An evaporative cooling system was designed and evaluated. The system utilized high pressure fog nozzles mounted on a movable frame which travelled the width of a greenhouse bay. The system effectiveness (measured as absolute cooling and spatial temperature uniformity) as influenced by the spraying rate, the rate of frame movement and the greenhouse volume air change rate was determined. Effectiveness values ranged from 50 to 70% with instantaneous temperature reductions as large as 9 degree C.
