Abstract

An air passage (1), which can be connected to an uptake of an air-conditioning installation, with an air-permeable outer pipe (2) which is provided with at least one terminal end plate (3.1) with a central overflow opening, through which the air can flow back into the centre of the air passage (1), and in which means for creating a turbulent flow are provided, is to be developed in connection with the connection means to the uptake in such a manner that it can be operated both in cooling and in heating operation, is simply constructed and can be manufactured economically. To this end, the outer pipe (2) of the air passage (1) is formed by a perforated sheet (5) with a free area of a maximum of 50%, preferably of 20% to 23%, and, for connection to the incoming-air line, an essentially round connection piece (6) is provided, which opens centrally and axially into the outer pipe (2) and in which there is arranged, as means for creating the turbulent flow, a turbulence vane apparatus (10), a second end plate (3.2) preferably receiving this connection piece (6); in another embodiment, there is provided, for connection to the incoming-air line, an essentially rectangular connection piece which extends at least over almost the entire length of the outer pipe of the air passage, opens tangentially into the outer pipe and is attached tangentially, as means for creating the turbulent flow, to the outer pipe, both ends of the outer pipe preferably being assigned a central overflow opening. <IMAGE>
