IN-VEHICLE DEVICE TEMPERATURE ADJUSTING DEVICE AND VEHICLE AIR CONDITIONING DEVICE PROVIDED WITH SAME

It is an object to improve the reliability of a temperature adjusting device which cools an in-vehicle device such as a battery by using a refrigerant. A device temperature adjusting device that is an in-vehicle device temperature adjusting device adjusts the temperature of a battery mounted on a vehicle and includes a refrigerant circuit R having a compressor which compresses a refrigerant, an outdoor heat exchanger for letting the refrigerant radiate heat, and a refrigerant-heat medium heat exchanger for cooling the battery by letting the refrigerant absorb heat, and a control device . The control device stops the compressor on the basis of the fact that the refrigerant circuit R is blocked.
