To study the heat and mass transfer characteristics of an evaporative cooler for cooling high-temperature working fluids, an experimental device of the evaporative cooler was built, and a corresponding test system was constructed. Then, the experimental study was carried out based on an orthogonal experimental design, and the law and extent of the influence of water flow in the tube, the spray water flow rate, the inlet water temperature in the tube, and the air flow rate on the heat dissipation, cooling efficiency, and heat and mass transfer coefficients were obtained. The correlation equations of the heat and mass transfer coefficients were obtained by fitting the orthogonal experimental data, and the validity of the correlation equations was confirmed by the verification experiment.

“…Zhou et al investigated the thermal performance of a closed wet cooling tower (CWCT) with and without packing. The result shows that the outlet temperature of CWCT with packing lowers between 0.6°C and 1.5°C and the cooling efficiency of CWCT with packing is higher than that without packing between 6.0% and 14.8%.…”

Waste heat is generally dissipated from process water to atmospheric air in cooling towers. In the present study, a novel design is used to extract more amount of heat without any additional energy input by incorporating secondary ambient air in an induced draft wet cooling tower. In addition, more fresh air is induced in the tower from the rain zone, which increases the effectiveness at any value of the water to air flow rate (L/G ratio). Moreover, tower characteristics, range, and evaporation loss were also increased due to the novel design. It is noteworthy that secondary fresh air increases effectiveness, heat rejection, and tower characteristics by 10.12%, 19.65%, and 26.11%, respectively, and decreases approach by 16.32% at 0.55 L/G ratio, 44°C inlet water temperature, 29.7°C dry bulb temperature, and 18.4°C inlet air wet bulb temperature.

In the present study, an induced draft wet cooling tower has been experimentally investigated using film, glass, and ball fills. Film fills are used only in industry where scaling is less or low-scale process water is used because of clogging of fills. Whereas, glass fills and ball fills are used for higher-scale water. The main objective of this study is to investigate the performance and compare the result of film fills with glass fills and ball fills and also predict the loss as compared to film fills when glass and ball fills were used for high-scaling water under such environmental conditions and different ratio of water to air flow and water inlet temperatures. Various performance parameters are analyzed for each of the fills and it was found that tower characteristics of film fills are 18.56% and 15.59% more than that of glass and ball fills, respectively, at water inlet temperature of 43°C and water-to-air flow ratio of 0.62. Moreover, exergy destruction was also calculated for each of the fills and it was observed that film fills destruct less exergy as compared with glass and ball fills.
