Design, Fabrication and Determination of Performance of a Cooling Tower
The essence of this research is to study the basic principles and characteristics of evaporative water cooling tower system and to investigate cooling tower performance and key design factors. Also, to make available the experimental set up for the demonstration of the cooling process using a cooling tower. The performance or effectiveness of the cooler tower fabricated is about 54.84%, thus, it can be comfortably deduced that the cooling tower so fabricated is within the desired effectiveness value, as determined by literature which the recommended industrial value should not be less than 40%. As determined by the experiments carried out, it has been established that for cooling towers, the outlet temperature can never be less that the ambient temperature, it has also verified that the best temperature difference cooling towers can give is a temperature difference between the outlet temperature and the ambient temperature. The material of choice for the fabrication which is Perspex was chosen because of its environmentally friendly nature, light weight and financially inexpensive, not disregarding its transparent nature which gives the researcher the opportunity to appreciate the process as it occurs in the system. The efficiency of the cooling tower fabricated relies on the accurate and reliable outdoor wet bulb temperature instruments. Shortcomings can result in cooling tower overuse, leading not only to increased water and energy usage but also reduced lifetime of fans and pumps.
