NOISE SUPPRESSION SYSTEM FOR AIR HANDLING UNIT

Abstract: an air handling unit includes a mounting frame configured to couple to a fan assembly upstream of an inlet of the fan assembly, relative to a direction of air flow through the air handling unit. the mounting frame includes a plurality of walls defining an air flow path configured to direct the air flow through the mounting frame to the inlet of the fan assembly. each wall of the plurality of walls includes a first mounting flange configured to be attached to the fan assembly and a second mounting flange configured to be attached to a damper mounted to the mounting frame upstream of the mounting frame. a noise suppression system is disposed within the mounting frame and includes sound absorbing material disposed along each wall of the plurality of walls and a plurality of cover panels attached to the plurality of walls to encase the sound absorbing material between the plurality of walls and the plurality of cover panels.
