This research is centered around the development and construction of a test apparatus for a counterflow evaporative cooler. The packing material utilized in the testing is coconut coir with wettability values of 300, 400 and 500 m2/m3. The experiments involve varying the air velocity. The study examined performance characteristics, including evaporation rates, cooler efficiency, coefficient of performance (COP) and energy consumption information, in relation to the standard Celdek 7090 packaging. The findings demonstrated that employing a coconut coir with optimal wettability resulted in a cooling efficiency and COP of 53.57% and 1.25, respectively. These values were slightly lower than those achieved with the usual Celdek 7090 packing. Coconut coir, as a biomass-derived material, possesses certain benefits that make it a suitable alternative for filling materials in evaporative cooling processes.
