They are new metal ducts, with circular or semicircular section.
They exploit the specific air-conditioned distribution and diffusion system called high induction.
The High induction is created by the air flow passing through small and average size holes, which are made along the whole duct, in order to mix optimally the primary air with the one present in the room, reaching in this way an high comfort in the room.

The specific Induction METAL JET diffusion system exploit the possibility to distribute the treated air, succeeding to guarantee an high exchange and mixing surface with the room-air, which is livened up by friction and by consequence of depressions and whirls that are put in motion by air mixing itself. This phenomenon is due to the preservation of motion quantity principle: Qin x ρ x Vin= COST = K.
Thanks to a specific initial impulse, this inductive effect allows to liven up an air amount greater than the one put into the room, reaching values even 50 times the primary air flow-rate put into the room, according to the diameter and the geometry of the holes and to the static pressure.
KLIMAGIEL has implemented a CFD (Computational Fluid Dynamics) program, which allows to simulate precisely the air flow through the processing of the ther- modynamic and geometrical parameters of the system given by the Customer. In this way it is possible to evaluate realistically the temperatures and air velo- cities in every point of the room even on the planning stage.
The picture shows as the entire air mass present in the room is livened up with a speed lower than 0,15 m/sec at 1,5 m from the floor.
The micrometric control of the output air flow velocity (“high induction” effect), all around the duct surface, prevents the moisture stagnation and the resulting condensation development.
The perfect calibration and position of the holes, together with the meticulous air velocity control, allows to reach a room quietness suitable for each kind of installation.
Klimagiel system uses a small number of assembling components, thus making the installation very easy and fast.
