Pros & Cons of Evaporative Coolers

How Does An Evaporative Cooler Work?

An evaporative cooler works by cooling the air through evaporating water. The system contains a fan that draws warm outside air into the unit and cools it by passing it over water-soaked pads, which causes the water to evaporate. In other words, it is like feeling a chill when you get out of the pool on a hot summer day.

Given that an evaporative cooler merges water vaporisation with an air-moving system, it delivers more effective and efficient cooling. That’s why many homeowners in Melbourne consider a ducted evaporative cooler an ideal choice for air conditioning. You can read more about what is evaporative cooling by clicking here.

Advantages of Evaporative Cooler

Aside from delivering cool air and making the summer season tolerable for you, evaporative coolers are ideal for hot and dry areas because they add moisture and humidity to the space. You need to know that an evaporative cooler is more than capable of achieving whole-of-house cooling.

Energy Efficient

One of the leading benefits of evaporative cooling systems is that they are extremely energy efficient compared to a standard air conditioner. In truth, an evaporative cooler consumes 50 per cent to 75 per cent less electricity than an air conditioner.

Given that an evaporative cooler does not have a compressor and no refrigerant operation, it can help in significant energy savings. You can learn in detail about how much it costs to run an evaporative cooler by clicking here.

Low Installation and Maintenance Costs

For evaporative cooling Melbourne, the installation cost varies. Smaller units require very little installation, whereas a ducted evaporative cooler requires labour to install ducting and vents throughout the house.

As there are fewer working parts and simple technology, evaporative coolers don’t need much repair. The actual running and maintenance costs depend on the evaporative cooling unit’s fan speed and cooling capacity, but there’s no denying that the cost will be less than air conditioning.

Ideal Choice For Dry Climates

Evaporative cooling is a highly economical and recommended cooling method for places with dry climates. It is because the air in a dry environment has low humidity and greater potential to absorb water vapour.

Remember that an evaporative cooler uses humidification to reduce air temperature. Given that dry weather causes respiratory distress by drying out the lining of the throat and nose, skin dehydration, alteration of respiratory mucous membranes, and rhinitis, evaporative coolers improve comfort by increasing the moisture level in the air.

Filters Air Effectively

Another reason for you to consider an evaporative cooler is that it draws in warm air, filters the air by passing it through moist pads, and distributes it throughout the place. This way, the system traps dust particles, pollen, and other allergens in the air before circulating clean and fresh air.

Keep in mind that air conditioners produce dry air, which they recirculate through the filters. On the other hand, evaporative systems provide a constant supply of fresh air and a balanced humidity level if windows are open during operation.

Healthy And Eco-Friendly

An evaporative cooling system provides improved air quality and enables you to breathe fresh air without drying out the atmosphere, which is beneficial to your health.

Most importantly, it uses non-polluting, eco-friendly technology that offers numerous advantages over compressor air conditioning. From using 80% less energy than air conditioning to maintaining optimum humidity levels without refrigerants like HCFCs and CFCs, evaporating cooling is an ideal environmentally friendly cooling option.

The Disadvantages of Evaporative Cooling

Although an evaporative cooler requires minimal maintenance, there can be a buildup of salts and mineral deposits if your area has hard water. Moreover, maintenance can be a lot more inconvenient and possibly dangerous if the cooler is located on the roof.

Not Ideal For Humid Areas

Running an evaporative cooler in hot and humid weather cannot provide similar thermal comfort as air conditioning units. It is because too much humidity will hinder the air’s ability to absorb further moisture, which will inevitably affect your evaporative cooler’s performance.

The inability of an evaporative cooler in regions with higher humidity makes it a way less ideal option than an air conditioner. It would be best to have knowledge of evaporative cooling vs. air conditioning before making a decision.

Drawbacks Due To High Humidity

Although low humidity can affect your health, excessive use of an evaporative cooler result in moisture buildup, promoting the growth of mould, dust mites, and mildew in a confined space. If the humidity level rises due to overuse of an evaporative cooler, it can trigger asthma, allergic complications or a condition called hypersensitivity pneumonitis.

It is imperative for you to keep in mind that an improperly maintained evaporative cooler can easily become a breeding ground for mosquitoes and pathogens.

Conclusion

The pros of an evaporative cooler easily outweigh the cons. If you want to beat the summer heat with a highly economical method that requires minimal maintenance and is eco-friendly, evaporative cooling is the way to go.
