Attic Need Supplimental Cooling Fans
A fan cools things.
Attic need supplimental cooling fans. Alternatively install passive vents such as gable soffit and ridge vents which are openings in the roof that allow hot air to escape. Additionally by aiding your central air conditioner fans lessen the workload of your hvac system thus reducing the helping to lengthen its lifespan. The attic cools and the attic fan goes off. A whole house fan can be run from early evening to early morning effectively cooling the structure of your home using the cool free outside air.
By installing ceiling fans or using floor fans you can help to better distribute the cold air that comes from your air conditioner. In a properly designed passive system air enters through the soffit. That said air resistance and interference such as vent grates reduces the area of true ventilation. The a c usage goes down.
When combined however they form a perfect union. Attic ventilation fans help cool air your attic by pushing out the stifling hot air from inside the attic and bringing in cool air from outside. In other words the entire vent opening doesn t count as vented space. The ventilation that controls moisture from condensation and regulates the temperature in your attic relies on air circulation.
So it s natural to think of cooling the attic. Make sure that your attic is well insulated. This prevents hot air from seeping into your home and driving up the temperature in the living space which reduces the load on your air conditioner. They have thermostats that turn the fan on at a recommended preset temperature of 100 110 degrees.
With a hot attic the ceiling heats the building. Whole house fans combined with ceiling fans and other circulating fans provide acceptable summer comfort for many families even in hot weather. Without this open space the fans will not move much air. Ventilation fans ventilation fans or powered attic ventilators are designed to cool the attic pushing out the hot attic air and rushing in a flow of cool outside air.
In addition to whole house fans the ducts of your central heating and cooling system can be modified to provide whole house cooling. Whole house fans need windows and doors open and attic fans need lots of soffit vents to suck cooler outdoor air up into the hot attic. Generally speaking you need a ratio of 1 300 where for every 300 square feet of ceiling space you need 1 square foot of attic ventilation. Attic fans and whole house fans together can help with home ventilation but they serve different purposes.
