摘要： An air handling unit for a heating, ventilation, air conditioning, and refrigeration system wherein the exhaust air is drawn away from the return air flow by one or more fans located cantilevered on a wall of the air handling unit. The one or more fans may be located within an exhaust hood, through which the exhaust air exits the air handling unit. This air handling unit has a shorter length through elimination of an exhaust fan section. The exhaust air may be drawn through an exhaust damper before being driven into the exhaust hood by the one or more fans. A method can include drawing an exhaust airflow through an exhaust damper, using fans positioned cantilevered on a wall of the air handling unit and directing the exhaust airflow into an exhaust hood mounted on the side wall of the air handling unit.

摘要： Aligning a motor shaft in a fan assembly is described. Aligning a centerline of a motor shaft in a direct drive fan assembly includes selecting a motor from among a plurality of motors and matching a motor-plate from among a plurality of motor plates to the motor, the matched motor plate is based on the selected motor.
Aligning the centerline further includes creating, from the selected motor and the matching motor plate, a motor-plate assembly that has a resulting height, where the resulting height of the motor-plate assembly corresponds to a particular height of a direct drive fan assembly, and aligning the centerline of a motor shaft of the motor-plate assembly to the direct drive fan assembly, where the particular height of the direct drive fan assembly is constant.
