These factors include corrections for liquid refrigerant density and net refrigerating effect, and are based
on an evaporator temperature of 0°F. However, they may be used for any evaporator temperature from
0°F to 40°F since the variation in the actual factors across this range is insignificant.
TEV Capacity = TEV Rating x CF Liquid Temperature – Example: Actual capacity of an HCE-3 using R-410A
at a 40°F evaporator, 160 psi pressure drop across the TEV, and a 80°F liquid temperature entering the
TEV = 3.00 (from rating chart) x 1.16 (CF liquid temperature) = 3.48 tons

R-410A 1.73 1.59 1.44 1.30 1.15 1.00 0.84 0.65
These factors include corrections for liquid refrigerant density and net refrigerating effect, and are based
on an evaporator temperature of -15°C. However, they may be used for any evaporator temperature from
-15°C to 5°C since the variation in the actual factors across this range is insignificant.
TEV Capacity = TEV Rating x CF Liquid Temperature – Example: Actual capacity of an HCE-3 using R-410A
at a 5°C evaporator, 11 bar pressure drop across the TEV, and a 30°C liquid temperature entering the
TEV = 10.5 (from rating chart) x 1.15 (CF liquid temperature) = 12.1 kW
