Patent attributes
The invention concerns an air handling unit (1) comprising a structural frame (3, 5, 19b, 19c) supporting a housing made of flat insulating panels (7, 7b, 7c) and being divided in at least two modules (2b, 2c) enclosing air handling components, the modules (2b, 2c) being attached together by fastening systems (15) comprising a first portion (151) integral with a first module (2b), attached to a second portion (153) integral to a second module (2c). The first and second portion (151, 153) are formed by identical mechanical parts each comprising a conical protrusion (1511, 1531) and a conical recess (1513, 1533), and the first and second portions (151, 153) are respectively mounted on the first and second modules (2b, 2c) so that the conical protrusion (1511) of the first portion (151) is received in the conical recess (1533) of the second portion (153), and that the conical recess (1513) of the first portion (151) receives the conical protrusion (1531) of the second portion (153).
