Evaporative air conditioning systems
Knowing and understanding the differences between evaporative air conditioning and refrigerated air conditioning is a good place to start in the decision making process.
An evaporative air conditioner is a device that cools the air through the evaporation of water. By drawing dry, hot air over a wetting medium that is saturated in water, the heat is absorbed and cooled and then moist air is blown through the vents.
Advantages of this system:
- Costs less to install, maintain and run because they’re less mechanically complex than a refrigerated air conditioner.
- More eco-friendly (producing less emissions and using less energy) than a refrigerated air conditioner.
- Uses fresh air from the outside, instead of constantly recycling stale air.
- Good for children, asthma sufferers and the elderly as the cool air still contains moisture.
- Can be portable or fixed.
Disadvantages of this system:
- Evaporative air conditioners tend not to run well in high humidity areas. While an evaporative air conditioner might work well in Canberra, in Sydney it may be a very different story. If you are new to an area, make sure you do some research about the summer heat conditions and humidity levels before opting for an evaporative air conditioner.
- Reduced security when windows and doors are open (although security vents can be installed).
- Rooms need to be well ventilated with good air flow to allow the hot air to escape otherwise it is possible for condensation to form inside the house as a result of the elevated indoor humidity.
- Can require a substantial amount of water to run.
