VENTILATION SYSTEM UTILIZING HEAT FROM MOTOR

A ventilation system utilizing motor heat is provided to collect heat generated from a motor driving air supply/exhaust fans to discharge the same to the outside in a cooling mode and to supply the same to an air supply unit in a heating mode, thereby improving heat exchange efficiency. A ventilation system utilizing motor heat includes motor cover(130,131) receiving motors(110,111) for driving air supply/exhaust fans(120,121), and formed with environmental air suction holes(140,141) for inhaling atmospheric air, wherein the motor covers keep heat generated by the motors blocked from an inside of the ventilation system. Venturi tubes(150,151) are coupled with front ends of outlets of the air supply/exhaust fans. A motor heat induction pipe(160) induces internal heat of the motor covers to the venturi tubes. A damper(170) is mounted to the motor heat induction pipe for moving the motor heat in a direction.
