To improve comfort before and after transition of a driving mode by seamlessly transiting the driving mode.SOLUTION: A vehicular heat management device includes: a refrigerant circuit which includes a compressor for compressing a refrigerant; a plurality of heat exchangers which heat or cool each of a plurality of temperature control target objects by utilizing heat release or heat absorption of the refrigerant circulating in the refrigerant circuit and are provided for each temperature control target object; and a control section which controls the refrigerant circuit. The control section has a required heat exchange amount calculation section which calculates required heat exchange amount to be required to heat or cool the temperature control target objects in a heat exchanger for each temperature control target object, and a rotation number control section which controls the compressor in accordance with a target rotation number to be determined on the basis of a total value of the required heat exchange amount calculated for each temperature control target object when simultaneously heating or cooling the plurality of temperature control target objects.SELECTED DRAWING: Figure 3
【課題】運転モードをシームレスに遷移させ、運転モードの遷移前後においても快適性を向上させる。【解決手段】冷媒を圧縮する圧縮機を含む冷媒回路と、冷媒回路を循環する冷媒の放熱又は吸熱を利用して複数の温調対象をそれぞれ加熱又は冷却し、温調対象毎に設けられる複数の熱交換器と、冷媒回路を制御する制御部と、を備え、制御部は、熱交換器において温調対象を加熱又は冷却するために必要となる必要熱交換量を温調対象毎に算出する必要熱交換量算出部と、複数の温調対象に対して同時に加熱又は冷却を行う場合に、温調対象毎に算出された必要熱交換量の合計値に基づいて決定される目標回転数に従って圧縮機を制御する回転数制御部と、を有する車両用熱管理装置を提供する。【選択図】図3
