Title:
VEHICLE HEAT MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/250020
Kind Code:
A1
Abstract:
The present invention suppresses heat loss while making it possible to perform temperature control by heat media in different temperature zones in a vehicle heat management system. Provided is a vehicle heat management system including a refrigerant circuit and a heat medium circuit in which a heat medium that has exchanged heat with the refrigerant in a refrigerant-heat medium heat exchanger provided to the refrigerant circuit circulates, wherein the refrigerant circuit selects two or more of at least three heat exchangers and designates some of the selected heat exchangers as condensers and the others as evaporators, the refrigerant-heat medium heat exchanger designates one of the selected heat exchangers as a first refrigerant-heat medium heat exchanger and one other selected heat exchanger as a second second refrigerant-heat medium heat exchanger, and the heat medium circuit comprises a switching means capable of switching between a circuit state in which the heat medium subjected to heat exchange in the second refrigerant-heat medium heat exchanger flows to the first refrigerant-heat medium heat exchanger and a circuit state for obtaining a circuit in which a flow path through which the heat medium subjected to heat exchange by the first refrigerant-heat medium heat exchanger flows and the flow path through which the heat medium subjected to heat exchange by the second refrigerant-heat medium heat exchanger flows are independent from each other.
