Abstract

Tujuan dari peneltian ini adalah menganalisa karakteristik dari Cooling Tower tipe Force Draft. Penelitian ini menggunakan miniatur Force Draft Cooiling Tower menggunakan bahan pengisi aluminium yang ditempelkan oleh kain goni, dengan tower berbentuk balok yang terbuat dari kaca berukuran 0.1mx0.1mx1m, variasi ketinggian bahan pengisi (Z): 0.3m,0.6m,0.9m, variasi temperature air panas masuk (Twi): 50 ° C, 55 ° C, 60 ° C, variasi laju aliran massa air (L): 0.0132 kg/s, 0.0214 kg/s dan 0.0280 kg/s. Hasil penelitain menunjukkan karakteristik CT meningkat dengan meningkatnya ketinggian bahan pengisi dan temperature air panas masuk menara. Karakteristik CT akan menurun dengan meningkatnya rasio kecepatan lau aliran massa air/udara (L/G). Dari variabel yang diselidiki di dapat formula karakteristik CT. Persamaan di atas hanya berlaku pada variabel L/G 3.64-7.71, Z 0.3m-0.9m, dan Twi 50-60oC. Persamaan di atas dapat digunakan untuk memprediksi nilai karakteristik dengan besar standar deviasi kesalahan 5.152%. Sedangkan untuk performa CT diadapat nilai efektifitas ratarata 20.79%. Kata kunci: Cooling Tower, bahan pengisi, performa, efisiensi, karakteristik The aims of the experiments are to characterize of the Force Draft Cooling Tower. The experiments uses a miniature Cooling Tower Force Draft with filler material used was aluminum wire affixed with burlap cloth, with a tower made of rectangle glass with a size of 0,1mx0,1mx1m, variations in the height of filler material (Z) are: 0.3m, 0.6m, 0.9m, variation hot water inlet tower temperature (Twi): 50 ° C, 55 ° C, 60 ° C, variant of the water flow rate (L), namely; 0.0132 kg/s, 0.0214 kg/s and 0.0280 kg/s. The experimental results show that the tower characteristic increases with the increase in the packing height (Z) and hot water inlet temperature (Twi) and with the decrease in the water/air mass flux ratio (L/G). The tower characteristic is as a function of the investigated variables. The equation is valid for the ranges of the experimental variabels were L/G of 3.64-7.71, Z of 0.3-0.9m, and Twi 50-60oC. The equation can be used to predict the tower characteristic with the relative error 5,152%. The mean effectiveness of heat transfer in the tower was calculated to be 20,79%.
