R12 — Ph Chart Pdf- ((top))

R12 has unique thermodynamic properties. It operates at lower pressures than modern R134a or R404A. An is calibrated specifically to the critical temperature (233.6°F / 112°C) and boiling point (-21.6°F / -29.8°C) of pure Dichlorodifluoromethane. Using a chart for a different refrigerant will give you dangerous, inaccurate readings.

Connect A to B to C to D. You have now visually mapped your refrigeration cycle. If the line from C to D crosses the saturated liquid curve cleanly, your expansion valve is sized correctly. R12 Ph Chart Pdf-

Assume your evaporator is operating at . R12 has unique thermodynamic properties

An R12 Pressure-Enthalpy (P-h) chart—often found in PDF format for engineering use—is a graphical tool used to analyze the thermodynamic performance of refrigeration systems using R12 ( CCl2F2cap C cap C l sub 2 cap F sub 2 Using a chart for a different refrigerant will

Always verify that the R12 you are using is legally reclaimed or recycled. Production of new R12 is illegal in most countries. Follow all local environmental regulations regarding refrigerant handling.

To use the chart effectively, one must understand saturation. A refrigerant like R12 "boils" (evaporates) at a specific temperature when it is at a specific pressure.
