HEAT MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/070421
Kind Code:
A1
Abstract:
[Problem] To provide a heat management system for switching between heat management modes by switching flow paths in a heating medium circuit, wherein temperature management of a temperature-regulated target can be stably continued during mode switching, and wherein the heat management system can be operated stably while appropriate mode switching is being performed. [Solution] This heat management system is provided with a refrigeration circuit for executing a refrigeration cycle, and a heating medium circuit for circulating a heating medium to exchange heat with refrigerant in the refrigerant circuit, the system performing heat management of a temperature-regulated target by using a high-temperature heating medium that was heated by heat radiation from the refrigerant circuit and a low-temperature heating medium that was cooled by heat absorption in the refrigerant circuit. The heating medium circuit is provided with a flow path switching means for switching flow paths in order to execute a plurality of heat management modes. The switching of flow paths by the flow path switching means involves switching to a prescribed heat management mode via a transition mode that prioritizes temperature management of the temperature-regulated target.
