The purpose of the ongoing experimental studies is to determine the hydraulic resistance of the cooling tower sprinkler block, which consists of inclined-corrugated contact elements. The paper presents an original method for cooling circulating water in cooling towers, which allows to significantly reduce the use of chemicals, not inferior in efficiency to analogues. An experimental setup was developed and created, on which hydraulic and heat exchange studies of the inclined-corrugated element of the sprinkler block were carried out. The experiments were carried out on an air-water system. During the experiment, it was revealed that the hydraulic resistance of inclined-corrugated elements is higher than that of jet-film ones. Despite this, the hydraulic resistance of inclined corrugated contact elements can be reduced by increasing the free cross section for the passage of gas. Thus, it is recommended to increase the diameter of the holes and their number. The temperature regimes in which this block of the attachments and its hydraulic resistance operate are determined, as well as studies show the high efficiency of the developed attachments, which has a low hydraulic resistance, a small percentage of liquid entrainment from the apparatus. In addition, the use of the developed three-furnace scheme for cooling circulating water will significantly reduce the amount of chemical reagents used to containment the development of bacterial deposits.
