CENTRAL FAN SYSTEM CONTROL
Figure 23 shows the net airflow balance for a building space and where the return air, outdoor air, and supply fan inlet meet. Assume that the return air damper is open, the relief air damper is closed, and the outdoor air damper is open enough to allow minimum design outdoor air to pass. When the outdoor and relief dampers open further and the return damper closes further, outdoor air increases above the minimum. These conditions are used for free cooling (economizer cycle control) and when minimum air must be greater than the difference between supply and return fan airflow rates.

PRESSURIZATION
Building pressurization and ventilation are important aspects of airflow control. A building or areas within a building can be pressurized for positive, negative, or sometimes neutral static pressure to control the flow of air from one area to another. A building can use positive static pressure to eliminate infiltration drafts, possible dirt, and contamination from outside sources. Areas within a building such as laboratories can use negative pressure to prevent contamination and exfiltration to adjacent spaces and zones. Proper building pressurization must also consider the effects of outdoor wind pressure and stack effect or vertical air differences.
