About R-134a
R-134a is a low-pressure HFC used in chillers, refrigeration, and automotive AC.
The chart shows saturation temperature in °F at gauge pressure (PSIG), sea level, every 10 PSI from 0 to 300 PSIG. Readings between rows are linearly interpolated, the same way FieldLoom does it on the job.
Use it with the superheat and subcooling calculators, or see all refrigerants.
Questions
What pressure is 40°F for R-134a?
About 29 PSIG.
What pressure is 100°F for R-134a?
About 101 PSIG.
Are these pressures gauge or absolute?
Gauge pressure (PSIG) at sea level, the same as your manifold reads.
