The Mechanics Behind Whole House Fans: How Do They Work?
Whole house fans are a cost-effective and energy-efficient way to cool down a house, especially during the summer months. These fans are typically installed in the ceiling of a central hallway or in the attic, and they work by pulling cool air from outside into the house while simultaneously pushing hot air out through the attic vents.
When a whole house fan is turned on, it creates a powerful airflow throughout the house by drawing air in from open windows and doors. The fan then pushes this air into the attic, where it is vented out through the attic vents. This circulation of air creates a cooling effect, lowering the temperature in the entire house.
The fan operates by creating negative pressure inside the house, which forces the hot air to escape through the attic. The incoming cool air creates a breeze that can be felt in all the rooms connected to the central hallway. This allows for quick cooling and ventilation of the entire house, reducing the reliance on air conditioning and saving energy in the process.
In summary, a whole house fan operates by drawing in cool air from outside through open windows and doors, pushing it into the attic, and venting hot air out through the attic vents. This creates an efficient and effective cooling and ventilation system for the whole house.
