Document Type and Number:
Japanese Patent JP4096548
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce power consumption and size of an electric motor in an air conditioner driving a compressor by changing between an engine for traveling and the electric motor. SOLUTION: A pressure reducing device 120 is composed of a capillary tube. By this, since a front and a rear of the pressure reducing device 120 are in a communicated state, and when the engine 200 stops, refrigerant of a high pressure side moves to a lower pressure side via the pressure reducing device 120, a high pressure side refrigerant pressure is reduced, and refrigerant pressures of the front and rear of the pressure reducing device 120 become equal, driving torque in driving the compressor 100 by the motor 210 can be reduced. Consequently, the size of the motor 210 can be reduced while reducing the power consumption of the motor 210.
