Do you need a ceiling fan in your house when you have an exhaust fan? Conversely, you need an exhaust fan when you have a ceiling fan? Well, do not make the mistake of confusing these two devices to be the same. Both these devices are fans. Yet, there is a huge difference between the functions and the uses of these two devices.
The function of the exhaust fan is to suck air out of the house. Of course, the entire process will never be completely efficient because the windows are open and there always will be inflow and outflow of air. However, the purpose of the exhaust fan is to speed up the process.
Once the exhaust fan is powered on, it shall start sucking air out of the house. This shall automatically facilitate the entry of fresh air into the house. The entire process is done in a very subtle manner and you will never feel a strong breeze or gust of air going out of your window.
Yet, if you have a very strong smelling agent in the room, it will gradually be replaced by normal fresh air. The purpose is to not just circulate the air but to expel stale air and bring in fresh air.
On the other hand, the function of the ceiling fan is to circulate air inside the room. The air near the floor and the air near the ceiling is constantly circulated. Does this mean that the ceiling fan does not facilitate exchange of air? Definitely.
When the circulation of air takes place, it is obvious that air that is situated near the window would obviously be pushed out and fresh air would come in. Yet, this is an ancillary and incidental consequences of having a ceiling fan in the house.
In most cases, this circulation of air combined with exchange is sufficient. Yet, in rooms where odors and smells are very strong, it becomes essential to have an exhaust fan. Ideal situations and rooms are bathrooms and kitchens. You cannot afford the smell of food to linger for a very long time, can you?
It is going to settle on your clothes and you will smell like the dish you have prepared. To avoid such issues, you can simply suck the air out. This is also very useful if the air inside the house is very humid. Dry air will come in and will help you control the atmosphere of your house better.
