Studies on determining thermotechnical characteristics of cooling tower filler
Summary
The results of the experimental studies on determining the process efficiency of redesigned filler in a cooling tower model are presented. The experts of «AIR» CJSC have designed and assembled an experimental cooling tower model for testing the filler and the water catcher. The instrumentation system for measuring temperature at the inlet and outlet, air temperature and humidity, air and cooling water flow rate is described. In the course of aerodynamic tests the coefficients of the filler and water catcher hydraulic resistance were determined; in the course of thermotechnical studies the cooling ability coefficient was determined. The results of the experimental studies of the filler consisting of two blocks with 0.68 m gap between them showed that the filler is of sprinkling-film type and has cooling capacity А = 0,44 l/m. The tests carried out in full-scale blocks of the filler and water catcher corresponded to the actual conditions of the cooling tower operation.
