Save water by using adiabatic cooling towers
Save water by using adiabatic cooling towers
An adiabatic cooling tower saves more than 95% of water compared to a traditional cooling tower with closed cooling circuit.
Cooling tower with closed cooling circuit
A cooling tower with closed cooling circuit is usually used if the water to be cooled may not come into contact with the ambient air.
With a cooling tower with closed cooling circuit no contamination can arrive in your water to be cooled and none of your water to be cooled will evaporate.
Comparison made between traditional cooling tower with tubes and adiabatic cooler.
Calculation of the traditional cooling tower
Cooling tower for cooling 151m³ water/ethylene glycol 30% mixture.
Water/glycol mixture to cool from 32 to 27°C at an ambient air wet bulb temperature of 21°C
Discharged cooling capacity 800kW.
Calculation made for an installation at full load, 24 hours a day and 7 days a week operation.
With a traditional closed evaporative cooling tower we have evaporation water and discharge water, which together account for water consumption.
Evaporation with traditional closed evaporative cooling tower: 9610 m³/year.
With a traditional closed evaporative cooling tower, besides the evaporation water account must also be taken of the discharged water.
For this comparison we have made the calculation with a concentration of 4.
Discharge with concentration of 4: 3203 m³/year.
Consommation d’eau annuelle totale pour une tour de refroidissement traditionnelle fermée à évaporation : 12813 m³
Calculation of the adiabatic cooling tower
With an adiabatic cooling tower or adiabatic cooler there is only evaporation, and that above a dry temperature known beforehand. In this example from an ambient temperature of 21 °C and higher.
If the outside temperature is lower than 21 °C, this type of adiabatic cooler will have no water consumption and the heat will be discharged dry.
Total water consumption per year for an adiabatic cooler: 474 m³.
