These factors include corrections for liquid refrigerant density and net refrigeration effect, and are based on an average evaporator temperature of 0°F with a maximum 7°F Change in
Superheat. 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 insignicant.

Note: Standard capacity is rated at 100 ºF liquid inlet and 40 ºF evap temperature; with 160 Psi pressure drop across TXV per ARI-750-2001.
These ratings assume vapor free liquid entering the thermal expansion valve.
