In a cooling cycle having an evaporator 7 that exchanges heat with air blown into the vehicle interior and cools the air, the refrigerant conduit 8b between the condenser 4 and the expansion valve 6 has both ends 10a, 10b is the refrigerant conduit 8
A bypass passage 10 communicating with the interior of b is connected, an on-off valve 12 is attached to this bypass passage 10, and the refrigerant pressure in the high pressure side path from the compressor 3 to the expansion valve 6 is detected, and this refrigerant pressure is set to a predetermined pressure. A cooling device for an automobile, characterized in that the on-off valve 12 is provided with a pressure sensor 13 that opens the on-off valve 12 in the above situations.
