h, log p diagram (Introduction) YouTube
The log p,h-diagram displays the pressure p logarithmically over the specific enthalpy h. this diagram is used first of all in refrigeration engineering. A calculation (simulation or validation) has to be performed before creating the diagram. log p,h-diagrams are called through the menu command „Extras à Diagrams à log p,h-diagrams…".

The pressure-enthalpy diagram (log P/h diagram) is a very useful tool for refrigerant technicians. First, an explanation of how the diagram is built up is given, and then its use is describ ed. Figure 2.1 shows the principle of a log P/h diagram, and indicates the refrigerant's various thermodynamic states.

Figure: h-log(p) diagram of the NH3 GCHP. # The resulting fluid property diagram is shown in the figure above. It can easily be seen, that the evaporator slightly overheats the working fluid, while it leaves the condenser in saturated liquid state. The working fluid temperature after leaving the compressor is quite high with far more than 100.

2.4 The complex cycle in a log Ph diagram. In reality, the pressure drops that occur in the evaporator, condenser and piping must be considered. There are also mechanical and electrical losses in the compressor. The consequences are increased operational and maintenance expenses. However, some measures can be taken to minimize the costs.

A p-h diagram indicates the fluid state at key points during a thermodynamic cycle. The plot units are MPa for pressure, kJ/kg for specific enthalpy, and K for the temperature contours. Each numbered point on the diagram indicates the fluid state after a dynamic process in the refrigeration cycle: Cool vapor at low pressure
