ASHRAE A2L·PURE
R-32 Pressure-Temperature Chart
Pure difluoromethane (CH2F2, 100%). Standard saturation pressures across evaporator, suction, and condensing temperatures.
Single Saturation Curve
R-32 is a single-component pure refrigerant with zero glide. Saturation pressure is identical for liquid (bubble) and vapour (dew) phases.
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.
