Box Fan Energy Consumption

This high performance industrial fan can help users save money while reducing energy consumption in their homes and offices.

Box fan energy consumption. 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. The average floor box fan uses 100 watts of electricity. This information is usually found on the back of the appliance or on a tag affixed to the cord. You can see how much more efficient a fan is than an air conditioner using my data here.

A dc fan as opposed to an ac fan running directly on the 110 volt alternating current coming out of your wall outlet is. The ideal power consumption for a fan without losses can be expressed as pi dp q 1. 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. Like all fans a box fan s power is measured by how much air movement it provides.

Based on our calculations this means that it costs far less than 0 01 per hour to run making it extremely economical. Energy costs of fans fans in general do not consume a lot of energy. A simple method for calculating the wattage of any electrical device is to multiply the amps times the volts. 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.

I was blown away with what i measured. Box fan power consumption tends to be pretty low. For example a box fan that s rated at 2 000 cfm will cool a room of 2 000 cubic feet in one minute.
