Evap Cooling in Orange

Evaporative systems work best in dry conditions, as the process relies on water evaporation to cool the air. When humidity is high, their efficiency drops because the air is already saturated with moisture. They will still provide airflow, but the cooling effect won’t be as strong. For homes in regions with occasional humidity, many households use evap cooling alongside ceiling fans or other systems as a backup.

Water is essential for evap cooling, but usage is usually modest compared to the electricity saved against refrigerated systems. On average, a household unit might use between 15–25 litres per hour on hot days. This cost is often balanced out by the much lower running costs in electricity. Newer systems also include water management features that reduce wastage and improve efficiency.

Yes, open windows or doors are actually recommended with evap cooling. These systems work by drawing in outside air, passing it through damp pads, and pushing it indoors. Fresh air needs an escape route, so keeping some openings ensures circulation and prevents humidity build-up. Unlike refrigerated systems, this design helps keep the home fresh rather than sealed.
