Airflow Tracking Control
In airflow tracking (Fig. 29) control, the return fan airflow is reset based on the relationship between supply and exhaust fan airflows. That relationship is usually a fixed difference between the supply total airflow and return plus exhaust total airflow, but it can also be a percentage of supply total airflow. When duct layout prevents measuring of total airflow from one flow station, measurements in multiple ducts are totaled. This technique is usually higher cost, especially when multiple flow stations are required. Airflow tracking control and direct building static control are preferable to open-loop control. Proportional plus integral control is necessary for accurate operation.

INTRODUCTION
This section describes control applications for air handling systems commonly found in commercial buildings. The basic processes such as heating, cooling, humidification, dehumidification, and ventilation are presented individually then combined into typical air handling systems. A discussion covering requirements for effective control is also included to provide guidelines for the design of the actual air handling systems with the related controls. Examples are based upon digital control systems. These digital control strategies may not be practical with other forms of control, and may not be possible with all digital controllers or by all digital controller programmers.
