What Is an HVAC DDC Control System?
Direct digital control for building HVAC systems refers to an automated process for controlling the functionality of the heating and cooling units. This “smart” technology can also encompass other mechanical and electrical systems, such as lighting and water heating, to provide an integrated resource management solution. A DDC setup delivers more precise control over the operation of these units, resulting in increased efficiency and lower energy costs.
How Does a DDC HVAC System Work?
A DDC system features a central computer workstation that serves as the control center. The building manager or maintenance supervisor can use the computer to set up specific temperature zones and operating schedules throughout the facility based on typical usage patterns and other factors at various times of the day and night.
A series of sensors monitors the temperature and humidity on a 24/7 basis and transmits the data back to the central workstation, which makes automatic adjustments to the HVAC units as needed.
