ROOFTOP EXHAUST SYSTEM FOR EXHAUSTING AIR FROM A BUILDING
The present invention entails a rooftop exhaust system for a building. The exhaust system includes a motor that is configured to directly drive a fan. The fan during the course of operation generates a negative pressure on the upstream side of the fan. This negative pressure is utilized to induce outside cooling air into a shroud that partially encloses the motor. Cooling air passing through the shroud contacts the motor and heat associated with the motor is transferred to the cooling air after which the cooling air exits the shroud.
