LoginDue to the fact that more and more people are spending a considerable amount of time in an indoor environment it is important to minimise (or control) the amount of pollution that a person is exposed to. Sources of indoor air pollution are building materials, furniture, equipment and people. This work concentrates on personal exposure in a mixing ventilated room. The aim of this work is to investigate the exposure of a person due to pollution from another person in a mixing ventilated room. The investigation involves full-scale experiments in which two breathing thermal manikins (BRM) have been used. In general it is found that the amount of exposure from another person was limited and shown to be independent of the location of the persons. It is concluded that mixing ventilation is an effective ventilation principle to minimise the personal exposure to pollution from other persons. It is also shown that the human boundary layer is of significant importance to provide clean air to a person's breathing zone.
