Connections to both AC units and VAV boxes can include heated- and
chilled-water services and electrical for connecting to water and electrical
systems (see
Figure 10.7
). Also note the connector labels in this view, which
allow easier identification of connections and their flow direction, where
applicable. These symbols also double as a shortcut to start creating ducts
from the connector; just click the icon to start.

Heating and Cooling Elements
Heating coils, chilled-water coils, or reheat coils can be shown as part of
the equipment or provided separately. They can also be duct mounted.
Generally for FCUs, heat pumps, and most ACs/AHUs, the coil connections
would be built into the equipment, but for a built-up AHU or for a VAV
that may or may not include reheat, providing a coil separately can make it
easier to swap out without changing the entire family. Duct-mounted coils
need to be made adjustable to duct size and coil width (determined by the
number of rows) and will need to have the pressure drop provided from the
manufacturer's data.
