Ceiling fans can be a great addition to any home or room. Ceiling fans can provide a room with comfortable air movement, appropriate lighting, and a decorative touch. Choosing the proper ceiling fan or fans for your home is an important decision. This guide will help you understand the way ceiling fans work and the different styles and options available.
Why Purchase A Ceiling Fan? The primary purpose for a ceiling fan is to provide ventilation and improved air circulation throughout a room. Proper air circulation is beneficial because it can improve the effectiveness of your home cooling system during warm weather and your home heating system during cold weather.
For cooling purposes, the breeze created by the ceiling fan will bring the cool air to you and create a “wind chill”. The “wind chill” will make your environment seem cooler than the actual temperature of your home. Therefore, you can set your thermostat at a higher temperature in the warm summer months for energy savings and still remain comfortable.
Our grade school science classes taught us that light warm air rises above cold dense air. For heating purposes, the ceiling fan will circulate the air to bring the warm air down from the ceiling so that you can enjoy it in your living space. Therefore, you can set your thermostat at a lower temperature in the winter for energy savings.
Ceiling Fan Styles
There are basically three major ceiling fan styles: traditional hanging propeller ceiling fans, directional ceiling fans, and rotational ceiling fans.
Ceiling Fan Buying Guide
Traditional Hanging Propeller Ceiling Fans
The traditional hanging propeller ceiling fan is what people normally think of as a ceiling fan. The fan hangs perpendicular from the ceiling and the blade rotation is parallel to the floor. There are hundreds of these ceiling fans in various finishes, blade designs, blade quantities and lighting fixture options to fit every home décor, room size, and room function. Basic traditional ceiling fans are typically the least expensive of all three ceiling fan styles.
Directional Ceiling Fans
Like the traditional propeller ceiling fans, directional ceiling fans hang from the ceiling. The difference between these ceiling fans is that directional fans have the capability of being manipulated to hang at a particular angle to better ventilate a particular area rather than an entire room. These fans are desirable when only one area of a room requires additional ventilation and no additional lighting.
Rotational Ceiling Fan
A rotational ceiling fan is a combination of the first two styles of ceiling fans: traditional propeller ceiling fan and directional ceiling fan. Rotational ceiling fans are normally provided with one or two sets of propellers that rotate independently.
Each set of propellers is provided with its own motor which makes a complete fan. The rotational fan in the photo above is provided with two sets of propellers (or fans). The fans are attached to a horizontal support rod which rotates on a vertical axis. As the propellers turn, the horizontal support rod turns. The position of each fan motor housing can be adjusted to increase or decrease its angle to the horizontal support rod. The entire unit is designed so that horizontal support rod will turn faster as the fan motor angle is increased. Ultimately, the axial rotation speed about the vertical support bar is dependant upon the fan motor speed and the fan motor angle to the horizontal support rod.
Rotational ceiling fans are claimed to circulate air more efficiently for heating and cooling purposes than the traditional propeller ceiling fans. Rotational ceiling fans
