Abstract
Cooling by indirect evaporative system can be fashioned to reduce the external air temperature. This is characteristically accomplished in swine conveniences with evaporative cooling pads. As air is drawn through wet cooling pads, water is evaporated into the air causing the temperature to be reduced at the same time as increasing the moisture level. Indirect evaporative cooling techniques include roof spray and roof bond systems, earth cooling tubes. Night spray for example on roof surface cools water by evaporation and radiation to 5–8°C below minimum night air temperature. This cools the roof surface, and a temperature gradient is created between the inside and outside surfaces causing cooling of the building.
