ASHRAE A1·NEAR-AZEOTROPIC
R-410A Pressure-Temperature Chart
R-32 / R-125 (50% / 50% by mass). Standard saturation pressures across evaporator, suction, and condensing temperatures.
Single Saturation Curve
R-410A is a near-azeotropic blend with negligible glide (< 0.3 °F / 0.15 °C). A single saturation pressure column is standard for field service, charging, and SH/SC calculations.
Sea-Level Pressure Standard
psig = psia − 14.696 (standard atmospheric pressure at sea level). At higher elevations, adjust gauge manifold readings accordingly.
Reference only. Follow the equipment manufacturer's charging instructions and data plate.
