Box Fan Energy Consumption

Like all fans a box fan s power is measured by how much air movement it provides.

Box fan energy consumption.

For example a box fan that s rated at 2 000 cfm will cool a room of 2 000 cubic feet in one minute. I was blown away with what i measured. This information is usually found on the back of the appliance or on a tag affixed to the cord. The ideal power consumption for a fan without losses can be expressed as pi dp q 1.

The average floor box fan uses 100 watts of electricity. Energy costs of fans fans in general do not consume a lot of energy. What i discovered from my testing is that not only do air conditioners yes it s very obvious use more electricity than fans but they can use up to almost 9 to 10 times as much as a fan does. Box fan power consumption tends to be pretty low.

The addition of a box fan helps lessen the strain on an air conditioning unit by aiding full force air circulation and helping the air to circulate more quickly. A dc fan as opposed to an ac fan running directly on the 110 volt alternating current coming out of your wall outlet is. Based on our calculations this means that it costs far less than 0 01 per hour to run making it extremely economical. Exact energy amounts vary based on the size of the fan s motor but most whole house fans use between 120 and 600 watts according to the national renewable energy laboratory but this is still much less energy than a central air conditioner uses.

Airflow is typically rated in cubic feet per minute cfm which helps indicate how quickly a fan can move the air in a given area. How much electricity does a box fan use. You can see how much more efficient a fan is than an air conditioner using my data here.
