Insulation and lining graphic overrides
Although lining and insulation can be added only as instance parameters,
the workflow for using this tool is much easier than in most previous
releases. Even so, if the entire system requires lined or insulated ducts, you
have to select all ducts for the system and then specify the insulation or
lining required.
Duct sizing works only where air terminals, ducts, duct fittings, and
mechanicalequipmentareseamlesslyconnectedwithnogapsandwherethe
equipment has a defined airflow. This airflow could be entered as part of the
initial analysis or subsequent manipulation of the objects.
Once a system is created, you can use the analytical tools to inspect the duct
system for airflow, pressure, and pressure loss. From the System Browser,
select the system you want to analyze (as shown in
Figure 10.43
)
.
Remember, you can also Tab-select the system. With the system selected,
click System Inspector on the ribbon. If the Inspector tool isn't available, it's
a clue that something is wrong.
