The movement of air across your skin helps remove body heat and creates a cool feeling. This is how the body exchanges heat. Much like a fan blowing across a series of cool coils in a chilled water air conditioning system, a fan with an air cooler can help decrease the temperature of the moving air. These tips to stay cool can create a more comfortable atmosphere while saving energy.
Building an Ice Fan Cooler
Placing ice in front of a blowing fan can help decrease the temperature of the air. An ice fan cooler is a quick way to keep you cool on a hot day. It is appropriate for use in an immediate area and will not work well for cooling a large space.

- Position a fan within a few feet of where you want to be. Closer is better.
- Either fill a large bowl with ice or fill 2-liter bottles with water and freeze them.
- Place a towel in front of the fan.
- Place either the bottles or the bowl of ice on the towel. The towel will absorb any condensation that builds up on the frozen water vessel. You can use a serving tray to collect the condensation as well.
- Turn the fan to a setting that is comfortable.
Building an Ice Air Conditioner Fan
More widely used in the commercial industry is a fan blowing across a series of cooling coils. In a commercial application, there will be a chilled water system that circulates chilled water through a series of coils. This is also used in some larger residential applications, but a chilled water system is very expensive. The same system principle can be applied to a quick DIY hack using some inexpensive, common items.
- Use a screwdriver or other means to remove the front grille of a large fan.
- Using tie wraps, strap copper tubing to the front grille, covering the entire grille as well as possible. Leave about a foot on both ends of the tubing to make the connection to the vinyl tubing. Be sure it's not so tight that it restricts airflow.
- However you removed the front grille, reinstall it by reversing the process.
- Slip vinyl tubing over the ends of the copper tubing and secure it with hose clamps.
- Attach the other end of the vinyl tubing to a fountain pump.
- Tie-wrap both ends of the vinyl tubing and the power cord together. Be sure to leave a few inches between the two tubing ends, one being the supply and the other being the return. The return should fall higher than the pump.
- Place a pump assembly in a cooler. (The better the cooler, the longer the ice will last.)
- Add the ice and fill the cooler about a third full of water.
- Plug in the pump and the fan.
- Watch the water flow through the vinyl tubing.
- Once both ends of the tubing are full and the water is circulating, turn the fan to the desired setting. You may want to use a towel or something else to catch condensation that may build up on the coils.
Whichever DIY project you choose, you will be more comfortable while using fans to cool a room.
