12V Auto A/C Compressor Manufacture Factory For Subaru Impreza / Subaru Stella / Subaru Impreza XV

The automobile air conditioning compressor is the heart of the automobile air conditioning system, which plays the role of compressing and conveying refrigerant steam. AC compressors are divided into two kinds: non-variable and variable displacement. Air conditioning compressor can be divided into fixed displacement compressor and variable displacement compressor according to the different working principle.

The displacement of the fixed displacement compressor is proportional to the increase of the engine speed, it can't automatically change the power output according to the demand of refrigeration and the impact on the engine fuel consumption is relatively large. It is controlled by collecting the temperature signal of the outlet of the evaporator. When the temperature reaches the set temperature, the electromagnetic clutch of the compressor is released and the compressor stops working. When the temperature rises, the electromagnetic clutch is combined and the compressor begins to work. The constant displacement compressor is also controlled by the pressure of the air conditioning system. When the pressure in the pipeline is too high, the compressor stops working.

The variable displacement compressor can automatically adjust the power output according to the set temperature. The air conditioning control system doesn't collect the temperature signal of the evaporator air outlet, but automatically adjusts the air outlet temperature by controlling the compression ratio of the compressor according to the change signal of the pressure in the air conditioning pipeline. During the whole process of refrigeration, the compressor is always working, and the adjustment of refrigeration intensity is completely dependent on the pressure regulating valve installed inside the compressor to control. When the pressure at the high pressure end of the air conditioning pipeline is too high, the pressure regulating valve shortens the piston stroke in the compressor to reduce the compression ratio, which will reduce the cooling strength. When the pressure at the high pressure end drops to a certain extent and the pressure at the low pressure end rises to a certain extent, the pressure regulating valve increases the piston stroke to improve the cooling strength.
