Think of a fireplace. What’s hotter the flame or the coals? The coals. After the coals burn down, what keeps the air warm in the house? The big thick bricks in the fireplace, right? The bricks have all that radiant heat stored inside them to heat the air in your home.
In the summer the attic in your home can heat up to 150 degrees. When this happens, all that radiant heat transfers down through the studs into the drywall. This causes the air in the room to heat the room. Your air conditioner works on a closed system which cools the air down, but not the hot mass of the home. The hot mass of the home heats up the air when your air conditioner turns off, again and again.
This is how a QuiteCool whole house fan works. In the late afternoon when the air temperature is cooler, open up a couple of windows four to six inches wide. Next, turn on your QC fan on high. This will pull the outside cooler air across the room cooling down your carpet, and furniture, all at the same time. This will push all the hot air out of your attic. The moving cool air makes the room feel like it is 10 degrees cooler, i.e. 78 outside feels like 68 moving through the house. When you go to bed, turn the fan to low. You leave on low for four to eight hours, cooling the mass of your home. This will remove all the radiant heat out of your home. The next morning when you leave your house, close your windows, and close your blinds. Then when you come home later in the day, you arrive to a much cooler home.
Examples:
The “passive” cross breeze described above becomes an “active” breeze for QuietCool homeowners. 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 window which is slightly cracked open.
Therefore, do not recycle hot, stale ambient air through a closed-loop air conditioning system. Instead use a QuietCool system to exchange 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.
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!
