Abstract

The invention relates to a method in which the dominative drop in pressure of a flow stabilised ventilation system is established across the supply air terminal devices of respective rooms. By using supply air terminal devices that include several nozzles of noise minimising construction and numbers for leading air into the room, it is possible to allow a drop in pressure of up to 250 pascal across the device without exceeding office noise limits. The invention obviates the need for throttles, constrictions and sound dampening means. Because the dominative drop in pressure is established across the supply air terminal device, and because said device is a nozzle-type device, there will be relatively little change in the airflow through the sytem conduits and through the supply air terminal devices as a result of pressure changes in the system.
