Having been within the ceiling fan business for over 20 years, it’s uncommon {that a} new ceiling fan will get me excited. However whereas researching the effectivity rankings of the newest introductions this yr, one mannequin clearly stood out amongst all others. The Halfway Eco from Emerson Electrical, which is a formidable new Vitality Star Ceiling Fan that’s Over 300% Extra Environment friendly than different fans. This represents a serious breakthrough in ceiling fan efficiency and know-how, setting a brand new commonplace for power environment friendly ceiling fans.
Emerson developed a completely new motor for the Halfway Eco Ceiling Fans referred to as the “EcoMotor TM”. The EcoMotor TM makes use of as much as 75% much less power in comparison with different ceiling fans. The blades have an airfoil form for higher aerodynamics and transfer as much as 40% extra air than typical fan blades. The built-in light makes use of 4 13 watt fluorescent lamps to supply most illumination at a really low wattage ceiling fan with lights remote control B09RJ2DS1S.
With these new improvements, the Emerson Halfway Eco far surpassed the Vitality Star testing necessities established by the EPA. As a matter of truth, the check outcomes show it to be over 3 occasions (or 300%) extra power environment friendly than some other Vitality Star ceiling fans with lights. Which means that the Halfway Eco will transfer considerably extra air whereas utilizing a fraction of the electrical energy making it the last word selection for power acutely aware shoppers who want to cut back their carbon footprint.
Though Emerson doesn’t declare that the Halfway Eco is 300% extra environment friendly than different fans, I made this statement myself after reviewing the check outcomes revealed by the EPA, for ALL Vitality Star Ceiling Fans with lights.
To ensure that any ceiling fan to be Vitality Star certified, it should meet EPA requirements for high quality and sturdiness. However most vital, it should bear a standardized testing process adopted by the EPA to calculate the effectivity of the fan. Through the check, sensors measure the CFMs (Cubic Ft per Minute) of airflow the fan produces whereas recording the quantity of electrical energy it consumes.
The effectivity ranking is calculated by dividing the CFMs produced by the Watts consumed (CFM/WATTS). This data is labeled on the fan packaging of each Vitality Star ceiling fan giving shoppers a standardized approach of evaluating the efficiency between completely different fashions. For such a comparability is vital for individuals who are power acutely aware. As you will notice within the information beneath, there are substantial variations within the effectivity rankings of many Vitality Star ceiling fans.
The information that I used to carry out my evaluation is revealed by the EPA and may be discovered at www.energystar.gov. Should you want to affirm my observations, obtain the spreadsheet below Ceiling Fans with Light Kits named “ceiling_fan_with_lightkit_prod_list.xls”.
Listed below are my findings primarily based that information:
There are 126 Vitality Star ceiling fans in complete, which represents the entire varied finishes accessible for every mannequin. I eliminated the end variations to get to the precise base fashions since every end is only a duplicate of the particular fan. This introduced the whole all the way down to 33 Vitality Star certified ceiling fans with lights accessible within the USA from all manufacturers mixed.
The table beneath represents my findings sorted by probably the most environment friendly to the least environment friendly. The Emerson Halfway Eco is on the prime with an effectivity ranking of 620.20 CFM/Watt on Low Velocity, 476.6 CFM/Watt on Medium and 289.0 CFM/Watt on Excessive.
