The pressure-enthalpy diagram and the basic process
1. The pressure-enthalpy diagram (log ph diagram)
The thermodynamic properties of a refrigerant are often represented in a pressure-enthalpy diagram. Here, the logarithm of pressure is plotted as a function of enthalpy, with the various thermodynamic properties as parameters (see Figure 1). The main components are:
◆ The thick line (boiling line)
