Abstract

The air diffuser for the ventilation system consists of an upper air box with ball jet diffusers, two perforated outer walls, two perforated inner walls, a body structure, and a vertical air box for directing cool air from the directional walls to the upper air box. The vertical air box comprises a front and rear wall, a first perforated baffle plate (with a central hole), a second perforated baffle plate (with a central hole), a third perforated baffle plate (with a central hole), and perforated rectangular walls with rounded ends. A directional wall directs the airflow vertically. The first and second air deflector assemblies are also included, along with a support base for mounting and securing to the body structure.
