Page 29: Refrigerant Liquid Temperature Valve Capacity Multiplier Correction Factors
These factors include corrections for liquid refrigerant density and net refrigerating effect and are based on an average 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. © 2016 Emerson Climate Technologies, Inc. -
