Control Systems

Direct Digital Control systems for HVAC use a centralised computer network to control and manage energy and perform system diagnostic functions. A DDC Energy Monitoring and Control System (EMCS) accepts analogue, discrete, and digital input from remote sensors and devices, processes the data, and then controls remote mechanical equipment. These can replace conventional pneumatic or electromechanical HVAC control systems and have the advantage of providing more accurate control because it reduces the drift, maintenance and recalibration problems common with pneumatic control systems. Quality control, production, research, and maintenance will all benefit from the increased information flow when it is properly managed.

The overall impact of a DDC system upon the energy efficiency of a research laboratory is considerable and includes a broad range of positive benefits. Some impacts have a direct energy influence, e.g., precise temperature control, while others have indirect energy consequences, e.g., consumption reporting.
