This breeze will be carried through your home to each QuietCool whole house fan that is on and in use; thus beginning the cooling process. At the same time, the cooler outdoor air will be brought into the attic and pushed through the attic vents causing the hot stale air in the attic to be exhausted. Exhausting the hot air inside your attic will allow your home to stay cooler throughout the day.
As it gets later in the evening, and even cooler outside, we recommend opening more windows in other rooms of your home. Then at bedtime, close all the windows in the home except those in the bedrooms that are occupied. This will provide each room with a cool breeze as long as needed. If a QuietCool House Fan is installed in each bedroom as we recommended, the homeowner can enjoy the breeze and your privacy with your door closed.
Note: When using the QuietCool system, be sure to not open too many windows or open any windows too wide, as this will lessen the cooling breeze that is felt. There is a “sweet spot” when window opening(s) throughout the home is “just right” to cause a nice active breeze to be felt at each open window.
What do many people do when they come after work and it is really hot outside but cool outside? They open their windows instead of turning on their A/C so they can draw in that cool air. These open windows create a cross breeze and cool the home through thermal mass cooling.
The “passive” cross breeze described above becomes an “active” breeze for QuietCool homeowners and this is the key to thermal mass cooling. Passive breezes within a home will eventually cool the ambient air to a comfortable level but will not move enough air to cool the mass within the home.
When correctly sized, a QuietCool system will fully exchange the entire air volume of a home 15-20 times per hour, or about one full air exchange every 3 to 4 minutes. The “active” breeze is how QuietCool thrives.
Mass “cooling” results because the QuietCool system is removing stale, hot air and replacing it with fresh cool air. All of this is occurring at a high rate of speed and volume, 15-20 times per hour, which is why it works so much better than a simple cracked window.
Therefore, instead of recycling hot, stale ambient air through a closed-loop air conditioning system, the QuietCool system is exchanging hot, stale ambient air with fresh, cool outside air, through an open-loop whole house ventilation system… and at a fraction of the cost of running an air conditioner.
Net Effect of Cooled Mass
A “cool mass” home does not reheat as much or as quickly as a “hot mass” home. Within a day or two of installing a QuietCool system, homeowners are amazed when they come home after work and their house is still cool from the night before!
The reason the home remained cool was that the mass of the home had been cooled by a QuietCool system and thus did not reheat as rapidly as it typically would.
QuietCool is truly a revolutionary product that allows people to save money by turning their A/C off and turning their QuietCool system on!
