Abstract: A vehicular heat management device includes a first heat source, a second heat source, a first heat generator, a second heat generator, a heat generator pathway, a first heat source pathway, a second heat source pathway, and a switching portion. The first heat source and the second heat source heat a heat medium. The first heat generator generates heat according to operation. The second heat generator generates heat according to operation. The first heat generator and the second heat generator are provided in the heat generator pathway. The first heat generator is provided in the first heat generator pathway. The second heat generator is provided in the second heat generator pathway. The switching portion switches between a condition where the heat generator pathway is in flowing communication with the first heat generator pathway and a condition where the heat generator pathway is in flowing communication with the second heat generator pathway.

Abstract: A heat pump system includes a heat pump cycle, a heating unit, a low-temperature side heat medium circuit, and a control unit. The heat pump cycle includes a compressor, a condenser, and an evaporator. The heating unit heats ventilation air with heat released form refrigerant in the condenser. The low-temperature side heat medium circuit circulates a low-temperature side heat medium such that the refrigerant in the evaporator absorbs heat of the low-temperature side heat medium, and includes a heat source device and a heat amount adjustment unit. The control unit causes an amount of heat transfer in the heating unit for heating the ventilation air to approach a predetermined target value via adjustment in temperature of the low-temperature side heat medium by controlling a rotation speed of the compressor and an operation of at least one of the heat source device and the heat amount adjustment unit.

Abstract: A vehicular heat management device includes a first heat source, a second heat source, a heater core, a first heat medium pathway, a second heat medium pathway, a heater core pathway, a switching portion, and a control unit. The first heat source is provided in the first heat medium pathway, and the second heat source is provided in the second heat medium pathway. The heater core is provided in the heater core pathway. The switching portion switches between flowing connection and flowing disconnection. The control unit performs at least one of a switching control and a second heat source control when a temperature of the heat medium of the heater core pathway is at or above a predetermined temperature. In the switching control, the switching portion connects the second heat medium pathway to the heater core pathway. In the second heat source control, the second heat source generates heat.
