The goal of this study was to determine whether locally accessible luffa, straw, and sackcloth fiber pads could replace traditional celdek pads in cooling systems, particularly in greenhouses. The study's goals were to find out how different evaporative pad types and thicknesses, as well as climatic elements, including temperature, pressure drop, relative humidity, and air velocity, affected the greenhouse's ability to cool effectively. The outcomes showed considerable effects of various pad materials on greenhouse cooling effectiveness. The average saturation from the luffa pads was 78.5%, while the average saturation from the straw fiber and sackcloth fiber was 72% and 66.6%, respectively. On the contrary, the celdek pads produced an average saturation of 75.60%. The 300 mm thick pad had a highly significant impact on cooling efficiency, lowering the temperature and slightly raising the relative humidity while also absorbing more water and lowering the pressure. The outcomes also showed that the amount of water had a big impact on cooling effectiveness. Moreover, there was a strong correlation between air velocity, cooling effectiveness, and pressure; as air velocity rose, cooling efficiency declined and pressure increased across the cooling pads. The current study established a negative correlation between temperature and cooling effectiveness. Lastly, the study proved that the luffa pads are a better alternative to the conventional celdek pad as they produced the best results than the other cooling pads.
