Energy use ceiling fan vs air conditioning.

At typical utility rates a central air conditioner costs 43 cents per hour to operate. If you live in singapore you are likely familiar with the high humidity and the sweltering heat that is at least dissipated in part by the abundance of greenery all over the city. The right way to use a ceiling fan to save money on summer air conditioning bills. Fans can t match the raw cooling power of air conditioning units especially in warm climates but the air circulation provided by ceiling fans or a whole house fan can make a house feel substantially cooler for a fraction of the energy cost of a central ac unit.

June can be unbearably hot in singapore which has a tropical rain forest climate. The use of ceiling fans is so effective at reducing energy consumption that the environmental protection agency epa recommends using them to reduce or eliminate the need to use air conditioning. Energy costs of fans fans in general do not consume a lot of energy. And the watts used for an air conditioner is 467.

Ceiling fans help cool a room by moving air which causes evaporative cooling. In an effort to motivate every american to reduce energy consumption by turning off their central air conditioning systems and relying solely on fans. I will assume for arguments sake that no one is honestly considering getting ceiling fans instead of air conditioning as this would be a poor choice unless you lived in the north like bozeman montana where it is cool most of the year. One of the things that i would have considered would be that i would be using 5 fans in place of one air conditioner.

If you were using fans without any air conditioning then of course fans are cheaper. Yes max in terms of power consumption ceiling fans are more efficient than air conditioners however they don t necessarily have to cost the same or more than an air conditioner. Fans range in size from 36 inches to 56 inches using 55 to 100 watts a typical 48 inch ceiling fan will use 75 watts. Click calculate to find the energy consumption of a 48 inch ceiling fan using 75 watts for 3 hours a day 0 10 per kwh.

There are ceiling fans with high cubic feet per minute cfm available at affordable price points. Ac why ceiling fans are here. Since even the most efficient ac is more of an energy hog than any ceiling fan the amount of electricity you need to run a fan is less than what you d need to keep your air conditioner running at cooler temperatures all day. Sometimes running both a fan and an air conditioner gives you the benefit of air conditioning at a lower cost.

So with that said 5 fans on high use 87 watts each so the total watts for 5 fans is 437 watts. So in real time there is not much different from fans to air conditioner.
