When summer arrives and the heat becomes intense, the first thing we do is turn on the fan and stand right in front of it to try and survive. However, many people don't know that move the hot air The fact that the air is already trapped in the room doesn't do much to lower the actual temperature of the room; we are simply stirring up warm air that gives us a fleeting feeling of relief.
Recently, some tricks that seem contradictory have become very popular on social media platforms like TikTok, such as Point the fan outwardsAlthough it may sound very strange to us, this technique has a scientific basis in thermodynamics and the management of air currents, allowing us to cool the home in a much smarter and more economical way.
The secret to using a fan as an extractor
Most of us make the mistake of facing the fan inwards. The problem is that, without an outlet for the heat, the fan just moves the hot air around. When positioning the unit... looking towards an open windowWhat we're doing is turning it into an extractor fan. This way, the fan pushes the hot air that accumulates on the ceiling and walls out into the street.
For this system to be truly efficient, it is recommended to place the device at about meter and a half away from the window opening. By blowing air outwards, a low-pressure zone is created that allows heat to escape the room more quickly, preventing it from becoming an oven.
The importance of cross ventilation
Getting rid of the hot air is only half the job; now we need fresh air in. This is where the crossed ventilationIt involves opening another window or door at the opposite end of the house so that the cooler outside air flows freely throughout the house while the fan expels the heat through the other outlet.
If we want to optimize this process, ideally we should create a diagonal between the openings so that the air travel Make it as long as possible. If we have two fans, we can make them work together: one extracting heat from the hottest area (usually the one facing south) and the other bringing in cool air from the shadiest part of the house.
When does this trick NOT work?
We can't do this at any time. If the outside temperature is higher than the temperature inside the house, we will be making a mistakeIn that case, by trying to expel air, we will also allow outside heat to enter through the gaps in the window, which will end up raising the indoor temperature instead of lowering it.
The ideal time to apply this method is during the early morning hours, at dusk, or just after a storm. It is crucial to take advantage of that thermal gradient where the outside is cooler than the inside so that the natural airflow works in our favor.
Additional tips and types of fans
Besides positioning, there are other home tricks to enhance the effect. For example, if we place a fan facing inwards in the opposite window, we can position a bowl with ice or frozen bottles in front of the blades. The air passing through the ice cools, simulating a cooling system. smart air conditioning very rudimentary but effective.
It's important to choose the right equipment for your needs. Tower fans are great for small spaces and are safer for children, while pedestal fans allow for greater freedom of movement. adjust height and tilt to direct the airflow precisely. On the other hand, ceiling fans are the most energy efficient and, if they have a winter function, they help to distribute the air more evenly.
To complement the cooling, we recommend keeping the blinds down during direct sunlight. A clever trick is to use aluminum blinds to transfer the cool air from outside to inside without letting in the moisture, thus keeping the environment drier and more comfortable.
Other strategies to combat the heat
- Identify the warmer room and prioritize airflow in that area.
- Avoid placing fans close to walls or in corners to allow for better air circulation.
- Keep the interior doors open so that the airflow does not stop.
- Add indoor plants like the Areca Palm or the Monstera, which help to air purifying and absorb some of the heat.
Controlling airflow in your home allows you to lower the temperature without skyrocketing your electricity bill. By combining heat extraction with a window-facing fan, cross-ventilation, and blocking sunlight during the day, you can create a much cooler and healthier environment, preventing dry skin and the puffiness caused by direct airflow to the face.
