Mechanical Equipment Components
Mechanical equipment comprises the components that make up the
majority of large- to medium-size plant objects for the mechanical designer.
From air conditioners (ACs) and air-handling units (AHUs) to air curtains
and heat pumps, these all provide the geometry and parameters associated
with HVAC design. As with all components, choosing the hosting type is
important. A level-hosted object cannot be exchanged for a face-hosted or
ceiling-hosted one.
Air Conditioning/Handling Units
The heart of the mechanical air system, the air-conditioning or air-handling
units, can start life as generic “boxes” with intake and exhaust. Although
basic in construction and with no manufacturer data attached, generic ACs/
AHUs can have the same number of parameters as more detailed families.
Similar in dimension and performance to generic ACs/AHUs, the concept
box can be swapped out during the detail design period for a more detailed
manufacturer or construction-issue family, or even for a set of families if
the AC/AHU unit has been constructed from its manufacturer's component
parts (see
Figure 10.4
). It is, however, entirely likely that the connectors in
this generic unit will not be in the correct location when the more detailed
manufacturer's family is loaded. This can mean some rework is necessary in
order to produce a more accurate model.
