You must have been asked this question several times over the years and with the ever-increasing efficiency of forced air conditioning units, you could still come up with various reasons why evaporation cooling has been still a beneficial and useful cooling option, especially in Melbourne.
Lower installation cost
Foremost would be the initial installation cost. Split system and rooftop air conditioning units have been subject to a government-mandated efficiency, which has forced several air conditioning manufacturers to advance to highly exorbitant refrigerants, cabinet sizes and components. This enhances the cost of air conditioning units to another level. Meanwhile, evaporative cooling unit costs have stayed significantly low. A usual rooftop air conditioner could cost more than the evaporative cooling system to be installed on a 2000 square foot house. However, an evaporative cooler for the same size house could be installed for less. It would be even less, if you are able to do it on your own. Evaporative cooling has been the cheapest form of ducted cooling to be installed in your home. As a result, you would be cooling your home with minimum investment.
Secondly, evaporative cooling has been believed to be green technology. Evaporative coolers would use up to approximately 90% less electricity than other available air conditioning units. They also do not make use of chemical refrigerants, which have been associated with the depletion of upper atmosphere ozone layer. Moreover, coolers make use of water and air only.
Addition of moisture
Yet another great benefit of evaporative cooling, which has been subject to preference, has been the addition of moisture to the conditioned air. The moist air could feel very comfortable, especially when your home is in dry climates. The water based cooling process would mean evaporative cooling that does not dry the air out. This has been great for people suffering from allergies, asthma or hay fever. On the other hand, air conditioning would actually remove moisture in the air, as it would cool it, leaving the conditioned air highly dry.
Save your energy bills
The lower running cost of the evaporative cooling system enables you to reduce your energy bills significantly. You would be able to save your precious money along with doing the environment a world of good.
No harmful gases
There have been no harmful gases used in the evaporating coolers, as the natural water based cooling procedure does not require additional gases.
What makes evaporating coolers cost effective?
Evaporating systems have been amongst the cheapest ducted cooling systems to be installed in your home. It would not be wrong to suggest that they have been mostly 50% much cheaper than refrigerated cooling. However, it would be depending on the model. In addition, it would be three times cheaper to run in comparison to the refrigerated cooling system.
A usual evaporative cooling melbourne system has been ideal for an area of 150 square metres. It has a running cost of around 12 cents per hour. This has been considerably cheaper than both split system air conditioning and ducted refrigerated air conditioning.
