Understanding Schedules 231
9.4 HVAC SCHEDULES.
There are many different types of HVAC schedules, which may include air-handling units, fan-coil units,
chiller schedules, etc. These are prepared by the mechanical consultant. HVAC systems are typically ei-
ther self-contained package units or central systems. Package units include roof top systems, air-to-air
heat pumps, and air-conditioning units for rooms. Central systems usually consist of a combination of
central-supply subsystem and multiple end-use zone systems (fan systems or terminal units). Figures
9.8A and B show examples of different types of HVAC schedules.
Figure 9.8A A simple example of an air-handling-unit schedule. Notice the significant number of notes that
accompany the schedule. These are critical to a proper understanding of the requirements.
