Compressor Efficiency - an overview | ScienceDirect Topics

In a positive displacement compressor the gas is transported from low pressure to high pressure in a device that reduces its volume and thus increases its pressure. The most common type of positive displacement compressors are reciprocating and rotary (screw or vane) just as was the case for pumps.

3.4 Compressor performance - SWEP

High temperature in the evaporator is eq uivalent to high pressure and high vapor density. This means that 1 kg high-pressure vapor occupies less volume than 1 kg low-pressure vapor. In a refrigerant system, the mass flow of high-pressure vapor into the compressor is therefore larger at each displacement than the mass flow of low-pressure vapor.

Compressed Air Controls | Compressed Air Best Practices

Precise control systems are able to maintain lower average pressure without going below minimum system requirements. A rule of thumb for systems in the 100 psig range is for every 2 psi increase in discharge pressure, energy consumption will increase by approximately 1 percent at full output flow (check performance curves for centrifugal and two-stage lubricant injected rotary screw compressors).

Low Pressure Ratio - an overview | ScienceDirect Topics

The requirements for Range, Pressure ratio, and Performance vary greatly between applications. While pipeline compressors typically operate at low pressure ratios (say, from 1.1 to 1.7), other applications may require significantly higher ratios. In gas gathering, we may find pressure ratios of 25.
