How was everyone's celebration? I hope that every had a great countdown with your families and loved ones. I bet that many of you also has some new year resolution or personal goals to achieve. For me, I hope to help as many people as possible in seeking not only for environmental friendly living style but also to help reduce their utility billings.
During the countdowns, there were so many people in the public areas. All the massive jams kept me from leaving my comfort zone, so I'd spent the night with my family at home. We were enjoying all the New Year's movies, in a comfortable couch, under a ceiling fan. Just when the movie went into advertisement, I'd stretched my neck and as I looked up, I was wondering: is there any possibility for us to do anything for the ceiling fan to operate efficiently?
Well, there is nothing impossible in the Information Age and I am going to share what I'd learned in the World Wide Web.
What Are Ceiling Fans?
Circulating fans include ceiling fans, table fans, floor fans, and fans mounted to poles or walls. These fans create a wind chill effect that will make you feel more comfortable in your home, even if it's also cooled by natural ventilation or air conditioning.
Ceiling fans are considered as the most effective of these types of fans, because they effectively circulate the air in a room to create a draft throughout the room. If you use air conditioning, a ceiling fan will allow you to raise the thermostat setting for about 2.2°C with no reduction in comfort. In temperate climates, or during moderately hot weather, ceiling fans may allow you to avoid using your air conditioner altogether. Install a fan in each room that needs to be cooled during hot weather. Turn off ceiling fans when you leave a room because by creating a wind chill effect, fans cool people and not the rooms.
How to Design and Install It Correctly?
Ceiling fans are only appropriate in rooms with ceilings at least eight feet high. Fans work best when the blades are 7 to 9 feet above the floor and 10 to 12 inches below the ceiling. Fans should be installed so their blades are no closer than 8 inches from the ceiling and 18 inches from the walls.
Larger ceiling fans can move more air than smaller fans. A 36-inch or 44-inch diameter fan will cool rooms up to 225 square feet, while fans that are 52 inches or more should be used in larger rooms. Multiple fans work best in rooms longer than 18 feet. Small- and medium-sized fans will provide efficient cooling in a 4- to 6-foot diameter area, while larger fans are effective up to 10 feet.
A larger blade will also provide comparable cooling at a lower velocity than a smaller blade. This may be important in areas where loose papers or other objects will be disturbed by a strong breeze. The fan should also be fitted to the aesthetics of the room—a large fan may appear overpowering in a small room. A more expensive fan that operates quietly and smoothly will probably offer more trouble-free service than cheaper units. Check the noise ratings, and, if possible, listen to your fan in operation before you buy it.
Window Fans- Alternative
Window fans use little energy and can provide effective cooling in many climates. Window fans are best used in windows facing away from the prevailing wind and exhausting hot air from your home. To cool as much of your home as possible, tightly close the windows near the fan and open the windows in rooms far from the fan, preferably on the windward side of your home. Windows located at near cooler, shaded outdoor areas provide the best intake of air.
In multi-level houses, the fan should be located on the upper level if possible, and the open windows should be located on a lower level. If that's not practical, you may want to independently ventilate each level of your home with separate fans.
Depending on the layout of your home, you might want to use several window fans working together to pull the air through your home. For instance, fans in several upstairs bedrooms will assure that each bedroom is cooled, and will work together to pull air in through the rest of your home.
What To Look For When Purchasing?
Three rules for getting the most energy efficiency out of your ceiling fan. If you want to get the most energy efficient of your ceiling fans, there are only three simple rules you need to know:
- Get a fan with a high efficacy
- Get the biggest fan you can have
- Turn off fans when you're not in the room
On the sizing recommendation, just make sure you meet all the specified clearances. Then you can get the biggest one that makes sense for the room. Do your research, follow these three rules, and your new ceiling fans will help you to be more energy efficient in your home, not less.
