Topology Description of HVAC Systems for the Automatic Integration of a Control System Based on a Collective Intelligence System

This paper proposes a collective intelligence system (CIS) that uses a decentralized and self-organizing approach to build a smart control system for HVAC equipment. Using standard control units, the control system can automatically identify the building space, HVAC equipment, sensors and actuators in the identified spaces without human intervention. To support the automatic system integration and relation identification, a novel topology description based on graph theory of the building space and HVAC system is proposed. The description method was examined by its application to a typical building layout with a water distribution system and a ventilation system. The potential of using the CIS for HVAC system control is further explored, and the benefits are discussed.
