There is a lot of heat, not just a little.And sure, we already know it’s summer, but summer is one thing, and the heat makes it impossible to breathe. In the meantime, our air conditioning cost continues to rise. But be careful—these are the times when our creativity is most sharpened, which is why we’re sharing one of our favorite tricks with you today. What more could you want than something cool and cost-effective?
KYL was developed in Singapore by Aileen Ooi and E Ian Siewand, and it uses a simple yet clever physical idea to lower the room temperature without costing an additional peso!
What is KYL?
A cooling system that uses Bernoulli’s principle, which states that when a fluid air accelerates, its temperature and pressure drop. To put it another way, it’s a device that is mounted on the fan section and, because of its design, it speeds up airflow, making the air significantly cooler.
How does KYL work and what makes it so special?
A conventional fan is converted into a passive cooling system by KYL. Although it appears to be a funnel nozzle at first, it is actually an engineering device that speeds up air flow and causes a temperature reduction of up to 1.5 C.
A natural cooling effect is produced when air moves faster and has less pressure when it travels through a constriction, such as the KYL funnel. The best thing about it is that it uses the same amount of energy as the fan and helps lower the air’s humidity.
Installation without complications
The nicest part about this creation is that it’s really simple to use and doesn’t require any special knowledge or tools. It is connected to the fan by means of adjustable straps, and it takes no more than fifteen seconds to observe its effects. It is essentially the same fan, but with improvements.
Sustainable materials
Despite being composed of recyclable materials, KYL contains high-quality parts that are reusable and can be disassembled and cleaned. Cost and environmental savings!
Can it really replace air conditioning?
Although it is nearly difficult to match the strength of an industrial air conditioner, it provides a cost-effective and environmentally friendly substitute for individuals who cannot afford the expenses during these hot months. This is the year’s greatest invention for workplaces, bedrooms, or other small areas where the heat is intense.
How much does a fan consume vs. an air conditioner?
Of obviously, there is a significant difference. A standing fan often doesn’t go above 80 W per hour, whereas an air conditioner can reach 1,000 or 2,000 W.
We need to think outside the box because not everyone can afford to keep the air conditioner running all day!
Internationally recognized
It was chosen as the winner of the Clean Energy Challenge in 2018 by the IKEA Foundation and What Design Can Do (WDCD) because of its practicality and approach to combating climate change at home.
Why should you try it this summer?
Aren’t its practicality, affordability, ease of setup, and environmental protection sufficient justifications? Just as cool as having an air conditioner running all day, but with less money on your bill!
