Thermal performance of wet cooling tower with grid fill

Abstract

Cooling towers are evaporative heat rejection devices, which take out the waste heat from a process to the atmosphere through the cooling of water by the ambient air. The cooling tower is basically a mixed heat exchanger. A spray zone, fill zone and a rain zone are three important zones from heat and mass transfer view in the cooling tower. Thermal performances of all these zones are obtained by experimental measurements due complicated heat and mass transfer phenomena in a cooling tower. The spray zone and fill zone was measured together. And the thermal performance of rain zone was evaluated.
