(3) Capacity correction
Cooling and heating capacity is lowered according to the piping length. Capacity can be obtained by referring
to the following capacity curves.
When the diameter of the gas pipe is smaller than the standard size, cooling capacity is lowered comparing to
the operation using the standard diameter pipe.
The lowered capacity can be obtained by referring to the capacity curves for gas pipe which is one or two size
smaller than standard size.
Corrected pipe length (m) = actual pipe length (m) + number of bends
