Experimental study on thermal performance and pressure drop of a cooling tower

Cooling towers are equipment devices commonly used to dissipate heat from power generation units, water‐cooled refrigeration, air conditioning and industrial processes. Experiments were carried out on the heat transfer laboratory at Islamic Azad University of Mashhad in Iran. In this study outlet water temperature was used in determining experimentally the thermal performance of the cooling tower. Outlet water temperature decreases as air mass flow rate increases, the outlet water temperature increase as the wet bulb temperature increases, the outlet water temperature decrease as mass flow rate ratios increases, the water outlet temperature decreases as volume of tower increases, the outlet water temperature decreases as the pressure drop increases.
