GENERAL
An HVAC system is designed according to capacity
requirements, an acceptable combination of first cost and
operating costs, system reliability, and available equipment
space.Figure 2 shows how an HVAC system may be distributed in
a small commercial building. The system control panel, boilers,
motors, pumps, and chillers are often located on the lower level.
The cooling tower is typically located on the roof. Throughout
the building are ductwork, fans, dampers, coils, air filters,
heating units, and variable air volume (VAV) units and
diffusers. Larger buildings often have separate systems for
groups of floors or areas of the building
