The right place to install a fan according to science – teach me about science

Summer is here and that means heat, a companion that can last for months. A time to get to know or visit places like beaches or lakes that are relaxing. However, certain areas are subject to extreme heat waves and it is clear that this is not always pleasant for people. How do you resist this? A good percentage of the population choose electric fans, so it is important to know their correct location.

Where is the appropriate place to install a fan? Using a fan in your home can increase air circulation and help keep the room cool. However, this does not mean that it should be placed anywhere, it is convenient to place it where the air flows continuously.

For example, if your room has windows, this is where you should place your fans. The idea is to push the hot air out and let the cool air in. In this way, it also makes sense to think that it will work better if the external environment is cooler than the internal environment. Fans are not recommended for use in closed environments, as they are stirred only with the same hot air.

You can also use a double fan, in this way you seek to create a kind of cross wind that allows more easily the exchange of hot air inside your home with cold air outside. Notably, there are different types of fans and some of them may require specific locations as with the axial flow fan, which is a vertically mounted freestanding fan and used in the home for cooling and ventilation.

Fans or air conditioners? The scientific literature indicates that electric fans can provide efficient cooling for people, with lower greenhouse gas emissions and a lower cost than air conditioning.

Are fans dangerous? The 2019 study advises against Use fans at high temperatures. International organizations have also stated that it is not recommended for use at temperatures above 35°C. Accordingly, fans work well in hot and humid environments, but not when they are hot and dry.

The topic here is a bit contradictory and the researchers haven’t fully agreed yet. Newer study They analyzed a database between 2007 and 2019, in which they concluded that electric fan use, especially in healthy adults, would not exacerbate heat stress on most school days.

An important point in favor of electric fans is that they are less polluting. While air conditioning contributes significantly to greenhouse gas emissions, directly through the leakage of refrigerant gases into the atmosphere and indirectly due to the high demand for electricity. The use of electric fans does not require refrigerants and requires 30 to 50 times less energy to operate. In this case, the healthiest thing for the environment is to use fans.
