５を循環する冷却水の温度に応じて決定された電動ファン６に対する要求出力が、冷媒循環回路４を循環する冷媒の圧力に応じて決定された電動ファン６に対する要求出力よりも大きい場合には、冷媒循環回路４に備えられた圧縮機４１の出力の上限値を制限する。これにより、ＣＯＰの悪化や異音の発生を抑制することができる。【選択図】図１
