The benefits of evaporative air conditioning

The benefits of evaporative air conditioning are plenty, there’s never been a better time to invest in an evaporative air conditioner which is simple to maintain and operate and offers superior product performance. With energy prices escalating and Australian summers typically involving heat waves, evaporative air conditioning offers a significant and increasing edge on reverse cycle, when it comes to energy efficiency, healthier air flow, performance and lifestyle.

Ducted evaporative cooling is one of the oldest and most beneficial forms of keeping cool. Evaporative air conditioners also have many key advantages vs. refrigerated air conditioners that keep more money in your pocket and less pollutants in the air.

As the name suggests, an evaporative air conditioner uses evaporation to help cool the air. Based on the principles of evaporation, hot and dry outside air is pumped through water-soaked cooling pads using an evaporative cooling fan. As the air is pushed through the cooling pads, the water evaporates and the heat in the air is absorbed, which lowers the air temperature. A fan then pushes the cool air throughout a house via a network of ducts.

It is important to remember that cooled air inside a home is not recirculated, so a door or window is left open for this air to escape, providing a home with a complete change in air at least every two minutes.

But what are the benefits of evaporative air conditioning?

 

Evaporative Air Conditioning Benefit – Evaporative cooler efficiency

At a time when Australians are faced with high energy costs, there is plenty of debate when it comes to evaporative vs refrigerated air conditioning running costs. The reality is that one of the most significant benefits of evaporative air conditioning is that running costs are far lower vs. refrigerated options.

In fact, a ducted whole-house reverse cycle air conditioning system is accepted to be the biggest money pit when it comes to home cooling, costing between $2.45 – $3.45 * per hour to run. Faced with such high running costs, it is staggering to think that nearly half of all Australian households (49%) ** still opt for reverse cycle air conditioning as their main form of cooling and heating.

However, modern and innovative evaporative cooling products see savvy consumers save up to 90% on energy bills when compared to a reverse cycle air conditioner.***

Better indoor air quality

When the weather heats up there is nothing worse than being shut away inside breathing stale air for hours on end. Fresh air is a major benefit of evaporative air conditioning, supplying 100% fresh, cool, outside air, all while delivering superior energy efficiency compared to a refrigerated equivalent. As the fan within an evaporative air conditioner draws outside air though the cooling pads, not only is the air chilled but it is also filtered from impurities and pollens – a bonus for allergy sufferers.

Evaporative air conditioners are eco-friendly

Refrigerated cooling can not only cause the air to become dry inside a home, but it also uses chemicals which can damage the environment. In comparison, evaporate cooling is based completely on natural processes which cools air using water, with no chemicals involved.

Compared to refrigerated air conditioning, the air released from evaporative coolers is never re-circulated, and is constantly replaced with fresh air – meaning your eyes and throat won’t become irritated and people with respiratory and health issues can enjoy their time indoors.

Better for the environment and better for you

Opting for evaporative air conditioning means that you will not only help the environment but you will also experience natural, cool, fresh filtered air. Evaporative air conditioners use far less electricity compared to refrigerated systems therefore, less fossil fuels such as coal and natural gas are consumed in the production of electricity. Evaporative air conditioning systems contain no harmful synthetic refrigerants. Compare this to refrigerated systems which may use potent greenhouse gases like hydro fluorocarbons or chlorofluorocarbons, which deplete the ozone layer. The power consumption of just one ducted reverse cycle air conditioner can result in up to 1.5 tonnes of harmful CO2 being pumped into the atmosphere each year. A Breezair evaporative air conditioner is so efficient it produces less than one tenth of this volume. ^

Easy maintenance

Regular service by a qualified technician from time to time will ensure the unit continues to run at its peak efficiency and maintain low evaporative running costs. Organising an evaporative cooling service is fast, simple and easy to arrange through a network of dealers and service agents throughout Australia.

Water usage

Evaporative air conditioners use a small amount of water, in many instances using almost 98% less water than a shower over a year. A Breezair evaporative air conditioner for example, uses around 15 litres of water a day averaged over a year. This is far less than a front loading washing machine which uses around 60 litres of water for one wash, or a top loading washing machine that uses on average 150 litres of water for one wash. ****

Add moisture to the air

Evaporative air conditioning can also help to slightly increase the amount of moisture in the air. This is especially beneficial for people living in dryer climates who can find it difficult to breathe or experience dry and cracked skin when using refrigerated options.

Flexible security

One of the great advantages of an evaporative air conditioner is that doors and windows can be left open – which is great news for people with children and pets who like to frequently come in and out throughout the day. That convenience doesn’t have to compromise your home security however, because Security Relief Vents can be fitted into a ceiling – which means you sleep easy with all your doors and windows locked while the system runs overnight.

Whisper quiet operation

In the dead of night there’s nothing more annoying than a noisy hum of an air conditioner. Seeley International’s evaporative air conditioners have a reputation for being exceptionally quiet, so you won’t hear a thing as you sleep, particularly the Breezair which is renowned for being whisper quiet.

How is an evaporative air conditioner installed?

Evaporative air conditioner installation is completed by a qualified trade person who can connect and install the roof top unit, ducting, water, power and controller. Contacting a reputable dealer is the best way to organise air conditioning installation to ensure you receive a comprehensive warranty, after sales service and peace of mind. Dealers can also assist in accurately estimating the unit capacity best suited for your lifestyle and home size. You can find one of our dealers by clicking here: Find a Dealer. 

Spare Parts and Service

Evaporative air conditioner parts are readily available and can be bought direct from the manufacturer, through a dealer or distributor with installation generally offered in conjunction with the part being purchased. Evaporative cooling pads are popular replacement parts that are simple to remove and replace by a qualified trade person and their replacement helps optimise running efficiency and effectiveness.
