K-23738 5/10 DuPont™ ISCEON® MO99 Pressure-Enthalpy Diagram DuPont™ ISCEON® MO99™ (R-438A)(Engineering Units) Pressure-Enthalpy Diagram (SI Units) Pressure Enthalpy Diagram. A simplified pressure-enthalpy diagram is shown below, describing this information. The liquid region is also known as the sub-cooled region. In this region there are vertical temperature lines, which increase as enthalpy is increased. Figure 8 is a simplified P-H diagram illustrating the constant temperature lines. 2019-04-14 Thermodynamic Properties of DuPont™ Freon® 12 (R12) SI Units Tables of the thermodynamic properties of DuPont™ Freon® 12 (R-12) have been developed and are presented here.

SI units. Table A-5 — Superheated Vapor Properties of Ammonia — SI Units using REFPROP (Version 7.0) with 0°C datums of 200 kJ/kg enthalpy and 1.000 kJ/kg-K entropy. SI units. The following diagrams are also included: Pressure-Enthalpy Diagram — IP Units Understanding the P-H Diagram On the P-H diagram, pressure is indicated on the r13a4 and enthalpy is indicated on the x-axis.

The enthalpy diagrams are very useful specially when calculating Heat required or Work needed for processes!You will love this ones later!Check out the Therm The pressure-enthalpy diagram (log P/h diagram) is a very useful tool for refrigerant technicians.
