The scroll compressor for vehicle air conditioner is a compressor with compressible volume composed of a fixed involute scroll and an involute scroll which is in eccentric rotary translation. During the working process of air suction, compression and exhaust, the fixed disc is fixed on the frame, and the movable disc is driven by the eccentric shaft and restricted by the anti-rotation mechanism to rotate around the center of the base circle of the fixed disc in a plane with a small radius. The air is sucked into the periphery of the fixed disc through the air filter element, and along with the rotation of the eccentric shaft, the air is gradually compressed in a plurality of crescent compression cavities formed by fitting the movable fixed disc and then is continuously discharged from the axial hole of the central part of the fixed disc. In cold winter or in perennial low-temperature areas such as the north, the traditional vehicle air conditioner needs to be preheated at a low rotating speed for three to five minutes in the starting process. This is because under the low temperature state, there may be liquid refrigerant in the compression chamber, under the high-speed rotation of scroll compressor, because the incompressible of refrigerant, the pressure in the compression chamber can be very big, this makes the scroll compressor be in very abominable operating condition, seriously influences the life of compressor spare part.
