CSIRO’s Opinion On Ceiling Fans
Ceiling fans are a very economical way to help cool a home. This air blowing downward can reduce the temperature next to you by 2°C to 3°C. The following tips will help you get the most from a ceiling fan:
- You can use a ceiling fan with a reversible switch to distribute warmth through a room by running it in the opposite direction. This moves air upwards and displaces hot air that accumulates near the ceiling so it circulates through the whole room.
- If you have timers on your air conditioner and ceiling fan, try setting them to run cooperatively. For example, running the air conditioner for a while to cool the room, then turning it off and switching on the fan to circulate the conditioned air. This can substantially reduce your air conditioner use and can be particularly useful for bedrooms on hot summer nights.
- When buying fans, ask how much power the motor uses. An inefficient fan motor can undo much of the greenhouse gas savings. An efficient fan producing 140 cubic meters of airflow a minute typically has a power of 75 watts – 1.87m3 / watt.
Spinifex Fan’s energy performance is between 2.26 – 2.70 m3 / watt, well above the CSIRO benchmark. See the Spinifex Fans technical specifications data sheet for further information. The Spinifex Resource Library also contains a number of useful articles on ceiling fan performance and ceiling fan selection that we recommend reviewing.
