PURPOSE:To permit the speedy cooling for an electric motor and the speedy cooing and heating in a car interior by heating an accumulator by the outside air temperature in the cooling mode, while by the battery operation heat in the warming mode, and raising the internal pressure without sharply raising the starting torque and the compression torque. CONSTITUTION:In the cooling mode, the coolant inside an accumulator 11 for the outside air temperature of e.g. 30 deg.C or above generates the vapor pressure corresponding to this temperature, and a solenoid valve 10d is closed, and a solenoid valve, 10c is opened to allow the sucked coolant to flow into a coolant flow passage 15a, and the suction pressure is adjusted by a suction pressure adjusting valve 13a. In the warming mode, solenoid valves 10e and 10f are closed and a solenoid valve 10g is opened, and the accumulator 11 and a battery 12 are connected by a heating pipe 16. When a compressor 1 is started, the internal pressure of the accumulator 11 lowers, and the coolant liquid is sucked toward the battery 12, and the coolant which is heated and vaporized by the operation heat of the battery 12 is returned, and the internal pressure rises, and the coolant is sucked into the compressor 1. |
