Quotation High Pressure fogging systems for industrial cooling.
For the additional cooling of the air during high ambient temperatures in summer, a fogging
system can be very effective.
The mechanism is simple.
With high ambient temperatures the maximum relative humidity of the air is in most cases between 50 and 60%.
If we increase the relative humidity to 95% by dissolving water in the air, the air will cool
down due to the required evaporation heat which is extracted from the air.
With a relative humidity of 60% and an air temperature of 25 C, increasing the relative
humidity to 95% will have a temperature drop of 5 degrees, resulting in an air temperature of
The achieve this we have to add 2.5 grams of water to each m3 of air.
To avoid contamination of the heat exchangers by water and to prevent damage to the motors
and drives it is necessary to make the evaporation very fast.
The have a fast evaporation, fog with droplet sizes of average 10 microns has to be produced.
This quotation is based on the above.
The nozzles are made with a check valve and an atomizing pin.
The opening of the nozzle is only 0.2 mm.
When using a pressure of 70 to 105 bars, water will be atomized.
This is an example where a
train station is cooled down
This application is a process air cooler.
Here the nozzles are located in the air inlet of the cooler before the air enters the fan.
This is less effective as the fog can be diverted by the wind.
With ACC’s the nozzles are located between the fan and the bundles, which guarantees that all the water is sprayed in the cooling air needed.
The fogging system can also be used to cool down the environment like a terrace.
The atmosphere becomes very pleasant due to the cooling.
During commissioning of the fogging system the ACC team will execute performance testing on the ACC to indicate the result of the improvements.
If the water quality requires softening, ACC Team could supply a water softener using resin to clean the water. The unit consists of two resin drums of which one is recuperating while the other is in operation.
