Abstract
The open grille structure normally directly in front of a condenser coil is replaced with an acoustical barrier which is moved forward of the condenser coil. In moving the acoustical barrier forward, space results at the top, bottom and sides of the unit which can be used to provide inlet openings for inlet air. Acoustical absorption material lines the structure defining the air flow path to the coil. The modified air flow path results in a modified sound path which results in sound attenuation.
