The function of the compressor1

The displacement of a fixed displacement compressor increases proportionally with the increase of engine speed. It cannot automatically change the power output according to the cooling demand and has a significant impact on engine fuel consumption. Its control is generally achieved by collecting temperature signals from the evaporator outlet. When the temperature reaches the set temperature, the compressor stops working. When the temperature rises

When the pressure in the pipeline is too high, the compressor stops working. 2. The variable displacement compressor can automatically adjust the power output according to the set temperature. The air conditioning control system does not collect temperature signals from the evaporator's m air outlet, but instead controls the compression ratio of the compressor based on pressure changes in the air conditioning pipeline to automatically adjust the temperature of the m air outlet. During the entire refrigeration process, the compressor is always working, and the adjustment of refrigeration intensity relies entirely on the pressure regulating valve installed inside the compressor to control it. When the pressure at the high-pressure end of the air conditioning pipeline is too high, the pressure regulating valve shortens the piston stroke inside the compressor to reduce the compression ratio, which will lower the refrigeration intensity. When the pressure at the high-pressure end drops to a certain level and the pressure at the low-pressure end rises to a certain level, the pressure regulating valve increases the piston stroke to improve the refrigeration intensity.
