To provide a vehicular heating device capable of suppressing the reduction in heating performance in accordance with the increase in flow resistance while utilizing exhaust heat of a vehicle engine when operating the vehicle engine.SOLUTION: A vehicular air-conditioner 1 includes a refrigeration cycle device 10, an indoor air conditioning unit 30, a heating-side heat medium circuit 40, and a control device. The vehicular air-conditioner 1 radiates heat of cooling water circulating in the heating-side heat medium circuit 40 by a heater core 43 to heat a cabin. The heating-side heat medium circuit 40 includes an engine EG, a radiator 12 of the refrigeration cycle device 10, a heating-side water pump 41, a water heating heater 42, and a flow regulating valve 47. In a case of an HV traveling mode in a heating mode, the control device controls the operation of the heating-side water pump 41 and the flow regulating valve 47 such that a cooling water flow rate on the side of a first connection flow passage passing through the engine EG is larger than the cooling water flow rate on the side of a second connection flow passage passing through the radiator 12 and the water heating heater 42.SELECTED DRAWING: Figure 1

    【課題】車両エンジン作動時において、車両エンジンの排熱を利用しつつ、通水抵抗の増大に伴う暖房性能の低下を抑制可能な車両用暖房装置を提供する。【解決手段】車両用空調装置1は、冷凍サイクル装置10と、室内空調ユニット30と、加熱側熱媒体回路40と、制御装置とを有している。車両用空調装置1は、加熱側熱媒体回路40を循環する冷却水の熱をヒータコア43で放熱させて車室内の暖房を行う。加熱側熱媒体回路40は、エンジンEG、冷凍サイクル装置10の放熱器12、加熱側水ポンプ41、水加熱ヒータ42、流量調整弁47を有している。暖房モード時にHV走行モードである場合、制御装置は、エンジンEGを経由する第1接続流路側の冷却水流量が、放熱器12や水加熱ヒータ42を経由する第2接続流路側の冷却水流量より大きくなるように、加熱側水ポンプ41や流量調整弁47の作動を制御する。【選択図】図1
