This study investigates the performance of an evaporative cooling system equipped with a porous ceramic cooling pad, focusing on the effects of inlet air temperature, air velocity, and pad usage on cooling effectiveness. Experimental data were collected for varying inlet temperatures (30–38°C) and air velocities (0.1–1.7 m/s) to evaluate system behavior under different operating conditions. The results show that as the inlet air temperature increases, both effectiveness and temperature drop rise, indicating improved evaporative performance in hotter ambient conditions. Furthermore, the comparison between systems with and without a cooling pad reveals that the ceramic pad provides superior cooling, achieving a maximum temperature drop of 11.9°C at a moderate air velocity of 0.5 m/s. This enhanced performance is attributed to the pad’s high surface area and water absorption capacity, which promote effective heat and mass transfer. However, excessive airflow reduces contact time and slightly decreases cooling efficiency. Overall, the findings confirm that integrating a ceramic ring-based cooling pad significantly improves the thermal efficiency and energy-saving potential of evaporative cooling systems, making them a sustainable and eco-friendly alternative to conventional air-conditioning technologies.
