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 -40°F to 40°F
since the variation in the actual factors across this range
is insignificant.
TEV Capacity = TEV Rating x CF Liquid Temperature x CF Pressure
Drop — Example: Actual capacity of a nominal 2 ton R-22 Type S valve
at 20°F evaporator, 100 psi pressure drop across the TEV, and 90°F
liquid temperature entering the TEV = 2.18 (from rating chart) x 1.06
(CF liquid temperature) x 0.89 (CF pressure drop) = 2.06 tons.
Q R-422D can be used in a system with R-22 valves, but the TEV capacity will be reduced. Please verify valve capacity will handle system load.
