13-13: Research on Reducing Recirculation Influence of Warm, Saturated Air

The researches show that the recirculation ratio is related to length of cooling tower row, distance between tower rows, tower structure and wind velocity and angle included between long axis of tower row and wind direction. Aim to defects of present calculated modes for cooling tower recirculation, a new formula for the warm, saturated air recirculation is presented through simulate experiments and site running test for cooling tower groups. According to the new formula, the calculated results are accordance with tested values at site. The formula can be used to optimize layout of cooling tower group.
