The first and the most obvious factor is the size of the room. If the space is quite big, then 1 ceiling fan may not suffice. On the flip side, if the space is compact, then you can go in for a single fan and you will receive all the ventilation you need.
The next factor that you should consider is the length of the blades. The period of the blade is very important since that will decide the extent to which the atmosphere ventilation will take place.
That’s to say, its surface isn’t completely flat. The curved surface isn’t very sharp but still it exists. This is the simple role of the enthusiast. When the best rated ceiling fans rotate at high rate, the air hits the blade and curves down because of the curve. The final result is that the air near the ceiling is pushed down and the air at the bottom of the space is pushed up.
The fan always rotates the atmosphere and this regulates the temperature of the room, empowers more air from the outside to enter and also leads to transport of air from 1 space to another.
The more the blade more will be the ventilation of air and much more will be the reach of the enthusiast. Of course, it’s the motor which moves the blades. Thus, the length of the blade can also be related to the strength of this motor.
If the engine is quite strong, it can rotate the blades of quite high length. However, that is going to increase the burden of the device and increase power consumption too. That’s folks would rather abide by a conventional sized ceiling fan and go in for greater than one ceiling fan for quite big rooms.
In case you have very major space, you should divide it into two or three parts and you ought to fix a fan for each section. The section can be equivalent in size or can also be unequal if the size of the fan being contemplated differs.
Finally, you need to consider the presence of other cooling accessories such as air conditioners or air jets. If you have a dehumidifier in the room, then the ceiling fan wouldn’t just regulate atmosphere but will even spread humidity all over the space.
