VOLKSWAGEN SHOWROOM – DESTRATIFICATION FAN SYSTEM
Under normal winter heating conditions the temperature in the Volkswagen showroom at high level was measured at 32
This stratification effect can be seen in this illustration and is very common in buildings of this nature.
In December of 2008 two Airius model 25 destratification fans were installed. These gave a much more comfortable even temperature throughout the area.
Following installation it was also noted that the heating, which normally ran all day trying to reach it’s set temperature, would switch off by midday and not start again until after 4pm.
