COMPARING THE NOISE CHARACTERISTICS OF DIFFERENT TYPES OF COOLING TOWERS

Abstract

Comparing the noise characteristics of natural draft counterflow cooling towers during their operation with dry cooling
towers at the same cooling capacity carried out. The difference in the reasons for the noise generation of natural draft counterflow cooling towers in comparison with dry cooling towers showed. A condition obtained for the pressure of axial fans for octave bands and for the sound level in dBA, when dry cooling towers emit sound energy more than natural draft cooling tower. It shows that dry cooling towers are noisier than natural draft cooling towers for the same cooling capacity.
