Evaporative Air Conditioning
DUCTED EVAPORATIVE AIR CONDITIONING
HOW DOES AN EVAPORATIVE AIR CONDITIONING SYSTEM WORK?
The unit is placed on the roof wherein its water laden filter pads draw cool fresh air. It is then pumped into the house via ducting in the roof cavity. Stale air inside the house is replaced every 2-3 minutes, as a result, it quickly eliminates odours in the home. This system works even when windows are left open, making it ideal for large homes and those with pets and children.
WHAT ARE THE PROS AND CONS OF USING AN EVAPORATIVE AIR CONDITIONER?
- Lower cost in terms of purchase, setup, and energy consumption, compared to standard or split air conditioning systems.
- Environmentally friendly, not just from low electricity use but also because it adds moisture to air in the house naturally, it does not emit greenhouse gases into the environment.
- A constant supply of cool air is pumped throughout the home all at once with no need for zoning.
- Works even when doors and windows are open.
- Noise is barely noticeable as the unit is placed on the roof.
- Filter pads also remove dust and pollen from the air before it goes into the house
- The system requires a steady supply of water to function
- It needs consistent air supply from outside
- Regular cleaning is necessary in order to avoid accumulation of mold and mineral deposits in the pads, screens, blades, and nozzles.
- Reduced efficiency when humidity is high or when it is rainy
- Improper installation can increase risk water leaking from the ceiling outlets
- Filters do not remove all allergens and irritants from the air
HOW DOES IT WORK
Fresh air is drawn through water laden filter pads then via ducting in your roof space the cool fresh air is pumped into your home. No need to lock up your home, windows can be left open so hot air can be expelled. The air in your home is replaced every 2-3 minutes. Perfect for large homes or families with children and pets.
With the correct design and installation you can expect a 10 degrees drop in temperature even on the hottest days. When experiencing humid conditions, comfort performance can be reduced.
