Evaporative Cooling System Diagram

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.

Evaporative cooling system diagram.

If the inlet air is hotter and drier than iso conditions the. High pressure fog systems are also used to cool green houses. 7 5 3 evaporative cooling system. In the evaporative cooling mode the air is cooled by contacting the.

The evaporative cooling process occurs whenever hot air is in contact with water. 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. 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. Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles.

These fog systems can be designed and operated to. The t s diagram for simple air cycle evaporative cooling system is shown below. The parts of an evaporative cooler are all designed to facilitate efficient evaporation of water and circulation of the cooled air. The various processes are same as in the simple air cooling system except that the cooling process in the evaporator is shown by 4 4.

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. The evaporative cooling system is used to raise both power output and efficiency of gas turbines. 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. 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. In addition you ll find that it emits higher levels of carbon dioxide co 2. The cooling provided by water evaporation is the most natural cooling system.

As the water that is in contact with hot air evaporates it absorbes the heat of the air and reduces its temperature. Evaporative coolers often known as swamp coolers work by extremely simple physics. Industrial and commercial evaporative cooling systems have several benefits. The most common way of accomplishing evaporative cooling in a greenhouse is with a fan and pad system figure 1.

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.
