Car air conditioning expands the feature of system of a powerful person is: Want a driver only one actuate air conditioning, electromagnetism clutch always is clench the teeth, never disconnect, compressor is in moving condition from beginning to end, rely on inspiratory throttle or rely on absolutely pressure valve to control evaporator temperature in 0 ℃ to control. And the feature of aperture canal system is: Electromagnetism clutch from time to time is united in wedlock, from time to time disconnects, compressor basis car is indoor, outside temperature from time to time moves, from time to time stops to move, because this also calls circular clutch the system.
