Resumé

This paper presents the results of energy, exergy and exergoeconomic analysis for a forced draft cooling tower. The work was done using field data from an operating system spanning ten (10) years. The process was modelled mathematically and computer simulations were made using the MS Excel environment, specifically on the dependence of both the energetic efficiency on the inlet water temperature and the second law efficiency on the inlet water temperature, ambient temperature and relative humidity was investigated, and the cost associated with the exergy destroyed, the average cost per unit exergy, ratio of mass flow rates of water and air and the exergoeconomic factor for the cooling tower were simulated. The results from the analysis compare formally with those in the literature; this study demonstrates that exergoeconomic analysis can provide extra vital information than the energy and exergy analysis alone. Keywords: Cooling tower, exergy analysis, second-law efficiency, exergoeconomic analysis
