Abstract
In this paper, performance of two types of cellulose cooling pads (5090 and 7090) which were made from corrugated papers has been investigated. They were tested in a sub sonic wind tunnel. The pads areas are 0.35× 0.35 m2 with 50, 100 and 150 mm thicknesses. Humidity variation, Pressure drop, effectiveness and evaporated water have studied for several inlet air velocities. The results show that overall pressure drop and amount of evaporated water increases by increasing the inlet air velocity and thickness in both types of pads. On the other hand, effectiveness and humidity variation decreases by increasing inlet air velocity. When compared with local materials the effectiveness of the pads in decreasing order of magnitude is Cellulose>Aspen>Khus pad. Cellulose pad effectiveness depends on thickness of pads as well as inlet velocity. Further more with proper maintenance, cellulose pads can be used for many years. This study is useful for making opportunities in residential buildings to use cellulose cooling pads instead of aspen pads in conventional desert coolers.
