The Cost of Air Conditioning Vs. a Fan

According to the US Department of Energy, about 87% of American homes have air conditioning. By contrast, in 1973, only 47% of American homes owned AC.

I can not deny that I am slightly spoiled by the air conditioner. It is difficult for me to sleep comfortably unless it is less than about 72 degrees. I was very relieved in Michigan

I live in an air conditioner since about 10 years old. The only exception is when I spent two tragic hot days at the college dorm.

However, in the article of "New York Times", I recall some useless ways of "introducing big fans", that is, methods of wasting. That's what I would like to do with some numbers

3 ton central air-conditioning equipment (normal cooling system) with operating speed of about 3 kW, operating cost about 36 cents /

I know that fans use less energy than AC units, but do you use less than 1% of energy? Well ... maybe I need to rethink my love for the air conditioner.

Since it makes sense to convert these per-hour costs into more practical terms, I decided to use mathematics. If you think your unit is moving in the middle of the summer's day,

Can I save over $ 128 a month by installing a ceiling fan in my bedroom and reducing myself from AC? It is amazing!

Even setting a window in the room can save you as much as you can sleep (the biggest obsession for AC in the summer), save $ 78 a month.

I love AC, do not get me wrong. But recently I opened windows more frequently, no. I like outdoor sounds, I really like fresh air.

When it is thought that 25% of the electricity consumed in American homes is used for the power of air conditioning equipment and most of electricity comes from carbon-rich coal, the time comes to reconsider our love for AC maybe. If you call yourself an environmental guard, it is hard to justify the AC.

Regardless of whether you switch to a ceiling fan, a window, a fan in the house, or a combination of them, you can start thinking about your love for the air conditioner. I will do it. be careful

It is a classic comparison of apples and oranges comparing fan operating costs and air conditioning costs. Fans and air conditioners are completely different. Fans do not lower the temperature; it simply moves air to the skin faster. This will evaporate sweat and make you feel cooler, but at some point you will feel uncomfortable no matter how big you use fans. At 90 degrees, the fan sends 90 degrees of air to the skin. This is quite different from using an air conditioner to lower the room temperature to a more comfortable 75 or 78 degrees.

If you cool down the house without using the air conditioner in the summer, consider attaching a fan to the house. Attic fans can blow out warm air while sucking cold air into the wine cellar, and the ceiling follower helps to evenly distribute air to your area.

Driving a fan is always much cheaper than driving an air conditioner. Remember, they are doing two things. In some cases fans are enough; in other cases you need air conditioning. Sometimes, using fan and air conditioner at the same time, you can gain benefits of air conditioning at lower cost. One disadvantage of DC fans is that they are more expensive to purchase than AC fans. However, over time, you can save money by using a DC fan. Recent DC fans usually operate at maximum speed and cost 1 penny per hour. It takes about 5 dollars a month to leave such fans 24 hours a day fast. Medium speed, the cost may be low
