embedded in plaster , as other installations, e.g., lights or .
construction components, take up some space. In order to
be able to investigate the impact of a partly-cooled ceiling
on the airflow pattern, the air quality and thermal comfort,
the total area of the cooled ceiling was divided into two
equally sized parts with individual cold water cycles. Due
to this, the cold water flow through each of these cooling
areas could be controlled individually and either the entire
cooled ceiling or just one half of it was cooled.
Additionally, the heat sources in the test chamber were
arranged in three different configurations, so that several
