However, in real applications this is limited by th High volumetric 4. (2) High speed. In order to determine a systems compression ratio, we must deal in absolute pressures, not gauge pressure readings, since a refrigeration system is a closed system, not open to atmospheric pressure. If you are thinking about air conditioning, it is often around 3:1 or 4:1. In this calculation, absolute discharge pressure is raised to 400 psia, essentially doubling it, to give the same 20:1 compression ratio. Low static compression/ high boost allows the compressor to move more air (g/sec) than high static compression/low boost before you hit the maximum limit where compression auto-ignition occurs.
