Art Cool Premier Wall Mounted Engineering Manual
Cooling / Heating Correction Factors
For the Art Cool Premier system, 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 Figure 5 and Figure 6. Multiply the correction factors by the cooling or heating capacity obtained from the capacity table using
design conditions. The resultant is the NET cooling or heating capacity.
