A heat medium temperature adjustment system includes a heat medium circuit configured to circulate heat medium having a temperature controlled by a heat exchange with a heat source. The heat medium circuit includes a pump configured to pump the heat medium, and a plurality of heat exchangers for temperature-adjustment subjects configured to perform heat exchanges with temperature-adjustment subjects. The heat medium circuit is configured to form a series flow path to connect the pump to the plurality of heat exchangers for temperature-adjustment subjects when a system malfunction occurs.

Heat medium temperature adjustment system

There are included a first heat exchanger () for causing heat to be exchanged between refrigerant and air in an interior of a vehicle (), a heating circuit () for causing the refrigerant with a temperature higher than that of the air in the interior of the vehicle to circulate through the first heat exchanger, a secondary battery () where charging and discharging of power are performed, a cooling water circuit () for causing cooling water that exchanges heat with the secondary battery to circulate, a second heat exchanger () for causing heat to be exchanged between the refrigerant and the cooling water, the second heat exchanger being provided in a manner including a portion of the heating circuit downstream of the first heat exchanger and a portion of the cooling water circuit, and a case () for covering the secondary battery, the cooling water circuit, and the second heat exchanger.

Vehicular heat exchange system and motor unit used in same

A vehicle air-conditioning device is provided which is capable of eliminating or suppressing vibration and noise generated due to the application of a counterpressure to an opening/closing valve. The vehicle air-conditioning device includes a refrigerant circuit R having a compressor, a radiatorto perform heat exchange between a refrigerant and air, an outdoor heat exchanger, a heat absorber, and a solenoid valve. The compressorand the solenoid valveare controlled to air-condition a vehicle interior. A decompression speed at a refrigerant inflow side of the solenoid valve when the compressoris stopped and the solenoid valveis closed is faster than that at a refrigerant outflow side thereof. When operation is stopped from a state in which the compressoris operating with the solenoid valvebeing in an opened state, the opened state of the solenoid valveis maintained even after the compressoris stopped.

Vehicle air-conditioning device

There is disclosed a vehicle air conditioner device which is capable of continuing air conditioning of a vehicle interior also in a case where a failure occurs in a solenoid valve to change a flow of a refrigerant in each operation mode. A vehicle air conditioner deviceincludes a solenoid valvefor cooling, a solenoid valvefor heating and a solenoid valvefor dehumidifying to switch respective operation modes of the vehicle air conditioner device. A controller changes and executes the respective operation modes of a heating mode, a dehumidifying mode, and a cooling mode. The controller has a predetermined air conditioning mode during failure, and failure detecting means for detecting failure of the solenoid valve. In a case where the failure detecting means detects that the solenoid valves fail in the respective operation modes, the controller selects the air conditioning mode during failure in which vehicle interior air conditioning by the operation mode is achievable, to continue the air conditioning of the vehicle interior.
