Cellulose pad panels are commonly used in air cooling systems, despite some problems. Several studies have shown the possibility of using alternative materials such as expanded clay (Cinasita). Earlier studies have shown that this type of clay has required characteristics of a good porous material, thus can be an economical replacement for cellulose. The present study was done to determine suitable size and thickness of porous expanded clay pads, which could provide better cooling efficiency in acclimatized environments. Expanded clay pads with granulometry 1 (reference to grit 1) and 77 mm in thickness showed good efficiency for evaporative adiabatic cooling at the wind speed between 0.44 and 1.28 m/s.Downloads
