Abstract


Achieving optimal contact between air and droplets is pivotal in direct evaporative cooling systems. This study presents an experimental analysis of spray cooling effectiveness in spray chambers utilizing pressure-swirl nozzles and impingement atomizing nozzle. Through the analysis of experimental data related to heat and mass transfer, the study reveals that if an optimal water supply pressure is identified, increasing the water flow rate does not necessarily enhance cooling performance. Furthermore, the study explores the impact of dry-bulb and wet-bulb temperatures of the air, as well as nozzle arrangement, on the determination of the optimal water supply pressure.
