There is a loss of water in the cooling towers during the day when temperatures are high. Refilling the water system is not possible. Water cools a heat exchanger. There are three pumps to circulate the water and two cooling towers. The cooling system keeps the temperature at the heat exchanger output constant.I am interested if the shutting down a pump and increasing the fan speed will reduce water losses?Or maybe to turn on one more pump and reduce fan speed?Currently working with one or two pumps, and two cooling towers.
jtodic,
In a wet cooling tower system, the cooling capability is limited by local wet bulb temperature and approach. Then, if your existing cooling tower had been designed and optimized properly the only way to compensate the water loss is providing make-up water and system variables (fan speed, circulation velocity,...) changes nothing to do with improvement in system's cooling capacity...

Hi jtodic,
What you call loss is normal evaporation unless you got loss through the louvers (drift) or an excess of blowdown .
Refer to the docs attached.
good luck.

The loss of water is mainly due to e a portion phenomenon in the coolIng tower.
The cooling power of the tower is directly linked to this evaporation.
