The Lowest Dropable Temperature Value Of A Closed Cooling Tower

We can say with certainty that the temperature cannot drop indefinitely, the lowest can only drop to the wet bulb temperature +3 degrees, which is explained in accordance with normal conditions.

So what is the wet bulb temperature?

Answer: The wet bulb temperature is the lowest temperature that water can reach through evaporation in a natural environment. This temperature can be the limit temperature of the cooling tower.

But under normal circumstances, we cannot completely drop to this temperature. The range we can control is the wet bulb temperature plus 3 degrees as the lowest temperature for normal cooling. After determining this temperature value, you must pay attention to the operation of the cooling tower, and it cannot exceed this range, otherwise even its normal use will be affected.

Wet bulbs in different regions are different, so in the selection of cooling towers in different regions, wet bulb temperature is a very important selection factor. According to the principle of cooling towers, we want to reduce the temperature of the wet bulb, we must To make the cooling tower infinitely larger, it can only be 99.9999% close to the wet bulb temperature. Of course, this is unrealistic in the model selection.
