The fundamental task of the ventilation systems based on the fabric ducts is the even inflow of fresh – treated air that provides keeping the set temperature in the room. Their additional feature is to provide the air interchangeability while meeting the strict hygiene standards. The fact also important is that application of the fabric ducts provides eliminating the draught phenomenon in the people stay zone. As the air supply is done on the whole surface of the duct, we obtain in consequence the low level of the supply air stream speed – below 0,1 m/s.
Simultaneously, the fabric ducts are favourable solution as for keeping the even distribution of the supply air. As contrasted with the traditional ventilators that work only close to one another, the fabric ducts enable to eliminate the adverse effect of elements impeding the flow of air stream – such as pillars, frames, racks, etc.
