The research Parametric analysis and improvement of mist fan operation for indoor cooling redesigned a mist fan nozzle arrangement to ascertain the effects of nozzle arrangement on cooling efficiency while emphasizing on temperature distribution, velocity distribution and water mass fraction distribution was accomplished. A comparative analysis was carried on 5 different nozzle arrangement to determine the arrangement with the highest efficiency. An experimental setup of a mist fan with a nozzle size of 10µm, 50 µm and 100 µm but varying arrangement. Temperature readings was taken at varying velocities. The analysis was done experimentally and also using computational fluid dynamics. The result shows a cooling efficiency of 66%, 67%, 68%, 70% and 63% for nozzle arrangement 1,2,3,4 and 5 respectively. The same experiment was carried out physically using the same values. Nozzle 4 arrangement shows a temperature reduction of 303.4K which lesser when compared with the 4 other nozzles which temperature is higher. The experimental and CFD result shows 96% correlation.
