Today I want to share some knowledge about exhaust fan. What is exhaust fan and how the exhaust fan work. 

What is exhaust fan?

A whole house fan is a type of fan, or exhaust system commonly venting into a building's attic, designed to circulate air in a home or building. It is sometimes confused with a powered attic ventilator, which exhausts hot air from the attic to the outside through an opening in the roof or gable at a low velocity.

How the exhaust fan work?

An exhaust fan system provides a number of benefits, including the purifying of air from pollution and excessive heat. Here's is about the operation of basic exhaust fan:

The Basic Procedure

Operating by electricity, the overall procedure involves an electric current that passes through the system to make the motor operate, and, in turn, this causes the fan’s blades to move.

The Blades’ Function

As the fan’s motor runs, the blades will start to turn. The rotation of the blades causes the hot air in the room to be pulled towards the fan and sort of absorbed. This hot air is released outside and in turn cooler and fresher air will start to fill the room. This flow of current will also reduce stagnation of air and is especially important and useful in rooms or areas that lack appropriate ventilation.

The Role of the Thermostat

Most exhaust fans feature a thermostat in their systems. This thermostat comes into play as soon as a certain relatively high temperature is reached inside the room or area. This will cause the exhaust fan to receive a signal. To put it simply, the motor will start running and the blades rotating so as to start working to regulate the temperature in the air until it becomes cooler.

The Fan’s Position

When one installs an exhaust fan, it is recommended that he or she places it as high up as possible. The closer it is to the ceiling, the better. This is because warm air rises upward, and hence, if the exhaust fan is lower down, it will miss a significant part of the hot air in the room and as a result it will not manage to operate as effectively. The more hot air reaches the exhaust fan the more it will be absorbed and eliminated from the room. Consequently, a fresher and cooler room will be achieved more quickly and more efficiently.
