Evaporative Cooling

How Evaporative Cooling Air Conditioning Works

The evaporative air conditioning unit starts by saturating its cooling pads in water. Once this cycle is complete, the fan draws air from outside, passes it through the wet filter pads to cool and filters out any pollen, dust and other pollutants. This cold, clean air is then blown through ducts and vents that are strategically placed to fill your whole home with a light, refreshing breeze. This cooling effect is the perfect antidote to stinging dry heat. You control the level of cooling with the speed settings.

Due to the way that evaporative coolers work, it serves purely as an air conditioner. While some people prefer refrigerated air conditioning that can give some heat during the winter months, the benefits of an evaporative air cooler make it an appealing choice for the Melbourne suburbs. Where a heater uses centrifugal fan and advanced technology to extract air into your home, Evaporative cooling is simple, using principles of evaporation. Being fixed to your home to create the most ideal cooling system means that it serves your home more effectively and efficiently than a portable air conditioner.

How Evaporative Cooling Air Conditioning Works

Conventional air conditioners work by recirculating air from inside the house. This means they work best with every door and window closed. Evaporative coolers, however, work by replacing the air inside your home with cooled fresh air from the outside. This means you should have some doors and windows open to keep that cool air blowing through the house. Ideally you should be replacing all the air in the home every 2 minutes. We can advise you on how many doors and windows you will need open to do this.

One of the other advantages of evaporative coolers is that they are very simple systems with not a lot in the way of moving parts. There is not a lot there that can go wrong. Really, the only active components are a fan and a pump. Evaporative air coolers can also be run in “fan only” mode when you want to purge all the stale air from your home without cooling it.

Why it's ideal for Homes in Drier Climate Areas

You may have heard that the Melbourne climate is perfect for an evaporative cooler. With ducted evaporative cooling providing a blast of fresh cool air to help you let off steam on a stinking hot day, they’re a popular choice. The reason they work so well in the Melbourne climate is because they function on an evaporative air conditioning method. This means the cooler uses moisture to cool the air that is blown by fans. A dry climate enables the moistened air to effectively cool the air. If the air were already humid then the moisture cooled air would not be as effective. With Melbourne’s air temperature and humidity levels typically between 40-50%, the climate is ideal for installing evaporative cooling as an air conditioner for your home.

An extra benefit of a ducted evaporative cooler is that the filters keep dust, pollen and other pollutants out of the home. This means that they are also the most beneficial type of cooling system for sufferers of asthma and allergens.

These Evaporative air conditioners can be installed into your home similar to the way that a refrigerated air conditioning unit is installed. This enables your whole home to be kept cool through the summer heat. Alternatively you can use a portable air conditioner such as the honeywell evaporative, placing it in the room that specifically requires cooling. The disadvantage of relying on portable air conditioners is that you will need more than one if you want to cool more than one room at a time, there is a higher level of maintenance required to keep them functioning, and they can be intrusive in your space.

Beware of evaporative cooling systems built with cheap plastic. Over time, its cooling performance deteriorates and the plastic case becomes brittle. While they may great initially, these unit are likely to cause issues in the future.

If you’re comparing through a buying guide on split system air conditioning units then a key factor is understanding the costs of running the air conditioner for your home. The evaporative air cooler is one of the most cost effective air conditioning units there is. The combined water and electricity costs of running a typical evaporative cooler in Melbourne is between 10 and 25 cents an hour. This is an incredibly affordable way to cool your home compared to air conditioning systems. Imagine being able to beat the summer heat for mere dollars a day! With electricity prices continuing to rise in Melbourne, this is a big incentive for installing evaporative cooler. Of course, with water being utilised to create the cool air your costs will be even more efficient if you have a water tank on your property to draw from.

What is Evaporative Cooling?

Evaporative Cooling is an air cooling ducted system which have been carefully engineered and designed to sit on the roof of houses to cool and filter the outside air and distribute it throughout the house using a series of ducts and vents.

Evaporative Cooling is the ideal solution for whole house ducted air conditioning in areas such as Melbourne due to the dry climate, low installation and running costs. When compared to other ducted units on the market, an evaporative cooler is the cheapest form of cooling.

How Evaporative Cooling Works?

Evaporative Cooling begins its process by saturating the filter pads with cold water. Once this initial cycle is complete, the fan then draws in the warm air from outside into the unit through the wet filter pads. This is done to lower the air temperature and filter out any pollen, dust and other pollutants before distributing it to each of the ducts.

The cool air is then blown through ducts and vents that are strategically placed around the home to provide the entire house with a light, refreshing breeze.

When it comes to Fresh Air, nothing compares to an Evaporative Cooler! Its rival Refrigerated air conditioners operates by recirculating air from inside the house which means they require doors and windows to be closed to work effectively. Evaporative coolers work by replacing the air inside your home with cooled fresh air. This means doors and windows will need to be opened for the existing air to escape as it replenishes it with new fresh cool air.
