Vehicle air conditioner using variable control compressor

摘要

The vehicle air conditioner includes a compressor that compresses the refrigerant of an air conditioner by receiving rotational force from the engine. A clutch transmits or isolates the rotational force of the engine to a compressor shaft by using an operational fluid. A shearing force of the operational fluid varies according to the variation of the magnetic field. A controller varies the shearing force of the operational fluid by adjusting the magnetic field according to the cooling load.
