Glossary. 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.

The blue line on the left of the bubble represents the 100% saturated liquid line, How to Read a Pressure-Enthalpy Diagram In chemical engineering, it is often necessary to know how properties like pressure, enthalpy, volume, and entropy relate to each other at a certain temperature. A Pressure-Enthalpy Diagram provides this information but can be cryptic to decipher. What you need to know: Liquid/vapor dome region Pressure-Enthalpy Diagram for Water - Ohio University The most common type of pressure-enthalpy diagram is shown in Figures 1A through 1H. They show all five properties for a specific refrigerant in present-day use. Pressure is listed along the right and left borders in psia. Horizontal lines are constant pressure lines. 4.88 pressure-enthalpy diagram for ethylene 10 100 1000 10000 700 750 800 850 900 950 1000 1050 1100 1150 1200 enthalpy, Btu/lb pressure (psia) 160 F 140 F 120 F 100 F 80 F 60 F 40 F 20 F 0 F 20 F 240 F 200 F 100 F 0 F 100 F 200 F 300 F liquid liquid-vapor two phase vapor psia = pounds per square inch absolute When the enthalpy of this overall chemical equation is calculated, the enthalpy of the second intermediate equation is halved and has its sign changed Consider the following enthalpy diagram.
