The graph shows the variations in the refrigerant’ pressure and
enthalpy during the entire thermodynamic cycle.
- from point (8) to point (4) the refrigerant is in the vapour phase
- from point (4) to point (5) the refrigerant is reduced from its vapour
phase to its liquid phase
- from point (5) to point (7) the refrigerant is in the liquid phase
- from point (7) to point (8) the refrigerant is reduced from its liquid
phase to its vapour phase
