TEST HUT VALIDATION OF A MICROCOMPUTER PREDICTIVE HVAC CONTROL.

Author(s) : SHAPIRO M. M., YAGER A. J., NGAN T. H.

Summary

NORMAL HVAC CONTROLS PREVENT USE OF THE BUILDING MASS AS A THE RMAL STORAGE FOR NIGHT FAN COOLING OR INTERNAL GAIN HEATING BY KEEPING THE MASONRY AT A CONSTANT TEMPERATURE. A DIURNAL ROOM TEMPERATURE SWING OF 4 K (4 DEG C) HAS LITTLE EFFECT ON COMFORT, BUT ALLOWS LARGE ENERGY SAVINGS. A MICROCOMPUTER CONTROL THAT PROVIDES SUCH TEMPERATURE SWINGS WAS DEVELOPED AND VALIDATED BY USE IN A MONITORED TEST HUT FOR 18 MONTHS. GOOD COMFORT WAS MAINTAINED. ON SOME NIGHTS, TOO MUCH FAN PRECOOLING COULD CAUSE THE PURCHASE OF HEATING THE NEXT DAY. THIS WASTE WAS PREVENTED WITH A CALCULATION USING OUTDOOR AND INDOOR TEMPERATURES PREDICTED 24 HOURS IN ADVANCE.
