WebJan 14, 2024 · On a pressure-enthalpy diagram of the ideal refrigeration cycle, you’ll notice that the bottom edge of the figure will have a horizontal line. This line represents the evaporation phase. The pressure remains low and constant while the enthalpy rises. WebMollier charts are also called Pressure-Enthalpy diagrams. Pressure is shown on the verticle axis, enthalpy is on the horizontal axis. ... The series of graphics above shows how the refrigeration cycle is graphed onto the pressure-enthalpy chart and goes into details about how certain parameters can be determined from the chart.

Pressure-enthalpy diagram of a real refrigeration cycle Figure 3 shows the pressure-enthalpy diagram of a real refrigeration cycle. The key difference between the real cyclic process and the ideal cyclic process is that compression is not isentropic. Thus more work must be expended at the compressor to achieve the same final pressure.
