Pressure Levels
Pressure on suction and discharge openings for compressor also affect the load. The more pressure difference, the less power. When considered individually, the suction pressure has a greater impact on compressor capacity than the discharge pressure. In a comfort air conditioning system under normal operating conditions, differential pressure, which causes 1F reduce the amount of saturated refrigerant temperature at the compressor suction reduces its capacity is about 2%. On the other hand, the increase in pressure at the compressor discharge, which results 1F increase the saturation temperature leads only 1% decrease in productivity of the compressor.
Compressor suction pressures affect devices that control the performance of the compressor, for instance, cruise control, cylinder unloading, Cycling multiple compressors. At a given load, reduction of compressor output methods, as a rule, increase the suction pressure. Condenser pressure, control techniques affect the discharge pressure of the compressor. On a given workload, head pressure tends to increase of discharge pressure...
