The principles of air diffusion

BEAM: 100% porous diffusion

This type of air diffusion works using permeable textile materials. The very large or even total exchange surface ensures rapid deceleration of the blown-in air masses and practically zero diffusion energy (0.01 to 0.2 m/s) despite the high flow rate.

This principle is ideal for applications with air change rates in excess of 20 V/H.

→ Diffusion principle: Laminar flow
→ Air ejection velocity: 0.01 to 0.2m/s
→ Air throw : Nil
→ Installation height: < 3 m
→ Air treatment mode: Isothermal – cooling

RADIANT: Diffusion through porous strips

This diffusion principle is based on the permeability of the fabric. It allows air to be blown through the duct fabric at very low ejection velocities (0.1 to 0.8 m/s). Depending on the air ranges, air will be directed through porous strips. Air will diffuse by displacement due to the difference in weight between the warm and cold air masses. . It is ideal for applications with high mixing rates (ISO class, clean rooms, laboratories) and comfort (processes, people, sensitive products). This type of diffusion is suitable for controlled environment rooms with personnel.

→ Diffusion principle: Air displacement
→ Air ejection velocity: 0.2 to 1 m/s
→ Air throw : 0.5 m to 3m
→ Installation height: < < 4 m
→ Air treatment mode: Isothermal – cooling – refrigeration

IMPULSION: Diffusion through woven wire strips

The ducts are fitted with woven wire strips placed along their length. Increasing the diffusion mesh increases ejection velocities and air ranges. The orientation of these slots allows linear and directed air displacements, enabling aeraulic effects to be obtained (Coanda, air curtain). This type of diffusion is suitable for temperate premises.

→ Diffusion principle: Air gap
→ Air ejection velocity: 1 m/s to 5 m/s
→ Air throw : 3 m to 6 m
→ Installation height: < < 5 m
→ Air treatment mode: Isothermal – Cooling – Heating compensation

ENERGIE S: Diffusion through small perforation

The design of micro-perforated diffusers is based on the displacement of air mass. This principle is known as induction. The air is ejected through a large number of small-diameter perforations, positioned over a large part of the circumference of the duct (up to 180°). These models, with very high induction, cause significant air mixing, enabling uniform temperature treatment with small or medium air ranges (1 to 4 m).

→ Diffusion principle: High air induction
→ Air ejection velocity: 10 to 15 m/s
→ Air throw : 1 m to 4 m
→ Installation height: < < 4 m
→ Air treatment mode: Cooling – Reversible air conditioning – Heating

ENERGIE M: Diffusion through medium perforation

The design of micro-perforated diffusers is based on the displacement of air mass. This principle is known as induction. Air is ejected through perforations which are positioned either in strips. These models, with very high induction, cause significant air movement thanks to large air ranges (3 to 10 m) without generating a sensation of air in occupied areas.

→ Diffusion principle: Air induction
→ Air ejection velocity: 12 m/s to 17 m/s
→ Air throw : 4 m to 12 m
→ Installation height: 4 to 12 m
→ Air treatment mode: Cooling – Reversible air conditioning – Heating

ENREGIE L: Diffusion through large perforation

To avoid stratification problems in in high-ceiling spaces (8 to 20 m), the ducts are perforated with large or very large perforations (15 to 30 mm). These orifices act like distribution nozzles, moving large quantities of air through a powerful jet of air. This type of diffusion is suitable for large volumes and high ceilings.

→ Diffusion principle: Long range
→ Air ejection velocity: 13 m/s to 30 m/s
→ Air throw : 8 m to 15 m
→ Installation height: 7 to 20 m
→ Air treatment mode: Cooling – Reversible air conditioning – Heating
