PRODUCT DESCRIPTION
The displacement flow units types QLE and QLF are primarily employed in comfort
conditioning. As opposed to the familiar principle of mixed air flow through ceiling or wall
diffusers, displacement flow units guarantee low-turbulence air supply. The discharge
velocity is very low.
Depending on the degree of activity of the persons in the occupied zone, the supply air
can enter the space with a temperature difference of -1K to -6K in relation to the room air.
The air spreads out on the floor and is lifted up by convection currents from heat sources
(machines, electrical equipment, people, etc.). The fresh air, therefore, finds its own path
to the heat source from which the heat load must be removed. With an even distribution
of displacement flow diffusers, even large halls (e. g. auditoria, industrial factories) can
be air-conditioned without draughts in an economical manner.
