Capacity ratio [%]
Corrected pipe length
(c) Capacity correction
Cooling and heating capacity is lowered according to pipe length. Capacity can be obtained by referring to the capacity
curves below. When the diameter of gas pipe is one size smaller than standard diameter, cooling capacity is lowered com-
paring to the standard diameter. The lowered capacity can be obtained by referring to capacity curves for gas pipe which is
one size smaller than standard size.
Corrected pipe length (m) = actual pipe length (m) + number of bends x 0.3 (m)
