Environmental improvement system
First Claim
1. An environmental improvement system for placement within a room bounded by a floor and a ceiling and having an open volume from the floor to the ceiling, the environmental improvement system comprising:
- a duct system that extends through the open volume of the room substantially from the floor of the room to the ceiling of the room;
said duct system comprising a base unit at a first end of said duct system terminating proximate the floor of the room, a support unit at a second end of said duct system terminating proximate the ceiling of the room, and a duct connecting said base unit to said support unit;
said base unit defining a first opening at said first end;
said support unit defining a second opening at said second end;
at least one reversible fan disposed in said duct system between said first opening and said second opening that draws air from the room into said duct system, through said duct, and discharges said air from said duct system, wherein the reversible fan is configured to selectively convey air in a first direction and a second direction in either a push or a pull mode;
said first opening being adapted to selectively act as a first intake opening through which said air is drawn into said duct system by said fan or as a first discharge opening through which said air is discharged from said duct system; and
said second opening being adapted to selectively act as a second intake opening through which said air is drawn into said duct system by said fan or as a second discharge opening through which said air is discharged from said duct system,wherein a first protective screen is disposed in said duct system proximate said first opening and between said duct and said open volume of said room, and wherein a second protective screen is disposed in said duct system proximate said second opening and between said duct and said open volume of said room, at least one of the first protective screen and the second protective screen incorporating a fragrance.

Abstract
An environmental improvement system for placement within a room bounded by a floor and a ceiling is provided herein. In one embodiment, the system comprises a duct system that extends through the open volume of the room from the floor to the ceiling. The duct system comprises a base unit at a first end terminating proximate the floor, a support unit at a second end terminating proximate the ceiling, and a duct connecting the base and support units. The base unit defines a first opening, and the support unit defines a second opening. At least one fan is disposed between the first and second openings and draws air from the room into and through the system and discharges the air from the system. The first and second openings are each adapted to selectively act as an intake opening or as a discharge opening.

6. An environmental improvement system for placement within a room bounded by a floor and a ceiling and having an open volume from the floor to the ceiling, the environmental improvement system comprising:
-
a duct system that extends through the open volume of the room substantially from the floor of the room to the ceiling of the room; said duct system comprising a base unit at a first end of said duct system terminating proximate the floor of the room, a support unit at a second end of said duct system terminating proximate the ceiling of the room, and a duct connecting said base unit to said support unit; said base unit defining a first opening at said first end; said support unit defining a second opening at said second end; and a plurality of fans disposed in said duct system between said first opening and said second opening that selectively draws air from the room into said duct system through said second opening and discharges such air to said room through said first opening and that selectively draws air from the room into said duct system through said first opening and discharges such air to said room through said second opening, wherein said plurality of fans includes a first fan configured to push air from the room into said duct system and a second fan configured to pull air from said duct system and to discharge the air into the room; wherein the first fan and the second fan are arranged in series; wherein said first fan and said second fan are substantially synchronized to each provide substantially the same volumetric airflow with respect to one another and wherein at least one of said first and second fans comprises a reversible fan, the first fan and the second fan being synchronized by a system controller that can control one or more of fan speed, fan direction, and time of operation for both the first and second fans; and wherein a first protective screen is disposed in said duct system proximate said first opening and between said duct and said open volume of said room, and wherein a second protective screen is disposed in said duct system proximate said second opening and between said duct and said open volume of said room. - View Dependent Claims (7, 8, 9, 10)

11. An environmental improvement system for placement within a room bounded by a floor and a ceiling and having open volume from the floor to the ceiling, the environmental improvement system comprising:
-
a duct system that extends through the open volume of the room substantially from the floor of the room to the ceiling of the room; said duct system comprising a base unit at a first end of said duct system terminating proximate the floor of the room and a substantially vertically extending duct attached to said base unit and terminating at a second end of said duct system proximate the ceiling of the room; said base unit defining a first opening at said first end; said duct defining a second opening at said second end; at least one reversible fan disposed in said duct system between said first opening and said second opening that draws air from the room into said duct system, through said duct, and discharges said air from said duct system, wherein the reversible fan is configured to selectively convey air in a first direction and a second direction in either a push or a pull mode; said first opening being adapted to selectively act as a first intake opening through which said air is drawn into said duct system by said fan or as a first discharge opening through which said air is discharged from said duct system; and said second opening being adapted to selectively act as a second intake opening through which said air is drawn into said duct system by said fan or as a second discharge opening through which said air is discharged from said duct system, wherein a first protective screen is disposed in said duct system proximate said first opening and between said duct and said open volume of said room, and wherein a second protective screen is disposed in said duct system proximate said second opening and between said duct and said open volume of said room, at least one of the first protective screen and the second protective screen incorporating a fragrance. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
