Title:
HEAT MANAGEMENT DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/042988
Kind Code:
A1
Abstract:
The present invention addresses the problem of seamlessly transitioning operation modes to improve comfortableness even before and after the transition of operation modes. A heat management device for a vehicle according to the present invention is provided with: a refrigerant circuit that includes a compressor which compresses a refrigerant; a plurality of heat exchangers that heat or cool a plurality of temperature adjustment targets by using heat emission or heat absorption of the refrigerant circulating through the refrigerant circuit and that are provided for the respective temperature adjustment targets; and a control unit that controls the refrigerant circuit. The control unit has: a required heat exchange amount calculation unit that calculates, for each of the temperature adjustment targets, a required heat exchange amount which is required for heating or cooling the temperature adjustment target in the heat exchanger; and a rotation speed control unit that controls, when simultaneously heating and cooling the plurality of temperature adjustment targets, the compressor in accordance with a target rotation speed which is decided on the basis of the total amount of the required heat exchange amounts calculated for the temperature adjustment targets.
