Floor fan, primary efficiency 55 watts, 45 watts is tertiary efficiency, which one is more energy efficient? Why is the 45 watt one a tertiary efficiency?

According to the definition of energy-efficiency level, the higher the energy-efficiency level, the greater the capacity provided under the same energy consumption, that is to say, the same power can provide better working efficiency. Therefore, a 55-watt floor fan with a Class 1 energy efficiency rating should be more energy efficient under the same conditions of use.

On the question of why the 45-watt floor fan is a Tier 3 energy efficient product, it may be because the floor fan is considered a Tier 3 energy efficient product due to its more efficient design and technology, which provides better airflow and comfort at a lower power level. The 55-watt floor fan with Tier 1 energy efficiency, on the other hand, may have a more traditional design and technology that requires higher power to provide the same airflow and comfort.

It should be noted that the energy efficiency rating is only a reference indicator, the actual power saving effect will be affected by a variety of factors, such as the frequency of use, the use of occasions, the use of the way. Therefore, when buying a floor fan, it is recommended to consider a variety of factors and choose a product that meets your needs.
