EXTENDING THE SUMMER COMFORT ENVELOPE WITH CEILING FANS IN HOT, ARID CLIMATES.

Author(s) : SCHEATZLE D. G., WU H., YELLOTT J.

Summary

THE PURPOSE OF THE STUDY WAS TO DETERMINE IF THE SUMMER COMFORT ZONE COULD INCLUDE CONDITIONS OBTAINED IN HOT, DRY CLIMATES WITH A COMBINATION OF EVAPORATIVE COOLING AND THE AIR MOTION OBTAINED WITH CEILING FANS. THE EVAPORATIVE COOLER CAN PROVIDE ACCEPTABLE COOLING FOR PORTIONS OF THE YEAR BUT IS NOT SATISFACTORY FOR PERIODS OF HIGHER WET-BULB CONDITIONS. THE STUDY WAS CONDUCTED ON 96 HUMAN SUBJECTS. IT SHOWS THAT VELOCITIES BETWEEN 0.46 AND 1.0 M/S THAT ARE PROVIDED BY A CEILING FAN CAN EXTEND THE TIME THAT A DIRECT EVAPORATIVE COOLER CAN BE USED FOR THERMAL COMFORT IN PHOENIX. WITH THE INDIRECT EVAPORATIVE COOLER, IT IS THEORETICALLY POSSIBLE TO PROVIDE COOLING FOR THE ENTIRE SEASON USING THE HIGHEST AIR VELOCITIES, WHICH WILL NOT BE ACCEPTABLE TO ALL PEOPLE.
