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.

In a manner described above, a vehicle capable of suppressing power loss and lengthening of charging time in heating during the remote air conditioning and the preliminary air conditioning is provided.

Abstract: A variable volume induction nozzle is designed for use with a variable speed fan, where fan speed is adjusted in response to variable exhaust gas flow volume in order to conserve energy. In order to maintain a minimum exhaust discharge velocity to ensure adequate plume height, an axially-extendable, upwardly tapered flow-impinging pod within the nozzle creates a variable annular nozzle outlet opening. As opposed to a circumferentially-constricted outlet opening, the variable annular outlet produces a uniform discharge velocity profile conducive to the induction of ambient air through a windband.
