Abstract (en)
[origin: CA2669257A1] A conditioning apparatus (1) for the air supply stream of a drying chambe r (2) of an enameling line has a fresh air duct (8) and an air supply duct ( 10) connected thereto through which a fresh air or air supply stream can be directed into the drying chamber (2); an exhaust air duct (13) and an escapi ng air duct (14) connected thereto through which an exhaust air stream can b e guided out of the drying chamber (2) or out of an escaping air duct into t he surrounding area; an absorption or adsorption device (4) which is arrange d in the escaping air duct (14) and in the air supply duct (10) and in which the air supply stream can be dehumidified and heated to a predetermined lev el of humidity by means of the escaping air stream; a device for heat recove ry (6) which is arranged upstream of the absorption or adsorption device (4) in the escaping air duct (14) and which is arranged downstream of the absor ption or adsorption device (4) in the air supply duct (10) and in which the air supply stream which is dehumidified and heated in the absorption or adso rption device (4) by means of the escaping air stream emitted from the dryin g chamber (2) can be cooled; an aftercooler (7) which is arranged downstream of the heat recovery device (6) in the air supply duct (10) and in which th e air supply stream which is precooled in the heat recovery device (6) can b e cooled to a temperature required for entry into the drying chamber (2); an d an afterheater (5) which is arranged in the escaping air duct (14) downstr eam of the heat recovery device (6) and upstream of the absorption or adsorp tion device (4) and in which the escaping air stream can be heated to a temp erature suitable for the regeneration of the absorption or adsorption device (4). To reduce the use of energy for the operation of the conditioning appa ratus (1), it is suggested that a recirculating air duct (11) branch off fro m the exhaust air duct (13) coming out of the drying chamber (2) at a first junction place (12); and that through said recirculating air duct, a part of the exhaust air stream coming out of the drying chamber (2) can be brought, together with the fresh air stream, as a recirculating air stream in a seco nd junction place (9), and can then be directed through the air supply duct (10) as an air supply stream into the drying chamber (2); and that a precool er (3), by means of which the fresh air stream can be cooled and dehumidifie d, is arranged upstream of the second junction place (9) in the fresh air du ct (8).
