Saturation Pressure-Temperature Data for R22 (psig)*.
R22 PT chart describes the relationship between temperature and pressure. Namely, it tells you what is the pressure of R22 refrigerant gas at different temperatures. Example: What are R22 pressures on an 85-degree day? You simply consult the R22 RT chart below and see that at 85°F, the pressure of R22 is 155.7 psig. psig or ‘pounds per ...
R22 gas cylinder identification: light green. R2 status: no longer in active use, replaced with R458A. R22 and other common refrigerants is an odorless, colorless gas that will be liquid at sufficiently low temperature and/or high pressure. This chart is using outdoor ambient temperature.

Saturation Pressure-Temperature Data for R-22 (psig)* *Red Italics Indicate Inches of Mercury Below Atmospheric Pressure
Applications: Medium and low temperature commercial and industrial refrigeration; residential and commercial air conditioning. Performance: Industry standard choice for AC until 2010.
To get the correct saturation temperatures, an HVAC tech will read the pressure and temperature then use a temp pressure chart to see if a unit is operating correctly. The pressure-temperature relationship in a PT card is simply a chart listing the boiling temperatures of the refrigerant.
