R22 pressures.

At 318.5 PSI, the saturated temperature is 100°F. If you measure 118 PSI on the low-pressure side of the system, then you know that the saturated temperature of the refrigerant flowing through the middle of the evaporator coil is at 40°F. This is a useful number when combined with the temperature of the tubing near the pressure port. Refrigerant Pressure - Temperature Chart.
