Line Sizing
To determine the appropriate outside diameter for field installed liquid and suction
lines, it is first necessary to establish the equivalent length of pipe for each line. It is
also necessary to know the capacity (tons) of each circuit. Circuit capacities for each
RTAC unit are listed in the General Data Tables in Section1.
