Experimental Study of Hydraulic and Heat and Mass Transfer Parameters of Inclined-corrugated Contact Elements of Cooling Tower Sprinkler
https://doi.org/10.18412/1816-0395-2020-1-4-8
Abstract
The scheme of cooling tower operation with non-contact evaporative cooling technology is presented. A new design of the cooling tower sprinkler unit consisting of inclined-corrugated contact devices has been developed. The structure contains a system of pipes through which the flow of water moves without contacting the air. Studies have been carried out to determine the hydraulic resistance of inclined-corrugated contact elements with changes in air velocity and irrigation density. Thermal efficiency in a cooling tower with inclined-corrugated contact elements can reach 33 %.
