Abstract
Energy conservation structure is provided for a controlled environment room having an opening in a wall thereof through which work is passed and through which room air under pressure may be discharged from the room, thereby to prevent contamination of the room air by contaminants in outside air entering the room through such opening, the energy conservation structure including structure providing suction adjacent to the wall opening to induce the flow of room discharge air thereto, the latter structure being constructed and arranged for communication with structure and apparatus for recycling the discharge air of such induced flow to the controlled environment room.
Claims13
Energy conservation means for a controlled environment room maintained at superatmospheric pressure therein and having an opening in a wall thereof through which work is passed and through which room air under said pressure is discharged from the room, thereby to prevent contamination of the room air by contaminants in outside air entering the room through said opening, comprising means for providing suction proximate to said opening to induce the flow thereto of said room air being discharged under said pressure, and means communicating with said suction-providing means for recycling the discharged air of said induced flow at superatmospheric pressure to said room.
In an air supply system for a controlled environment room maintained at superatmospheric pressure therein, including means for filtering, conditioning, and blowing return and makeup air for supply at superatmospheric pressure to said room, said room having an opening in a room wall through which work is moved between the outside and the inside of the room, and through which room air under said pressure is discharged from the room, thereby to prevent contamination of the room air by contaminants in outside air entering the room through said opening, energy conservation means comprising means for providing suction proximate to said opening to induce the flow thereto of said room air being discharged under said pressure, and means for conducting the discharged air of said induced flow to said filtering, conditioning, and blowing means.
In combination with a controlled environment room maintained at superatmospheric pressure therein and having an opening in a wall thereof through which work is passed and through which room air under said pressure is discharged from the room, thereby to prevent contamination of the room air by contaminants in outside air entering the room through said opening, energy conservation means comprising means for providing suction proximate to said opening to induce the flow thereto of said room air being discharged under said pressure, and means communicating with said suction-providing means for recycling the discharged air of said induced flow at superatmospheric pressure to said room.
In combination with a controlled environment room maintained at superatmospheric pressure therein and having an opening in a wall thereof through which work is passed and through which room air under said pressure is discharged from the room, thereby to prevent contamination of the room air by contaminants in outside air entering the room through said opening, a work conveyor extending through said opening, energy conservation means comprising means for providing suction proximate to said opening to induce the flow thereto of said room air being discharged under said pressure, and means communicating with said suction-providing means for recycling the discharged air of said induced flow at superatmospheric pressure to said room.
