Fundamentals: Pressure enthalpy
The pressure enthalpy is a useful tool not only for explaining and understanding refrigeration cycles, but also for analysing the performance of refrigeration systems. It can predict refrigeration system conditions, such as the pressure and temperature for the refrigerant at various locations within the system. It can also be used to demonstrate the effects of system changes to these conditions.
