The headline “Fan as an air conditioner: The 50-cent trick that helps beat the heat” usually refers to simple ways of making a fan feel cooler, but a fan does not actually cool the air like an air conditioner.
A few low-cost tricks can improve comfort:
1. Place a bowl of ice or frozen bottles in front of the fan
- The fan blows air over the colder surface, which can make the airflow feel cooler.
- It works best in a small room and for short periods.
- It won’t lower the room temperature significantly because the ice eventually melts and releases heat back into the room.
2. Improve airflow direction
- Put a fan near an open window during cooler evening hours to pull fresh air in or push hot air out.
- In hot weather, avoid blowing hot outdoor air inside during the hottest part of the day.
3. Use the fan to cool yourself, not the whole room
Fans mainly work by increasing evaporation of sweat from your skin, which makes you feel cooler.
Other cheap ways to reduce heat:
- Close curtains or blinds during direct sunlight.
- Use light-coloured window coverings.
- Ventilate at night when outdoor temperatures drop.
- Avoid running heat-producing appliances during peak heat.
So the “50-cent trick” can make a fan feel more refreshing, but it does not turn a fan into a true air conditioner.
