An evaluation of the cooling capacity of a hybrid cooling tower with a finned tubular radiator

Cooling towers are an important component of the recycling water supply systems of industrial enterprises. When comparing different cooling methods, evaporative is the most effective. However, because of their shortcomings, studies have been conducted to optimize them. Hybrid cooling systems are the most practical and effective ways to prevent the formation of large steam flares, requiring the addition of an excessive amount of water. Hybrid cooling towers also provide additional advantages over other conventional cooling towers in terms of their efficiency and savings of chemicals during maintenance. The authors proposed a hybrid cooling tower design with a finned tubular radiator. To predict heat and mass transfer in the tower, they assembled an experimental installation, determined the thermal efficiency in the evaporative part of the cooling tower, and analyzed the cooling capacity of inclined-corrugated contact elements with a finned tubular radiator. With an increase in the irrigation density of the coolant, there is a slight decrease in thermal efficiency because of the resistance provided to the air flow in the corrugated elements. Studies have shown that the highest cooling capacity of inclined-corrugated contact elements is observed at low irrigation mass densities and can reach 35 % without significant drip entrainment.
