Things worth knowing about cooling towers and evaporation plants

As is the case in any sector, certain specialist terms exist in the field of recooling technology, stemming for the most part from physics.
Here we provide an overview of the most important terms and definitions.

There are 4 names in this directory beginning with the letter C.
Cold water temperature
Cold water temperature tW2 [°C] is the average temperature of the cooled water in the outlet structure, not influenced by the make-up water.
Cooling capacity Q
Cooling capacity Q [MJ/s, MW, KW ] Energy flow discharged from the water into the air (heat quantity). Every cooling tower operated within the circulation system, irrespective of size, discharges the total quantity of heat with which it is charged.
Cooling range
Cooling range Z = tW1-tW2 [K] is the difference between the warm water temperature tW1 and the cold water temperature tW2. The cooling range is not determined by the cooling tower, but rather by the heat exchanger assigned to it. The cooling range is dependent on the heat quantity and the mass water flow. Comment: small z = large cooling tower; large z = small cooling tower
Cooling tower
The cooling term is used for the cooling of heated water. Inside of the cooling tower the water is evenly dispersed over the cooling installations, and is brought into direct contact with the air. The majority of the cooling takes place by means of evaporation, with a smaller proportion resulting from convective heat transfer.
