Refrigeration Cycle Coefficient of Performance
Prepared by M. D. Normand and M. Peleg
This Demonstration illustrates how to calculate the coefficient of performance (COP) of an ideal mechanical refrigeration system using a pressure-enthalpy diagram. Use the sliders to set the enthalpies of the refrigerant at the four principal points in the cycle. The COP value is displayed above a schematic drawing of the mechanical refrigeration system that shows where energy enters and leaves and the refrigerant's flow direction. A plot of pressure versus enthalpy for the selected cycle is shown below the drawing. |
