Cooling / Heating Correction Factors
For Single Zone Wall Mounted Extended Piping 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 the corresponding cooling or heating
capacity correction factors as shown in the table below. 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.
