This study shows how by reducing the cooling water circulation rate, improves the
efficiency ofthe operations in the cooling tower system. This is done without modifying
the internals of the current cooling towers such as the fills, water treatment programme
and air flow rate. This study is applicable for all existing plants with the cooling tower
system. This study shows the redistribution ofcooling water in the cooling tower water
network. This study with detail calculations are tested for chillers, distillation
condensers and air conditioners. The cooling tower performance curve is used as the
tool for this analysis. The benefits of this study are colder cooling water temperature,
reduce the compression work of the refrigeration cycle by 3.0 % for every 0.6 C
reduction inthe cooling water temperature, reduce the cooling tower water consumption,
reduce the cooling tower water treatment chemical consumption, reduce the cooling
water circulation pump power consumption, and increase the heat transfer of the
distillation condensers (increase production)
