Abstract

In the present performance parameters is determined for the varied operating conditions using mathematical modelling. Outlet humidity ratio, Dry bulb temperature (DBT), cooling efficiency and cooling effect have been predicted by varying the air velocities, inlet DBT, inlet relative humidity (RH) and pad thickness for three different wettability of Celdek packing. Predicted results revealed that cooling effect, saturation efficiency, �DBT and humidity ratio are found to be increasing with the increase in pad thickness and wettability of the material. An increase in the inlet air flow rate and RH resulted in a decrease in �DBT, humidity ratio and cooling efficiency. The maximum perfor�mance of �DBT, �RH, saturation efficiency and cooling effects have been observed for Celdek 7090 and are equal to 6°C, 55%, 90% and 7000 Watts for the thickness of 0.3 m, wettability of 630 m2/m3. Wettability of 630 m2/m3 & thickness 0.3 m gave maximum performance.
