Cooling / Heating Correction Factors
For the Single Zone High Efficiency, Single Zone Standard and Single Zone Extended Pipe systems, calculate the equivalent length of the
liquid line from the outdoor unit to the indoor unit. Also, determine the elevation difference of the indoor unit above or below the outdoor unit.
Find corresponding cooling or heating capacity correction factors as shown in Figures 17-22. Multiply the correction factors by the cooling or
heating capacity obtained from the capacity tables using design conditions. The resultant is the NET cooling or heating capacity.
