Abstract: A centralized fresh air cooling system that operates with outside air that vents inside house air into the attic of a house or building. A damper redirects air from the output of the central air circulator to the attic area to blow the hot attic air out of an attic. A typical central air circulator can replace the air within a house or building five to ten times an hour. They system can be retrofit to most central air systems by replacing the thermostats and installing the damper between the air circulator and the house or building ducting. Outside cooler air is drawn in windows or other openings in house or building, into the air circulator returns and then into the attic. The system uses multiple sensors and control mechanism to ensure optimal energy savings.
