INSTALLATION FOR RENEWING THE AIR OF A WORKPIECE FROM A DOUBLE FLOW THERMAL EXCHANGER HAVING INSIDE

摘要

Installation for renewing the air of a room (1), comprising: - a generator (2) of single-flow air flow disposed outside said room (1), - a heat exchanger (3) double flow disposed within said room or in a wall defining it, the double flow heat exchanger having an inlet opening (4) and an outlet opening (5) for the incoming air flow (10) in the workpiece, an inlet opening (6) and an outlet opening (7) for the outgoing air flow (11) of the workpiece, an internal flow inlet duct (8) connecting the openings of the workpiece; inlet (4) and outlet (5) for the incoming air flow (10) in the room (1), an internal flow outlet duct (9) connecting the inlet (6) and outlet openings (7) for the outgoing air flow (11) of the workpiece (1), and an exchange wall (12), a first face (13) of which forms a part of said internal flow inlet duct (8) , and a second face (14) opposite to the first constitutes a part of the said internal flow outlet duct (9), - an extraction duct (15) of air outside the room (1), connecting the flow generator (2) disposed outside. of the piece, at the outlet opening (7) of the heat exchanger (3) for the flow of air (11) leaving the room, - an inlet duct (16) of air in the room, connecting the inlet opening (4) of the heat exchanger (3) for the flow of incoming air (10) in the room (1) to the outside environment (17).
