THERMAL PERFORMANCE OF A ROOM WITH AIR DISPLACEMENT VENTILATION SYSTEM.

Author(s) : KOOI J. van der, CHEN Q.

Summary

THE USUAL COOLING LOAD PROGRAMS CAN ONLY BE USED FOR ROOMS WITH A UNIFORM TEMPERATURE DISTRIBUTION. WITH A NEW PROGRAM IT IS ALSO POSSIBLE TO CALCULATE SITUATIONS WITH A VERTICAL TEMPERATURE STRATIFICATION. WITH THIS PROGRAM, THE HOUR-BY-HOUR COOLING/HEATING LOADS HAVE BEEN CALCULATED FOR A ROOM WITH A DISPLACEMENT VENTILATION SYSTEM (WITH TEMPERATURE STRATIFICATION) AND A WELL-MIXED SYSTEM. WITH AN ENERGY CALCULATION PROGRAM THE YEARLY ENERGY CONSUMPTION OF BOTH SYSTEMS HAVE BEEN CALCULATED. FOR THE SAME INLET AIR TEMPERATURE, THE ENERGY COSTS OF THE DISPLACEMENT VENTILATION SYSTEM ARE ABOUT 16% LOWER THAN THE WELL-MIXED SYSTEM.
