Abstract

Normally we protect ourselves from cross infection by supplying fresh air to a room by a diffuser, and this air is distributed in the room according to different principles such as: mixing ventilation, displacement ventilation, vertical ventilation, etc. Often this air distribution has the consequence that it is necessary to supply a very large amount of air to the whole room to obtain a sufficient dilution of the airborne infections.

When people are seated, a way to supply air direct to the breathing zone is to use "Personalized Ventilation". Personalized ventilation has shown to be very efficient in the protection of people from cross infection.

A personalized ventilation device has been developed in the form of a neck support pillow. The air is supplied to the free convection boundary layer of the person, and the layer then transports the air to the breathing zone. The velocities in this process are very small and draught may be able to disturb the process. Therefore, this research work deals with the effectiveness of the system with different levels and directions of draught.

The measurements are made with a full-scale manikin in a wind tunnel. The results show that the boundary layer and the process in the breathing zone are rather independent of draught at velocities up to 0.2 m/s.
