Mapping of Components Types
When a networked duct/pipe route system is loaded in the
System Sizing utility, the summary table populates sections and all
elements/fittings associated in the paths. These component types are mapped
internally with
Mechanical discipline fittings database. As a
default, the current preferred fitting types set in the AutoFitting preferences
are assigned to fitting elements. The Elements in the summary table are those
connecting fittings used to link paths. Besides standard fittings like
transition, bends and takeoffs used in duct / pipe sections, the route may have
inline silencers and dampers in the design. When selected from the database,
these fittings are mapped for their types and assigned their equivalent ASHRAE
Fitting number.
As seen in the Fitting Loss Coefficient Summary table, the entire
duct fittings in the system are checked for their characteristics in the
database and assigned their types. Fitting types within a section are grouped
under Fittings cell under Duct Element column in Duct Sizing Summary table, and
are listed in order.
The mapping also applies to pipe elements and piping fittings in pipe sections when working with pipe system.
