- The interface supports three line groups—MT suction, LT suction and liquid—and describes pressure-drop calculations using Darcy–Weisbach.
Field notes
The visible controls let users enter circuit temperatures, superheat, compressor capacity and target velocities, then add evaporators and pipe branches to a flow diagram. Additional settings include minimum pipe size, extra-length and connection margins, and insulation by line group. The page describes printable drawings and generated material lists; it does not provide evidence here of independent calculation validation.
