“…So, the combination of operating principles of dry and wet CTs makes it possible to reduce the vapor plume and save high heat power [6,7]. In addition, to improve the heat power of the wet/dry cooling tower, a finning of the outer surface of the exchanger pipes was implemented, which increases the heat exchange surface [8,9]. Furthermore, finned exchanger pipes allow the heat-transfer resistance to be equalized without significant increases in pressure drop [10,11].…”

A hybrid system for recirculated water cooling of industrial enterprises is proposed. The major feature of the cooling system is a wet/dry cooling tower with an inner pipe exchanger. To enhance the heat transfer process, the outer surface of the heat exchanger pipe has fins. Design and function of the experimental setup are described. The goal of this work is to evaluate experimentally the heat power of the wet and pipe sections of the cooling tower. Results were presented as dependencies of the heat power in the wet/dry cooling tower on the mean gas velocity (from 0.89 to 3.20 m/s) and the ratio of the weight flow rates of the gas/liquid phases at various irrigation rates (13.7-35.6 m3/(m2.h)).
