During the day the sun warms the home. Hot air rises and expands, which means that heat has to exit the home before cooler outside air can come in. Often homes are closed up when we go out for the day, so heat gets trapped inside until we come back in the evening to “air the house out”.
Turning on an A/C means keeping the house closed up, and many local homes aren't designed for efficient cooling.
Turning QuietCool on starts the process of exhausting heat out of the living area and blowing trapped hot-air out of the attic space. This in turn draws fresh air into the home through windows and open doors.
Drawing heat up and out (where it wants to go naturally) means that as it draws in fresh air, this very efficient system cools both living space and attic.
–That’s why it’s called a Whole House Fan.
Because QuietCool is ventilating your home three ways, the whole house fan system will work effectively anytime the outdoor shade temperature (ambient temperature) is in the comfort range, which is normally the case in Hawaii.
Because the system is not refrigerating air, it’s a very cost energy efficient way to cool the home. The control switch allows it to provide on-demand ventilation when you want it, and because QuietCool works with open windows it’s a great fit for our indoor/outdoor lifestyle.
Think of your car parked in the sun. If you were to go out, roll down the windows and just sit, notice it won’t cool off. It’s not just hot air, but the seats, dashboard and steering wheel are hot too. Once you start driving, the large amount of air coming in through the windows takes the heat out of the mass of the vehicle. That is thermal mass cooling.
CFM (cubic feet per minute) is the measure of air that is moved by a fan. Fans with a higher CFM can cool an area more effectively. Your QuietCool system is sized to ventilate the air volume of the room every two to three minutes. This allows the system to achieve lower indoor temperatures and cool the mass of the home.
