Ceiling fans are a stylish and functional addition to your home. Not only do they create a breeze to help keep your home cool in the summer (and reduce strain on your air conditioner) they can circulate warm air in the winter and keep you warm and toasty even when it’s frigid outside.
Choosing the rightceiling fansisn’t simply a matter of picking one out from the home improvement store that matches your decor, though. Everything from the size of the blades to the way the fan is controlled can make a difference in how well the fan performs, its efficiency, and its safety. Before you go shopping, check out this guide to help you choose the perfect fan, and get the most from it no matter where it’s placed.
高度
A fan that hangs too low from the ceiling is a safety hazard, while one that doesn’t hang low enough from a high ceiling won’t give you the breeze and airflow you want. The National Electrical Code requires ceiling blades to beat least seven feet from the floor,so the height of your ceiling will determine the drop of the fan. The lower the ceiling, the less drop you can have.
If your ceiling is only eight feet tall, then your only option is a flush mount fan. As the name suggests, this means that the motor housing is mounted flush against the ceiling. Higher ceilings can accommodate fans with longer downrods; choose the length that places the fan blades 7-9 feet above the floor. If you have especially high ceilings, you may need to invest in an extension rod to hang the fan properly. These rods can extend anywhere from 12 to 72 inches. Always purchase extension rods from the same manufacturer as the fan so they match and are able to be safely used with that model.
Blade Span
Different ceiling fans have different blade lengths, or spans, which influence the airflow in the room. The larger the room, the bigger the blades you need; multiple fans are often necessary for especially large rooms. The scale of the fans should match the size of the room; an especially large fan in a small room will be overwhelming, where small fans will look odd in a large room.
Before shopping, measure the square footage of the room and keep these guidelines in mind:
| Room Size | 推荐ed Blade Span |
| 80 sq.ft or less | 24英寸-42” |
| 100-150 sq. feet | 44”-50” |
| 150-300 sq. feet | 52“ -60” |
| 300 sq. feet and above | 62” or larger |
Control Options
现代吊扇提供各种控制选项。尽管许多人配备了一个老式的拉链，但对于特别高高的天花板来说是不切实际的。壁开关是另一种选择，但是如果风扇有光线，将风扇分开，照明电路很重要 - 否则，您将无法在没有另一个的情况下操作。
It’s becoming more common for fans to come with remote controls, or even Wi-fi control options, for maximum flexibility. As you compare your options, consider the type of control and what works best in your home.
Special Features
最后，比较您正在考虑的房屋的不同风扇的功能。节能型号（查找额定额定能力明星的模型）不仅使用更少的功率运行，而且还可以减少您的加热和冷却账单。例如，在夏天，风扇可以将温度降低多达八度。根据您的喜好，这可能意味着使用更少的空调，或者根本不需要打开AC，尤其是在晚上。在冬季，通过更改风扇叶片的方向，您可以在不冷却房间的情况下更有效地循环温暖的空气，从而使您可以降低恒温器。
That said, different fans have different airflow, and you may wish to install one that has greater airflow if you want to be sure to feel it. High airflow fans are especially useful in larger spaces where you might not feel as much of a breeze from a less powerful fan, including outdoors. If you aren’t as concerned about feeling the airflow, a model that doesn’t create as much of a breeze will meet your needs.
选择与您的装饰相匹配并在家中看起来很吸引人的吊扇很重要，但是看起来不错但不符合空间的技术要求的风扇会导致更多的问题。当您知道房间里有什么作用时，您可以缩小选择范围，并选择空间的完美补充。
