Industrial and commercial evaporative cooling systems have several benefits.
Evaporative cooling system diagram.
The evaporative cooling system is used to raise both power output and efficiency of gas turbines.
The cooling provided by water evaporation is the most natural cooling system.
These systems use only a fraction of the energy of typical compressor based cooling systems.
Factory cooling ventilation system experts cool your workspace using evaporative cooling systems hvls fans and more the leader in factory cooling industrial ventilation 095 550 0838.
Compare to evaporative cooling some of the disadvantages of using this type of air cooling systems include a higher cost to operate more energy use routine cleaning and maintenance.
These fog systems can be designed and operated to.
As the water that is in contact with hot air evaporates it absorbes the heat of the air and reduces its temperature.
The parts of an evaporative cooler are all designed to facilitate efficient evaporation of water and circulation of the cooled air.
The process is indicated in the mollier diagram below.
Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate.
The power output and efficiency rating of gas turbines are usually based on iso conditions inlet air temperature 288 k and 65 relative humidity.
Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles.
The basis of any evaporative cooling system is the evapora tion of water into an airstream.
If a q tonnes of refrigeration is the cooling load in the cabin then the air required for the refrigeration purpose power.
High pressure fog systems are also used to cool green houses.
If the inlet air is hotter and drier than iso conditions the.
In the evaporative cooling mode the air is cooled by contacting the.
An evaporative cooler also swamp cooler swamp box desert cooler and wet air cooler is a device that cools air through the evaporation of water.
The evaporative cooling process occurs whenever hot air is in contact with water.
The t s diagram for simple air cycle evaporative cooling system is shown below.
As water evaporates it effectively consumes heat from the surrounding air it is the same principle by which an air fan cools you as it evaporates perspiration from your skin.
In addition you ll find that it emits higher levels of carbon dioxide co 2.
The direct evaporative cooling process in a mollier diagram air with dry bulb temperature 30 o c and relative moisture 60 state a is cooled down state b by evaporating water.
Evaporative coolers often known as swamp coolers work by extremely simple physics.
Highly efficient evaporative cooling systems can reduce energy use by 70 the actual savings will vary with the type of evaporative system and climate.
