Establish what building situation applies
Check the discharge height at which the system will be installed.
The necessary screening will depend on meteorological
and building-related factors. Examples of these are direct
and strong wind load, an entrance shielded by streets or
across the general wind direction etc.
Flow arising solely through temperature differences between
Where there is generally a low incoming flow, e.g. due to other
properties in front on the pressure side of the building with
incoming flow: between 1 and 3 m/s.
Where there is generally a strong incoming flow, e.g. position
on corners or market squares with little shelter from properties
in front: between 1 and 6 m/s. Considerably more in completely
exposed areas out in the open.
Door surfaces are on one side of the building. No notable possibilities to discharge air through thermal or chimney effect.
Air roll rotating inwards.
Door surfaces are on one side of the building. Possibilities to discharge air into upper floors through thermal effect or outside through chimney effect
LAir roll rotating outwards.
Unscreened door surfaces are also on other sides of buildings, e.g. at the side or opposite. The air discharge potential is identical to or greater than the size of the door surface to be screened.
Air curtain systems make considerable contributions to reducing energy costs - up to 80 % with the Teddington CONVERGO® system.
Visitors to a shop that is at the right temperature demonstrate far greater willingness to spend time and money there.
Ultimately the saving also reduces energy consumption, which is good for the environment.
For example, sealing off unpleasant smells or dust development in industry. In addition, a good indoor climate reduces the incidence of staff sickness.
