SHACMAN TRUCK AC COMPRESSOR DESCRIPTION:
The function of SHACMAN TRUCK AC COMPRESSOR is to compress and transport refrigerant steam.
According to different working principles, SHACMAN TRUCK AC COMPRESSOR can be divided into fixed displacement compressors and variable displacement compressors.
Constant displacement compressor
The exhaust volume of the constant displacement SHACMAN TRUCK AC COMPRESSOR is proportional to the engine's speed. It can not automatically change the power output according to the demand of the refrigeration, and it has a great influence on the fuel consumption of the engine. Its control generally passes the temperature signal of the air outlet by collecting the evaporator. When the temperature reaches the set temperature, the electromagnetic clutch of the compressor is loosened and the compressor stops working. When the temperature rises, the electromagnetic clutch is combined, and the compressor starts to work. The fixed 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.
Variable displacement air conditioner compressor
The variable displacement SHACMAN TRUCK AC COMPRESSOR can automatically adjust the power output according to the set temperature. The air conditioning control system does not collect the temperature signal of the evaporator outlet, but automatically adjusts the air outlet temperature according to the change signal of the pressure in the air conditioning pipeline to control the compressor's compression ratio. In the whole process of refrigeration, the compressor is always working, and the adjustment of refrigeration intensity depends entirely on the pressure regulating valve installed inside the compressor. When the pressure of the high pressure end of the air-conditioning pipe is too high, the pressure control valve shortens the piston stroke in the compressor to reduce the compression ratio, which will reduce the refrigeration intensity. When the pressure of the high pressure end drops to a certain extent, when the pressure of the low-pressure end rises to a certain extent, the pressure control valve increases the piston stroke to improve the refrigeration intensity.
