PROBLEM TO BE SOLVED: To suppress a decline in a heater core blowout air temperature when cooperating another heating medium circuit with a heating medium circuit having the heater core.SOLUTION: A vehicular air conditioner includes: a switching section 30 for switching between an independence mode in which a first heating medium circuit 31 and a second heating medium circuit 11 are independent of each other to circulate a heating medium and a cooperation mode in which the first heating medium circuit 31 and the second heating medium circuit 11 cooperate with each other to circulate the heating medium; and a control section 40 for controlling an operation of a first heating medium heater 1 so as to heat the heating medium circulating in the first heating medium circuit 31 when a temperature difference obtained by subtracting a temperature of the heating medium in the first heating medium circuit 31 from a temperature of the heating medium in the second heating medium circuit 11 exceeds a prescribed temperature difference α in the independence mode and controlling an operation of the switching section 30 so as to switch to the cooperation mode when the temperature difference reaches the prescribed temperature difference α or lower.SELECTED DRAWING: Figure 1

    【課題】ヒータコアを有する熱媒体回路に他の熱媒体回路を連携させるときにヒータコア吹出空気温度が低下することを抑制する。【解決手段】第1熱媒体回路31と第2熱媒体回路11とが互いに独立に熱媒体を循環させる独立モードと、第1熱媒体回路31と第2熱媒体回路11とが互いに連携して熱媒体を循環させる連携モードとを切り替える切替部30と、独立モードにおいて第2熱媒体回路11の熱媒体の温度から第1熱媒体回路31の熱媒体の温度を減じた温度差が所定温度差αを上回っている場合、第1熱媒体回路31を循環する熱媒体を加熱するように第1熱媒体加熱器1の作動を制御し、温度差が所定温度差α以下になった後に連携モードに切り替えるように切替部30の作動を制御する制御部40とを備える。【選択図】図1
