We’re in the middle of summer and we’re seeing extreme temperatures every two-thirds. Heat waves have become an everyday thing and therefore it is necessary to find ways to cool off at home. The two traditional options are: fan or air conditioning. However, there are big differences between them both in terms of environment, health and economy. no doubt which The best: admirer.
When it comes to health, its use fan is healthier than air conditioner in almost all circumstances, because Air conditioning can dry out the air and cause persistent colds as well as respiratory problems. Instead, the fan simply moves the air without changing its physical conditions. Only in extremely hot and humid environments, air conditioning can be preferred to prevent heat stroke and other heat-related health problems.
Not only this: Air conditioning can also be a suitable source of bacteria and fungi. If not properly cared for, this can worsen respiratory problems. However, in extremely hot and humid environments, air conditioning can help people with heart or respiratory diseases.
Therefore, it is always preferable to use a fan and keep the windows open for good ventilation in general, but air conditioning may become necessary if the heat is too intense.
Less CO2 emissions
From an environmental point of view, there is no doubt about the advantages of the fan over the air conditioner. This is revealed by a study made public last year by scientists from the University of Sydney (Australia). The research concludes that the energy savings (and CO2 emissions) in fans exceed 70%.
To get their results, the researchers ran tests over a year using supercomputers to determine the effectiveness of both cooling systems on a 150,000-cell raster grid.
So they discovered The occasional use of fans with an air velocity of 1.2 m/s with air conditioner use resulted in a 76% reduction in energy use compared to using air conditioners alone.
Special, the difference was 5,592 GWh vs 1,344 GWh. At the same time, the greenhouse gas emissions associated with both systems are 5,091 kilotonnes and 1,208 kilotonnes, respectively, indicating that the fan is more sustainable.
“By increasing the movement of air in a ventilated interior, you can feel the same comfort felt at a lower temperature when using air conditioning. This is something most people can do to help reduce the massive emissions associated with cooling homes and interiors,” write the study authors.
The most economical fan
Also, precisely because of the lower energy consumption, the use of a fan will always be more economical than an air conditioner. Initially, fans are much cheaper, and both maintenance and repair are much cheaper.. The costs of these factors increase significantly when it comes to air conditioning equipment.
at the same time Cheaper to install fans, even for ceiling-mounted modelsIt is increasingly used to distribute cooling actions more evenly than standing ones.
in relation to energy consumption, fans consume much less energy than air conditioners. According to the Levante-EMV newspaper, a traditional mid-range fan consumes between 10 and 100 watts, while an air conditioner in the same segment consumes between 1,000 and 5,000 watts, depending on capacity and energy efficiency. The Prensa Iberica group.
Air conditioner, on the other hand, uses a compressor to cool the air, which consumes much more energy than moving the air with a fan. In general, using a fan is a much more energy efficient option than an air conditioner.
