The working principle of Rotary vane air conditioner compressor: By a rotor, three to four leaves, and the precise size of the rotor shell composition. When the shaft of air conditioner compressor rotates, the rotor blades and shell will form a small cavity. Air conditioner refrigerant reach to the suction holes when pumped into the small chamber, the small cavity size becomes small. After fully compressed, air conditioner refrigerant is arrival. Rotors and blades are sealed with oil under the centrifugal force. The tank and pumps are in the exhaust side, high pressure pumps push the oil through the end to the wheel, played in the rotor housing at the sealing effect. 

2, the control of air conditioner compressors:

The control of air conditioner compressors is carried out by the electromagnetic clutch.

As shown, the pulley of air conditioner compressor is supported by a bearing in the housing front. When no power in the electromagnetic coil, there is a certain gap between the pulley and pressure plate to separate, and then do not turn the input shaft, the air conditioner compressor does not work.

When the electromagnetic coil is energized, the magnetic field will appear, so that the pressure plate adsorbed on the pulley; the pulley driven by the pressure plate input shaft rotation, the air conditioner compressor will work.
