Ventilation systems utilizing the displacement principie had their breakthrough in the Nordic countries during the 1980s. In new office buildings these systems have a market share today of about 25%. What often has been neglected is to pay attention to the disadvantages which the system entails. This, however, is rather natural since research into the limitations of the systems has hitherto been neglected.
Every new ventilation system introduced on the market first has to be very carefully analyzed regarding advantages as well as disadvantages. The limitations of the system have to be very clearly indicated. When discussing the function of the displacement ventilation system, there are three different parameters of interest:
This paper discusses the current state of displacement systems with regard to these parameters. The trends in development of the systems are discussed. A bright future is predicted for this technique of supplying air at low velocity.
