N2 - Problems with mould growth in dwellings usually occur in bedrooms in the microclimate behind closets placed next to exterior walls with poor insulation. It is anticipated that the problems are caused by lack of airflow behind the furniture in combination with a colder surface temperature and a high moisture production. The lack of air circulation decreases the surface temperature, which can cause problems. A particle image velocimetry (PIV) investigation was performed of the airflow patterns in such a microclimate. This paper describes the experimental set-up and the results. The results indicate that the flow rates behind the furniture will increase with increased distance between the closet and the wall, and even higher airflow rates are seen when the furniture is elevated by legs.
