Refrigerant Pressure-Temperature Charts
Each page converts between a refrigerant’s saturation pressure and temperature, in either direction, for use when reading gauges. The general chart lets you choose a refrigerant; the individual pages cover R-22, R-32, R-134a, R-290, R-404A, R-407C, R-410A, R-448A and R-454B. The superheat calculator uses a gauge pressure and line temperature to get superheat or subcooling.
