Effect of Discharge Pressure:
In real practice, the discharge pressure (or condenser pressure) enhance because of frictional resistance of flow of the refrigerant. Let us assume a theoretical vapour compression cycle l-2-3-4 while the discharge pressure enhance from pD to pD? as indicated on p-h diagram in fig. resulting in increased compressor work & diminished refrigeration effect.
