Evaporative Cooling System Diagram

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 cooling system diagram.

In the evaporative cooling mode the air is cooled by contacting the. Evaporative coolers often known as swamp coolers work by extremely simple physics. The t s diagram for simple air cycle evaporative cooling system is shown below. Industrial and commercial evaporative cooling systems have several benefits.

If the inlet air is hotter and drier than iso conditions the. 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. Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles. 7 5 3 evaporative cooling system.

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 power output and efficiency rating of gas turbines are usually based on iso conditions inlet air temperature 288 k and 65 relative humidity. 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. The process is indicated in the mollier diagram below.

The parts of an evaporative cooler are all designed to facilitate efficient evaporation of water and circulation of the cooled air. The evaporative cooling process occurs whenever hot air is in contact with water. High pressure fog systems are also used to cool green houses. These systems use only a fraction of the energy of typical compressor based cooling systems.

These fog systems can be designed and operated to. The evaporative cooling system is used to raise both power output and efficiency of gas turbines. The most common way of accomplishing evaporative cooling in a greenhouse is with a fan and pad system figure 1. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate.

Highly efficient evaporative cooling systems can reduce energy use by 70 the actual savings will vary with the type of evaporative system and climate. The cooling provided by water evaporation is the most natural cooling system. 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 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.
