COMPARISON OF CONVENTIONAL MIXING AND DISPLACEMENT AIR CONDITIONING AND VENTILATING SYSTEMS IN UNITED STATES COMMERCIAL BUILDINGS.

Author(s) : SEPPANEN O. A.

Summary

THE PURPOSE OF THE STUDY WAS TO EVALUATE DISPLACEMENT AIR DISTRIBUTION SYSTEMS AND COMPARE THEIR PERFORMANCE TO THE PERFORMANCE OF TRADITIONAL VARIABLE-AND CONSTANT-AIR FLOW SYSTEMS IN US OFFICE BUILDINGS. ENERGY CONSUMPTION, AIR QUALITY, THERMAL SATISFACTION, AND THE COST OF THE SYSTEMS WERE CALCULATED FOR 3 BUILDING ZONES (SOUTH, NORTH, AND CORE). THE RESULTS INDICATE THAT DISPLACEMENT SYSTEMS GENERALLY YIELD SUPERIOR AIR QUALITY AND THERMAL COMFORT COMPARED TO CONVENTIONAL SYSTEMS WITH AIR RECIRCULATION. THE ENERGY CONSUMED BY DISPLACEMENT SYSTEMS WITH HEAT RECOVERY OR VARIABLE-AIR-VOLUME FLOW CONTROL WAS SIMILAR TO THE ENERGY CONSUMPTION OF CONVENTIONAL AIR DISTRIBUTION SYSTEMS OPERATED WITH RECIRCULATION.
