It is important to understand that fans do not only eliminate heat but also climbing temperatures. By circulating the air ceiling fans move warm air toward the ceiling and into attic vents while creating a “wind-chill” effect, which adds to the cooling sensation.
Air conditioners are not known to be very energy efficient. Even the most advanced units use more power than other appliances in most homes. According to recent research, around 20% Kilowatt of energy each year is consumed by air conditioners. On the other hand, fans use less energy when compared to the air conditioners. Using low amount of energy does not translate to its inefficiency as many may argue but it translates to bringing down the temperatures of the room to 18 degrees. While serving an energy saving function, fans can also accentuate the style and decor in your home or office. This is because the ceiling styles and fans have come a very long way.
Things to consider before buying a fan.
At first glance it may be hard to see why one fan costs $50 and another costs $600. Sometimes the price may vary because of the design and style of the fan but mostly, the Quality is the main determinant of an expensive fan. Quality superior fans pay attention to blade angle, use higher quality internal components and are better engineered. We are not saying that cheap fans will not function, but they will function at a very short period. A wobbling fan generally wears out fast.
More to this is that the air moved by high quality, expensive fan is more than that moved by the low quality blades. Ideal blade angle for a traditional ceiling fan is 12-16 degrees. the cheap fans have blades of between 12 to 16 degrees only.
Where to place fans
Traditional fans should be hung in the center of a room. The blades have to bwe 8 inches from tha floor for optimum air circulation. Low profile fans, for lower ceilings, and lengthening stems, for higher ceilings are generally available with fans to ensure they are mounted at their ideal height.
Directional fans, as the name implies, are stationary fans designed to cool a specific location or area. However, to ensure that a wider area is cooled the directional fans may just swivel. Most of these blades move more air as they have powerful motors and blades inbuilt in them. These fans can be a good addition to cool a room that already has a traditional fan fitted on them.
However, there is a third type of fan that can be used to cool the room known as the rotational fan. The difference between the traditional fan and this one is that in place of blades, it has horizontal stems.
