Project Summary

The commercial sector uses variable air volume systems to provide more efficient heating, cooling, and ventilation than constant volume systems. To function properly and efficiently, these systems must maintain a balance of fan and VAV box control which supplies only the needed air and heat transfer to the building HVAC zones. VAV boxes are not generally set to operate as efficiently as they could in low flow conditions due to a lack of solid information about the interaction of the box and its controller. This work is intended to evaluate how low VAV boxes can be stably controlled at low flow rates. For more information, please contact the sponsoring organization.
