Why 27°C AC + Fan Feels Cooler Than 25°C AC?

Are you looking to stay cool this summer but without breaking the bank on your electricity bill? You might be on the right page of the internet.

Here we found a new study by Japanese researchers that reveals a surprising yet effective solution to achieve better cooling levels with energy saving solution and it is as simple as:

Turn up your AC to 27°C (80.6°F) and pair it with a fan!

This method might not sound accurate to you, but the Chulalongkorn University study reveals that the combination provides better cooling than a solo AC set at a lower temperature (25°C or 77°F).

Here's the science behind AC + Fan On Trick:

You might be thinking about how a fan can help the AC to cool down the room temperature even when the AC is at 27 degrees Celsius which is actually higher than we all set our ACs on. So here's how the trick works:

1. Enhanced Air Circulation: The fan increases air movement which helps to distribute the cool air from your AC more evenly throughout the room. This even distribution of cool air ensures you feel the cool air more effectively and helps the AC cool down room occupants faster, even with the slightly higher AC setting.
2. Energy Savings: By reducing the AC's target temperature to 27°C, you're essentially asking it to work less and use less electricity. This translates to significant energy savings compared to running a solo AC at a lower temperature.

So, the even cool air distribution helps the AC to make your room feel cooler than it would at 25°C and uses less energy to help you reduce your electricity bills.

But the benefits go beyond just cost savings:

1. Reduced Humidity: The air circulation from the fan helps combat humidity, making the air feel more comfortable and cool even at a slightly warmer temperature.
2. Quieter Cooling: Fans are generally quieter than ACs. Using both allows for a more peaceful cooling experience to help you sleep well.
3. Extended AC Lifespan: A less overworked AC translates to a longer lifespan for your appliance translating into less service demand and more efficient usage.

So, you get to save energy, feel more cooler, reduce humidity, and have a quiet cooling experience along with the extended lifespan of your air conditioner, what else do you want to ask for?

I am not just making false claims here, and to make it clear to you, here's a stance from the original case study:

Chulalongkorn University reinforces these findings:

A lecturer at the university named Jessada Denduangboripant, confirms that combining a fan with your AC can reduce electricity bills by 10-30%.

He explained that the air-con compressor works less hard when the temperature is set higher.

This strategy is also endorsed by Thailand's Energy Ministry, and it allows you to maintain a comfortable temperature (around 27°C) with significantly lower energy consumption compared to a cooler AC setting such as at 25°C or lower.

Have more questions? here's a list of a few answers:

1. Is a 27°C AC with a fan really cooler than a 25°C AC alone?

Yes, according to Chulalongkorn University and many other independent studies, the even air circulation from a ceiling fan helps distribute cool air more effectively, even at a slightly higher AC setting. This can make you feel cooler while saving energy.

2.  How much money can I save with this method?

A few studies such as one by Chulalongkorn University suggest a 10-30% reduction in electricity bills compared to using a solo AC at a lower temperature.

3.  What other benefits are there besides saving money?

• Reduced humidity for a more comfortable feel.
• Quieter cooling experience thanks to the fan.
• Potentially extended lifespan for your AC due to less strain.

4.  Will a fan make me feel colder if I turn my AC even higher than 27°C?

There's a limit. While a fan helps with air circulation, excessively high AC temperatures (higher than 27°C) might not be offset by the fan's effect. You should aim for a comfortable temperature with the fan's assistance.

5.  Is there anything else I can do to improve efficiency?

Yes! Regularly cleaning your AC filters can ensure optimal airflow and performance and also helps reduce service costs.

So, the next time you reach for the AC remote controller, remember: to crank it up a notch to 27°C, grab a fan, and enjoy a cool and cost-effective summer without breaking your bank to pay monthly bills just for taking some cool air!
