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: In a refrigeration cycle device, a heat supply unit is disposed in parallel with a heat utilization unit in a flow of a heat medium. A branching part branches the heat medium flowing out of a heat radiator into a flow flowing toward the heat utilization unit and a flow flowing toward the heat supply unit. A merging part is configured to cause the heat medium having passed through the heat utilization unit and the heat medium having passed through the heat supply unit to merge together and to flow toward the heat radiator. A switching unit switches an operation state between a first state in which the heat medium circulates between the heat radiator and the heat utilization unit, and a second state in which the heat medium circulates between the heat radiator, the heat utilization unit and the heat supply unit.

Abstract: A refrigeration cycle device includes a heat pump cycle, a high-temperature heat medium circuit, and a low-temperature heat medium circuit. The low-temperature heat medium circuit includes a plurality of heat absorption devices configured to have a heat absorption amount to be absorbed by the low-temperature heat medium flowing out of a low-temperature heat medium-refrigerant heat exchanger, and a heat absorption adjusting unit configured to change the heat absorption amount of the low-temperature heat medium in the respective heat absorption devices. In the refrigeration cycle device, a flow amount of the refrigerant flowing into the low-temperature heat medium-refrigerant heat exchanger is reduced when the heat absorption adjusting unit changes the heat absorption amount of the low-temperature heat medium in the respective heat absorption devices, and the flow amount of the refrigerant flowing into the low-temperature heat medium-refrigerant heat exchanger is increased when a recovery condition is satisfied.

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.

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.
