Résumé

Cooling towers are increasingly used in buildings as a component of environmental cooling systems. When compared with industrial towers, cooling towers with lower capacities and smaller dimensions can be used for this application, with inlet water temperatures ranging from 22 to 25 °C. Correlations for heat and mass transfer coefficients were obtained experimentally for a small-size indirect cooling tower, with a nominal cooling capacity of 10 kW. A detailed analysis of the mass transfer coefficient and spray heat transfer coefficient correlations was made, including the effect of the error in the evaluation of tower efficiency. The new correlations were compared with existing ones and results of their application to a simplified cooling tower model were shown.
