Roof cooling with intermittent water sprays
Effectiveness of sprays in combatting solar heat gain through roofs was investigated at Phoenix, Ariz, to determine quantitatively extent to which intermittent spraying could cool horizontal and tilted roofs under conditions of high irradiation and air temperature and low relative humidity; analysis of test results showed that under southwestern summer conditions intermittent sprays can effectively cool horizontal and tilted roofs; use of approximately 0.30 lb of spray water/ hr/sq ft of roof will reduce roof temperature to point where day-long average differential between roof and ambient air is close to zero.
