To provide a vehicular air-conditioner capable of avoiding the degradation of suction density of a refrigerant of a compressor while improving a quick warming performance, and extending a life of the compressor.SOLUTION: A bypass path in which a refrigerant passing through a compressor 11 detours a heater core 12 and flows into a suction side 11b of the compressor 11 is equipped with a first path in which the refrigerant passing through the compressor 11 flows to an upstream side of an accumulator 15, and a second path in which the refrigerant passing through the compressor 11 flows to a downstream side of the accumulator 15.SELECTED DRAWING: Figure 1
【課題】速暖性の向上を図りつつ、圧縮機の冷媒の吸入密度の低下を回避し、併せて圧縮機の寿命を延ばすことができる車両用空調装置を提供する。【解決手段】圧縮機11を通過した冷媒がヒータコア12を迂回して圧縮機11の吸入側11bに流入するバイパス経路は、圧縮機11を通過した冷媒がアキュムレータ15の上流側に流れる第1経路と、圧縮機11を通過した冷媒がアキュムレータ15の下流側に流れる第2経路と、を備える。【選択図】図1
