How an Evaporative Cooler Works?

Look! It useswater not CFCs

Hot air is drawnthrough pads andheat evaporated off

Cool filtered aircontinually flows,without recirculation

As warm air passes over wet filter pads water naturally evaporates into the air.The air is cooled as it gives up the heat required to evaporate the water.

Principle of Evaporative Cooling

Cooling is provide by Evaporative heat

exchange which takes advantage of the

principles of the latent heat of evaporation

where tremendous heat is exchanged

when water evaporates. It makes use of

the free latent energy in the atmosphere.

Energy Saving

No harmful refrigerants are used just the

natural process of evaporation to provide

the cooling.

Unlike air conditioning evaporative

cooling uses clean fresh air, allowing

odours and bacteria to be expelled

naturally through the ventilation system

without being re-circulated.

Balanced Ventilation System

When Evaporative cooling is used as part

of a balanced ventilation system to cool a

building, this allows the exterior air to be

used most of the time, making the most

use of free cooling when available,

therefore minimising costs and using

natural resources.

On the hottest day in the Summer up to

22°C of cooling can be achieved through

this process, thus providing excellent

comfort cooling for most building

requirements.

Mechanics of Unit

Water is brought into the cooler from the

mains water supply and is pumped up to

the top of the unit using a circulation

pump. The water is then dispersed over

the Cooling pads using a water

distribution system which allows the

water to flow continually over the pad.

Cooling pads

The pads become saturated, air is drawn

through the pads and the water

evaporates causing the air to cool. The

cool air is then ducted round the building

to provide cooling by means of an axial

fan. hot air in cool air out - evaporative

cooling from NE Cooler.

quality of cooled air, alleviatesthe workspace temperature,increasing worker efficiency

As ambient temperature rises, energy consumption increases, efficiency decreases

Can guarantee a fixed temperature

Can only operate well in a closed environment

Re-circulates approximately 80 ¨C 85% internal stale air

Dehydrates the atmosphere within the working environment

Does not filter any air, leaves dust, minerals and bacteria in the air-stream

As ambient temperature rises, energy consumption remains constant, efficiency increases

Temperature dependant upon ambient conditions

Needs to operate with ventilation, open environment

Operates with 100% fresh air, no re-circulation

Slightly increases humidity level in the working environment

Some filtration of air, removes dust, minerals and bacteria from the air-stream

NE Air-cooler Uses Various Type of Applications

NE Evaporative Coolers can reduce the electricity usage and carbon impact of server room and data centre cooling systems by over 90%

Computer Room Air Conditioners (CRACs) are use arefrigeration system to cool air and pass it to the void under theraised floor.

NE Air-Cooler takes external air and passes it to the void underthe raised floor. Below 18ºC ambient air is taken and mixedwith air re-circulated from the hot aisle. Above 21ºC theNE Air-Cooler uses evaporative cooling to provide air which neverexceeds 22ºC.
