Summary

THIS ARTICLE PRESENTS THE RESULTS OF A JOINT RESEARCH. THE FOLLOWING CONCLUSIONS CAN BE DRAWN: 1) DYNAMIC HVAC OPERATING STRATEGIES THAT WILL REDUCE ENERGY CONSUMPTION CAN BE IDENTIFIED THROUGH SIMULATION TECHNIQUES ; 2) THE EFFECT OF THE TIME BETWEEN CONTROL DECISIONS WAS EVALUATED. THE RESULTS SHOWED A 3 TO 4% ENERGY SAVINGS FOR A SYSTEM OPERATING UNDER DYNAMIC CONTROL, AS OPPOSED TO A SYSTEM IN WHICH CONTROL DECISIONS WERE MADE ON AN HOURLY BASIS. A MAXIMUM OF 7% IS POSSIBLE ; 3) USING AN OPTIMAL CONTROL STRATEGY, CHOSEN TO MINIMIZE ENERGY CONSUMPTION AT EACH OPERATING CONDITION, AN OVERALL ENERGY USE REDUCTION OF 8.7% TO THE CURRENT STRATEGY IS POSSIBLE. COMPARED TO OPERATION WITH FIXED SET POINTS, A REDUCTION OF 19% IS POSSIBLE ; 4) POTENTIAL ENERGY SAVING HVAC OPERATING STRATEGIES WERE IDENTIFIED AND RELIABLE EQUIPMENT MODELS WERE DEVELOPED. E.W.S.
