Gas Pressure saturation sizer
Calculate refrigerant pressure-temperature saturation points (P-T Chart)
Settings
Saturation Temp (°F)
40.2 °F
Corresponding saturation boiling point in Fahrenheit.
Saturation Temp (°C)
4.6 °C
Celsius metric temperature conversion value.
Standard Suction Side (Low)
118 - 143 psig (39°F - 49°F)
Typical evaporator pressure ranges under normal operation.
Standard Liquid Side (High)
318 - 418 psig (100°F - 120°F)
Typical liquid line saturation ranges under normal operation.
Refrigerant Characteristics (R-410A)
Modern high-pressure refrigerant for residential AC systems. Replaced R-22.
Antoine Saturation Formula: Calculations are performed using the temperature-explicit version of the Antoine equation parameterized by Danfoss controllers:
Te (°C) = A2 / (Ln(Pe) - A1) - A3
Where pressure (Pe) is expressed in absolute bar and temperature (Te) in Celsius. Absolute pressure is adjusted for standard atmospheric pressure (14.696 psi) to display gauge readings (psig) commonly used in manifold service gauges.
