Compressor

The compressor does work on the freon gas compressing, it from the low pressure, low temperature inlet gas to the high pressure, high temperature outlet gas. Thermometers and pressure gauges at these locations permit the state change across the compressor to be determined.

The work required by the compressor is provided by an electric motor. The indicating watt meter shows the power supplied to the electric motor. How does this relate to the work done on the freon by the compressor? How would you determine the efficiency of the electric motor and the efficiency of the compressor pump? Is heat added to the freon in the compression process? Can you verify this by consulting the pressure/enthalpy or Temperature/ entropy charts for the freon working fluid?
