At saturation, liquid and vapor can coexist
R410A saturation properties are used for quick heat pump and air conditioning checks, evaporator and condenser estimates, pressure-temperature comparisons, and troubleshooting. Always verify final design values against manufacturer data and applicable refrigerant standards.
Reference
What the R410A values mean
Saturation pressure
The pressure at which R410A boils or condenses at the selected saturation temperature.
Liquid enthalpy
hf is the energy content of saturated liquid refrigerant at the saturation point.
Vapor enthalpy
hg is the energy content of saturated vapor refrigerant at the saturation point.
Specific volume
vg helps estimate vapor volume flow and compressor displacement requirements.
FAQ
R410A refrigerant questions
What is R410A refrigerant?
R410A is an HFC refrigerant blend widely used in residential and commercial air conditioning and heat pump systems.
Why is R410A pressure higher than many older refrigerants?
R410A operates at higher saturation pressures than refrigerants such as R22, so equipment, gauges, and service procedures must be rated for the refrigerant.
Can this table replace manufacturer refrigerant data?
No. Use this page for quick reference and early calculations. Final HVAC work should use manufacturer data, standards, and calibrated gauges.
