The technical criteria of the ceiling fan
As with any material item, choosing a ceiling fan is done particularly in relation to its technical skills. By stirring the ambient air, the ceiling fan allows the atmosphere to be refreshed quickly, especially during hot weather. During the winter season, it helps maintain a uniform temperature in the room where it is installed. Finally, it purifies the air in your interior, for example preventing moisture from settling.
To make the right choice, a few criteria must therefore be taken into account on the technical side, for optimal use:
- The diameter : the larger the ceiling fan, the more efficient it is. For optimal efficiency, it is advisable to take into account the dimensions of the room. For a room of 9 to 21 m², we opt for a ceiling fan whose diameter is 70 to 110 cm. For a room between 21 and 37 m², a diameter of 110 to 145 cm is perfectly suitable. Beyond that, several ceiling fans must be installed in the same room.
- The blades : a ceiling fan has between 2 and 5 blades. No matter how many, the effectiveness remains the same. It is rather necessary to take into account their inclination (between 6 and 18 °) to determine the power of the fan. The blades can be made of wood, metal or even plastic.
- Speed : It varies depending on the type of fan. The minimum speed of rotation is around 70 to 90 rpm. With 3 or 4 speeds, the fan cools the room faster than an entry-level two-speed model.
- The power : It also differs depending on the model. More ecological and economical than an air conditioner, it is between 50 and 75 W at full power, and between 20 and 30 W at reduced power.
The different trigger modes of the ceiling fan
There are three ways to activate your ceiling fan right now. Again, the choice is made in technical terms but also from a practical point of view. This depends in particular on your ceiling height, the model chosen or even the room in which it is installed.
- By chain: it is the oldest mode, a little dated. Easy to install, you activate the ceiling fan by simply pulling the chain. If your fan is also used as a ceiling light, a second chain turns on the light.
- By switch: connected to the electrical system, your ceiling fan is activated by a switch, like a classic ceiling light.
- By remote control: it is found especially on the most modern models. It allows you to start or stop the ceiling fan, but also to adjust its speed without having to move. It is a very practical model in a bedroom, for example. In these cases, you can also choose a model with timer. This allows you to determine the operating time of the fan.
Ceiling fan with or without light?
Another criterion to take into account before buying your ceiling fan: do you want it to also serve as a light?
You should know that this kind of model will never be as powerful as a classic light, even if it has several bulbs. It is however possible to use your ceiling fan with or without the light function. You can also turn it on as a light fixture, without activating the blades. This is why there are ultimately very few models without light function on the market.
Light can be supplied by E27 or E14 bulbs on classic models. On more modern models, we find rather LED lighting, more economical.
