States that with TRAV systems, where control of the central fan is integrated with terminal controls, supply air static pressure is reduced whenever areas of the building are not experiencing peak design conditions. States that computer simulations based on typical office variable air volume applications have shown that as much as 50% of the required fan energy is saved by TRAV control strategy. In applying TRAV to buildings, a number of other new opportunities to further enhance the energy efficiency and improve the comfort/air quality conditions have also been developed. Lists some new HVAC control ideas developed for TRAV that have been successfully integrated into recent TRAV designs. Reviews their performance and presents conclusions about incorporating them in future direct digital control applications for typical buildings.
KEYWORDS: Air conditioning, variable volume air conditioning, controls, air terminals, energy conservation, designing, performance.
