Effect of Condenser Pressure:
In this case, the refrigeration effect is decreased through an area on the T-S diagram (fig 6) under the procedure 5-5?. At the similar time, the condenser work enhance by an area 2-2"-4'-4 compared to the regular cycle. Therefore, the COP & refrigeration effect are decreased compared to the ideal cycle. Furthermore, the work input has enhanced but is somewhat less than the enhanced while there is a modification in the evaporator pressure.
The effects of decreased evaporator pressure & increased condensers pressure are simply seen in Fig b1 and c on p - h diagrams respectively.
