To this aim, air at environment temperature is blown in through the bottom of the tower by a fan. Meanwhile, the system sprays the hot water in the upper side of the tower, this water is cooled until environment temperature is achieved, then reheated and the process begins again.
The water tank is equipped with a calibrated feeder that shows precisely how much water has evaporaded during the process.
The unit is supplied with a computer that has the software already installed. This software can adjust the water and air flow through two PID controllers, while the screen shows the temperature and moisture degree in certain strategic points and at the push of a buttom all the relevant data is stored in a table.
The software displays the data for any given cooling tower, along with a diagram flow, to make the learning of the fenomenon easier.
Additionally, the software incorporates an automated calibration system.
