Australia can get quite hot in the summer time, and by hot I mean it can be like living in a furnace. Many people have their different views of how to stay cool and beat the heat so to speak. Some very interesting, some… let’s not go there. But two main ways are either the air conditioning or fan. Let’s have a quick look at how much your air conditioning costs, how they both function to keep you cool and the money involved in operating them. Let’s face it, with rising electricity costs expected over the coming years, keeping cool and saving money can be a problem when thinking of running the air conditioning or the fan.
Air Conditioning simply put, uses refrigeration to lower the temperature inside with a process called ‘Phase Conversion’. This means that when a liquid converts to a gas it will absorb the heat. This heat will flow over the cold, low-pressure evaporator coils. Thus providing cold cool air to be distributed around the room by the air conditioning fans and any unwanted heated air is dispelled externally from the air conditioning unit outside.
Unlike air conditioning, fans do not decrease the temperature in the room. Their role is to simply blow away the heat that surrounds your body. As can be seem in the picture the fan is blowing away the heat that surrounds your body, allowing your body’s natural cooling process to work more efficiently and naturally. As of writing this, the fan I am using is pretty awesome.
Now let’s look at some advantages and disadvantages of Air Conditioning and Fans:
What about the combination of Air Conditioning and Fans?
This is the golden egg when thinking about Air Conditioning vs. Fans! Studies have shown that moving chilled air around, like adding a natural breeze, instead of having it just wasted on the floor can improve cooling effectiveness. This combined process complements each other and furthermore the air con unit itself can be run 2-4 degrees warmer for the same cooling effect. This equates to saving money, which we are all about.
Lastly, let’s look at the electricity consumption of fans and Air Conditioning units on an average usage:
|Standing Fans||60 watts per hour|
|Ceiling Fans||65 watts per hour|
|Split System Air Conditioning||2,200 watts per hour (2.2KW)|
At a peak rate electricity rate of 24.9 cents per Kilowatt (KW) this equates to:
|Standing Fans||0.06Kw x $0.249||$0.015 per hour|
|Ceiling Fans||0.065Kw x $0.249||$0.016 per hour|
|Split System Air Conditioning||2.2Kw x 0.249||$0.548 per hour|
This doesn’t look like much per hour for any of them. However if you compile these costs especially for Air Conditioning unit over a four month period at 10 hours a day, the cost equates to $657.36 just in 4 months. If using a standing fan this equates to $18.00 in 4 months. What a huge difference. Now, I understand 10 hours a day is excessive but it is just an example.
However it all comes down to personal preferences. Some swear by Air Conditioning, others by Fans. If you have the disposable income to use air-con and enjoy it, then why not use air-con. However if you want to save money and stay cool at the same time, then perhaps a fan may be the way to go.
Remember this summer, stay cool, classy and enjoy Australia’s summer furnace… I mean heat.
