The refrigeration cycles can also be represented in a P-H diagram. Figure 5: P-H diagram representation of a dry refrigeration cycle Refrigerant fluid choice: We now turn our attention to the fluids. Usually, one tends to pick pL as low as possible, but not below atmospheric pressure. Thus, the refrigerant chosen needs to have a normal boiling ... Defined by a cycle of transfers into and out of a system, a cyclic process is described by the quantities transferred in the several stages of the cycle. The descriptions of the staged states of the system may be of little or even no interest. A cycle is a sequence of a small number of thermodynamic processes that indefinitely often, repeatedly returns the system to its original … The P-h diagram is another convenient diagram often used to illustrate the refrigeration cycle. The ordinary household refrigerator is a good example of the application of this cycle.

The refrigeration cycle in the log p-h diagram The refrigeration cycle in the log p-h diagram The real refrigeration cycle consists of the following changes of state: 1 - 2 polytropic compression on the condensation pressure (for comparison 1 - 2' isentropic compression) 2 - 2'' isobaric cooling, deheating of the superheated steam Most refrigeration cycles are typically represented by a pressure-enthalpy (P-h) diagram, which shows the phase changes of the refrigeration cycle and provides a graphical means of study. Horizontal lines on the P-h Chart are lines of constant pressure and vertical lines are lines of constant enthalpy or heat energy. The Refrigeration Cycle - Complete: Fig 5. In this final diagram of the refrigeration cycle we have introduced 3 new terms: Superheated, Saturated & subcooled. SUPERHEAT - Is an amount of heat added to refrigerant vapour beyond its boiling point. This ensures the refrigerant is in a gas state with no liquid present.
