Summary

Combined transfer of heat and mass on a wet surface takes place in cooling towers. The heat of evaporation cools the cooling water and heats the air in counterflow. The quality of the inlet air and its wet bulb temperature as well as the approach defines the proper operation of the cooling tower. The required cooling surface, the volume of the spray chamber and the air speed are important variables in the calculation of the necessary cooling capacity. Cooling towers are able to cool down process water in an energy efficient way by means of a suitable condition of fresh air and the required in- and outlet temperature of water. Worldwide, manufacturers are becoming specialized in the construction of energy saving water-cooling systems.
