<p>An air distribution plant comprising a channelling (2) through which an air flow is transferred by a device destined to transmit energy to the air flow via an increase in pressure to a use zone, the channelling (2) comprising at least a transfer conduit (3) placed in fluid communication with the ventilator and at least a diffuser conduit (4) placed in fluid communication with the transfer conduit (3) and provided with a plurality of diffuser holes (8) arranged on at least an external wall thereof in order to inject air into the use zone. The channelling (2) comprises at least an access (9) having larger dimensions than dimensions of each diffuser hole (8) afforded on an external wall (10) of the channelling (2) A discharge trap door (101) is mounted at the access (9) and is mobile among a plurality of stable positions comprised between a closed position of the access (9) and a position of maximum opening of the access (9). The discharge trap door has the function of discharging a part of the delivery air directly into the environment to be treated, thus reducing the outflow velocity from the holes, and then inducing the air such as to regulate an intensity of the air draughts created at ground level.</p> |
