Air treatment and sound reduction system

A return air sound reducer for use with an air treatment system, wherein the air treatment system includes a supply air opening and a return air opening, comprising:

• a housing defining an interior return volume, said housing including a return opening for receiving air from a room in which the return air sound reducer is positioned and a return air opening for communication with the air treatment system;
• a layer of sound reducing material applied to one or more inside surfaces of said interior return volume;
• and
• a layer of perforated material disposed over said layer of sound reducing material.

An air treatment system, comprising:

• a wall mount HVAC unit including a supply air opening and a return air opening;
• a supply air sound reducer in communication with said supply air, said supply air sound reducer including a housing defining a supply interior provided with sound reducing material, said sound reducing material overlaid with a layer of perforated material;
• and
• a return air sound reducer in communication with said return air opening;
• said return air sound reducer including a housing defining an interior return volume, said housing provided with sound reducing material applied to one or more inside surfaces of said interior return volume and a layer of perforated material disposed over said sound reducing material.

An air treatment system, comprising:

• a wall mount HVAC unit including an integrated sound reduction plenum for reducing noise generated by the operation of the unit and further including a supply air opening and a return air opening;
• a supply air sound reducer in communication with said supply air, said supply air sound reducer including a housing defining a supply interior provided with sound reducing material, said sound reducing material overlaid with a layer of perforated material;
• and
• a return air sound reducer in communication with said return air opening;
• said return air sound reducer including a housing defining an interior return volume, said housing provided with sound reducing material applied to one or more inside surfaces of said interior return volume and a layer of perforated material disposed over said sound reducing material.

A supply air sound reducer for use with an air treatment system, wherein the air treatment system includes a supply air opening and a return air opening, comprising:

• a housing defining a supply interior, said housing including a supply base portion and a supply end portion extending from said supply base portion;
• one or more mid-structure disposed within said supply interior and being generally aligned parallel to air pathways through said housing;
• sound reducing material applied to one or more inside surfaces of said supply interior and a majority of surfaces of said one or more mid-structure;
• and
• perforated material disposed over said sound reducing material.

A return air sound reducer for use with an air treatment system, wherein the air treatment system includes a supply air opening and a return air opening, comprising:

• a housing defining an interior return volume, said housing including a return opening positioned for receiving air from a room in which the return air sound reducer is located and a return air opening for communication with the air treatment system;
• sound reducing material applied to one or more inside surfaces of said interior return volume;
• a mid-frame member disposed within said interior return volume;
• one or more sound reducing structure attached to said mid-frame member to subdivide said interior return volume into at least first and second passageways.

An air treatment system, comprising:

• a wall mount HVAC unit including a supply air opening and a return air opening;
• a supply air sound reducer in communication with said supply air, said supply air sound reducer including a housing defining a supply interior provided with sound reducing material, said sound reducing material overlaid with a layer of perforated material;
• a return air sound reducer in communication with said return air opening;
• said return air sound reducer including a housing defining an interior return volume, said housing provided with sound reducing material applied to one or more inside surfaces of said interior return volume and a layer of perforated material disposed over said sound reducing material;
• and
• a sound reducing mid-structure disposed in said supply interior and said interior return air volume to define more than one air pathway in each of said supply interior and said return air sound reducer.
