The process of evaporation is simple enough to understand. However, what you may not realize is that as the water changes state from liquid to gas, it cools the air around it. In this article you will learn more about applications for evaporative cooling. Therefore, you might happen to feel a temperature drop as you approach a large dam or lake late in the afternoon. This principle has now been harnessed by technology to bring cool air into your home. An evaporative cooling unit, or swamp cooler, will be able to be substituted for a traditional air-con unit in your home and you will enjoy a large reduction in your cooling costs over the next summer season.

How an evaporative cooler works

An evaporative cooling unit uses a fan to pull in air from outside into the cooler. The air then passes through a set of porous material pads that are damped with water. The water is consistently pumped from the reservoir in the cooler housing, up over the pads, keeping them damp at all times.

The air then passes through these pads where it is evaporated, cooled and then pushed out into the living space by the fan. The outgoing air is moist and needs to be exhausted from the room by opening a door or a window. This allows the warm, moist air to escape the room and the cool air to circulate inside.

Make sure that you match the correct size cooler to your room. If the unit is too powerful, it may end up causing the surfaces in your room to be wet, which would not be good for electrical equipment. If the cooler is too small, then it will not have enough power to cool the room down sufficiently. For advice on what cooler to use for your room size, drop us an email, or call into our head office and one of our consultants will be happy to help you select the right cooling solution for you.

Drawbacks of evaporative coolers

Evaporative coolers are a great, cheap means of providing your home or office with cool air in the long summer months. However, they do not suit every living environment. Evaporative cooling units are best used in dry, hot locations where they are able to operate with maximum efficiency. They will not be effective in humid locations that are near sea-level, or large bodies of water, strangely, even though their name may imply it, swap coolers would not work very well in a swamp at all.

10 uses for evaporative coolers in industry

Evaporative cooling has become a cooling solution to take seriously. With the improvement in design and technology coming a long way in recent decades, evaporative cooling is now a serious competitor to traditional air-conditioning in many residential and commercial applications.

When it comes to the commercial and corporate use of evaporative coolers, the benefits are tremendous. Traditional air-con systems for large retail areas such as shopping malls require an enormous amount of energy to operate. Changing this system to an evaporative cooling unit can save you up to 70% of your average cooling bill, for large shopping centers, this means hundreds of thousands in savings every year.

Along with the cost savings benefits, your company or organization can benefit from the reduced emissions produced by evaporative cooling systems. This reduction in carbon output makes for an eco-friendly environmental operation that can be noted for energy based rebates with your energy supplier. You can view the full range of GMC Aircon evaporative coolers in our online shop where you can shop now, of course if you have any questions at all then please don’t hesitate to contact us and one of the team will be more than happy to help.

The benefits to large commercial operations also extend past just the energy savings. They are incredibly easy to install and maintain, with few working parts and units now available that are centrally controlled with electronic climate controls linked to thermostats and regulators that increase the efficiency of the systems even further. The maintenance savings, as opposed to traditional air-con, is quite dramatic as well.

Heavy industry and other commercial applications rely on air-cooling systems to allow their working conditions to be tolerable. Previously evaporative cooling had a drawback in the fact that it required the spent warm aide to be exhausted, otherwise, the room would become damp from the moisture in the air brought in by the cooler.

Technology has since marched on and with the development of ducting systems for these operations the evaporative cooler no longer gives these problems to its users. Let’s take a look at 10 industrial and commercial applications for evaporative coolers;

  1. Commercial kitchens
  2. Large factories
  3. Large warehouses
  4. Office buildings
  5. Retail centres
  6. Indoor sports facilities
  7. Large outdoor marques
  8. Greenhouses
  9. Restaurants and guest houses
  10. Mining operations

All of the above-mentioned applications majorly use air-conditioning for their cooling needs. If they were to all convert to evaporative cooling solutions, this would make for a huge reduction in national energy consumption and the global reach would be absolutely staggering. It has become every corporates responsibility to reduce their carbon footprint and using an evaporative cooling unit is a way of offsetting the business unit’s consumption.

This is a self-fulfilling conclusion; Evaporative cooling technology has developed to a point where it is the clear market solution that offers increased efficiency, massive cost savings compared with traditional air-cons and lower carbon emissions. They are simply the cooling solution that industry should adopt and make the new benchmark standard.
