The profiles of the air temperature difference with
displacement ventilation shown in Fig. 9 point out that the
colder supply air warmed up a bit along its way to axis 3
being both convectively heated by the warmer floor and partly mixed with the warmer room air. The comparison of
the different air temperature profiles above 1.0 m height
shows almost uniform air temperatures in the part of the
room under the cooled ceiling and rising temperatures at
the axes 1 and 2. The vertical air temperature rise measured
at axes 1 and 2 for this variation corresponds to
about 15% dissatisfied occupants compare Fig. 4 and Ž .
approaches the limit for thermal comfort.
