With the summer finally here, keeping cool is a priority. Ceiling fans from Lyon Lighting can help you relax and cool off in an stylish and energy efficient way.
How do you find out how energy efficient your ceiling fan is?
Ceiling fans can be highly energy efficient if they are used properly. Typically, when a ceiling fan is running on high it only uses 60 watts of energy this is a great deal less than a central air conditioning unit which uses 3,500 watts of energy. These fans are not just energy efficient; they can also save you a lot of money – saving you up to 40% in air conditioning costs!
Ten years ago it was difficult to work out how energy efficient the ceiling fan you wanted to purchase actually was but nowadays that information is readily available. On most fan boxes there is an information table that specifies the airflow efficiency.
Airflow is measured in cubic feet per minute (cfm). The higher the number, the more air that is moving. The rate of energy consumption is measured in watts and the quantity of energy that is consumed is measured in kilowatt-hours. The energy efficiency of the ceiling fan can be worked out by dividing the rate of air flow per unit time by the energy use per unit time.
Most of the information in the table on the fan boxes tells you the air flow cfm, the rate of electricity use in watts and the airflow efficiency (cfm/watts). However, this is usually the airflow efficiency for ceiling fans that are running at high speed. If you want to know the airflow efficiency for ceiling fans running at medium or low speed then you need to look at ceiling fans that have an Energy Star label as these will have this information on the box.
It is important to research which ceiling fan you are purchasing as this can affect the airflow efficiency.
It is recommended that ceiling fans with a blade angle of less than twelve degrees wasting energy. This is because the blade is at too low an angle to push the air and the blade will instead cut through the air. You need to purchase a fan that has blades that will push the air upwards or downwards for peak efficiency.
It is also important to think about what ceiling fan you are purchasing. For example, in a room where there is going to be a lot of papers that you don’t want blowing round, such as the study, it is best to purchase a ceiling fan with blades that have an angle of between twelve and fourteen degrees. If you are purchasing ceiling fans for a general use room you want the fan to have blades that are an angle of fourteen degrees or higher.
