Abstract
A vehicle heat management system includes a refrigerant circuit including a refrigerant-heat medium heat exchanger, and a heat medium circuit. Two or more of at least three heat exchangers are selected, and one of them functions as a condenser, and the other functions as an evaporator. The refrigerant-heat medium heat exchanger includes a first and a second refrigerant-heat medium heat exchanger. The heat medium circuit includes a switch device configured to be able to switch between a circuit state in which the heat medium having passed through the second refrigerant-heat medium heat exchanger flows to the first refrigerant-heat medium heat exchanger and a circuit state in which a flow path of the heat medium having passed through the first refrigerant-heat medium heat exchanger and a flow path of the heat medium having passed through the second refrigerant-heat medium heat exchanger form individual circuits, respectively.
