Cooling Tower Water Conductivity Range

Coc conductivity in cooling water conductivity in makeup water.

Cooling tower water conductivity range.

Cooling towers are rated in terms of cooling tower approach and cooling tower range where the approach is the difference in temperature between the cooled water temperature and the air wet bulb twb temperature. Coc make up water quantity blowdown water quantity the last formula gives you more accurate coc if you have flow measurement facility available for makeup blowdown water in the cooling tower. Coc conductivity of cooling water conductivity of makeup water. Other cooling tower calculations.

A conductivity controller monitors the electrical conductance of the cooling water. Put for range of 0 1ppm 0 2ppm and. If the conductivity of the cooling water exceeds the front panel set point the controller activates a blowdown process. In summer the ambient air wet bulb temperature raises when compared to winter thus limiting the cooling tower efficiency.

The primary function of the tower and the method that transfers heat from the cooling tower system to the environment. During blowdown some of the highly conductive water is released and chemicals are added to the tower water. Cooling tower water ph and conductivity control application appnote 004 rev 2006 04 20 page 1 of 2. Limit the duration of the cleaning to one day or at the most two days.

The necessary precautions include. Closed circuit cooling towers with proper precautions prior to start up circulate an alkaline solution which can be used to clean condenser water systems through a closed circuit cooling tower. The range is the temperature drop across the tower example from below data. The range does not represent the cooling tower capability.

Rather the range is based on the cooling water circulation flowrate l in and the sum of the heat loads taken from the heat exchangers in the process unit q and it is not related to the size or capability of the cooling tower. Example from below data approach 85 80 5 f. On the other hand an increase in range will cause. Cooling tower efficiency range range approach x 100.
