Abstract: A vehicular heat management system includes: a refrigerant circuit; a first heat medium circuit in which a heat medium circulates and exchanges heat with a low-pressure side refrigerant of the refrigerant circuit; a second heat medium circuit in which a heat medium circulates and exchanges heat with a high-pressure side refrigerant of the refrigerant circuit; and a switching device configured to switch a mode between a communicating mode in which the first heat medium circuit and the second heat medium circuit are coupled and a non-communicating mode in which the first heat medium circuit and the second heat medium circuit are not coupled on the basis of a temperature of the heat medium in the first heat medium circuit.

Abstract: A vehicular heat management system has a compressor, a heat-medium heating heat exchanger, and a flow adjustment part. The compressor draws and discharges a refrigerant. The heat-medium heating heat exchanger causes a heat exchange between the refrigerant discharged from the compressor and a heat medium other than air and heats the heat medium. The flow adjustment part causes a flow of a cooling fluid cooling the refrigerant when the compressor is stopped. The vehicular heat management system further has a refrigeration cycle unit and a refrigerant-flow-path forming member. The refrigeration cycle unit includes devices configuring a refrigeration cycle. The refrigerant-flow-path forming member (i) is disposed in a low-temperature area having an air temperature that is lower than an air temperature in an area in which the refrigeration cycle unit is disposed, and (ii) passes a refrigerant in the refrigeration cycle flows.

Abstract: An air conditioner for a vehicle includes a refrigeration cycle, a heating unit and a control unit. The refrigeration cycle includes an air-conditioning evaporator, a chilling evaporator, an air-conditioning side flow path, a detour flow path and an air-conditioning flow rate adjustment unit. The control unit includes a determination unit that determines whether a condensation condition is satisfied when a refrigerant is flowing through the chilling evaporator via the detour flow path in a state where an inflow of a refrigerant into the air-conditioning evaporator is prohibited. When the determination unit determines that the condensation condition is satisfied, the control unit controls the air-conditioning flow rate adjustment unit to allow an inflow of a refrigerant into the air-conditioning evaporator as a condensation suppression operation for suppressing condensation of a refrigerant in the air-conditioning evaporator.

Abstract: A vehicular air conditioner includes a refrigeration cycle system, a high-temperature heat medium circuit, and a low-temperature heat medium circuit. The high-temperature heat medium circuit includes an air-heat medium heat exchanger, a heater core, a branching portion, a common passage, a flow rate adjuster, and an auxiliary heat source. The air-heat medium heat exchanger exchanges heat between the heat medium and an outside air. The heater core is arranged parallel to the air-heat medium heat exchanger and causes the heat medium to transfer heat to a ventilation air. The branching portion divides a flow of the heat medium into a flow toward the air-heat medium heat exchanger and a flow toward the heater core. The auxiliary heat source is arranged in the common passage at a position upstream of the branching portion.

Abstract: A vehicle air-conditioner has a casing, a first heat exchanger, and a second heat exchanger. The casing forms an air passage through which air flows toward inside of a vehicle cabin. The first heat exchanger is housed in the casing and performs a sensible heat exchange between the air flowing in the air passage and a heating medium. The second heat exchanger is housed in the casing and performs a sensible heat exchange between the heating medium and air that has exchanged sensible heat in the first heat exchanger. The first heat exchanger and the second heat exchanger respectively have a plurality of tubes through which the heating medium flows. A longitudinal direction of the plurality of tubes of the first heat exchanger and a longitudinal direction of the plurality of tubes of the second heat exchanger are the same direction as each other.

Abstract: A refrigeration cycle device for a vehicle has a compressor, a first pump, a high-pressure side heat exchanger, a heating medium-outside air heat exchanger, and a controller. The compressor draws and discharges a refrigerant. The first pump draws and discharges a first heating medium. The high-pressure side heat exchanger heats the first heating medium by exchanging heat between a high-pressure refrigerant discharged from the compressor and the first heating medium. The heating medium-outside air heat exchanger exchanges heat between the first heating medium and outside air. The controller controls operation of the compressor and the first pump. The controller activates the first pump when an activation request of the compressor is made. The controller activates the compressor, after activating the first pump, when it is determined or estimated that a temperature of the first heating medium is lower than or equal to a first predetermined value.
