Numbering Scheme in Sizing
When a valid route is loaded in the Sizing utility, the summary table populates the system data. The system internally assigns unique identification numbers to every duct or pipe sections and fitting elements within a section. The section numbering is the determined in order of the flow. The next consecutive section number is incremented by 1. The numbering follows internal scheme logical in the direction of flow. .
- When sorted Group By: Duct Section, the Duct Section column sorts the duct components within the section and summarises pressure loss values for each duct section. Clicking in the Duct Section column heading toggles the order of rows.
- When sorted Group By: Duct Element, the Duct Element column groups the components within the duct category. Clicking in the Duct Element column heading toggles the order of rows.
Clicking in either Duct Section or Duct Element cell highlights the corresponding duct section component in the geometry. The arrow in the leftmost column indicates currently selected duct section.
The duct elements within a duct section are identified by per their parent section number. The entire duct elements correspond to duct fittings and are numbered in sequence. These fittings are mapped with ASHRAE Fitting No., as detailed in Fitting Loss Coefficient Summary dialog.
The similar numbering scheme applies to Pipe Section, and Piping Element, in pipe system.
