OneAir diffuser ducts

 

Integrated solutions for the comfort

The OneAir diffusers, through their inductive diffusion, allow an optimal distribution of the air in small or large environments for all types of use such as ventilation, heating, air conditioning and refrigeration.

This type of diffusion, produced by means of a calibrated perforation made with ONELASER technology, allows to trigger displacements of large quantities of ambient air, avoiding stratification phenomena and ensuring a high environmental comfort for people in civil and industrial environments.

According to the peculiarities of each system and the specific needs of customers, different materials are available: DHI METAL, DHI TEXTILE and DHI PLASTIC.

To offer efficient solutions adaptable to any environment, the OneAir diffusion ducts can be produced in different forms: circular, semicircular and quarter-circle.

To complete the proposed products, OneAir also offers a plurality of systems designed to facilitate and improve certain installation situations and operating problems.

The service offered by OneAir provides:

➤ Customized design and sizing for each project

➤ The ducts packaged in the required shapes and sizes complete with assembly instructions

➤ The fixing system

 

Functioning principle

 

The design and construction of OneAir ducts exploits the principle of high induction. What is it about?

The operation is like a turbulent movement to all effects. The original idea is to take advantage in a suitable way of the lamination of a fluid vein, which by calculated speeds creates points of low pressure, which activate the mixing of the inlet air with the existing air in the room by short and permanent paths, returning a high efficiency of the system.

The fluid vein that comes out at high speed takes on the characteristic of a contracted vein due to the higher speed that is recorded in the center of the nozzle with respect to the edges, and this causes a depression such as to recall the surrounding ambient air and bring it to mixing in the jet resulting.

Therefore, in short, the speed of the outgoing air in each individual nozzle forces the mass of air to move with progressively decreasing speeds so as to have optimal mixing in the area concerned with extremely low residual speeds and therefore high system efficiency. This is why we at OneAir are tireless in seeking the best compromise between speed, pressure, materials etc. which allow the highest level of final comfort which means, for example, the de-stratification of hot air in winter with consequent savings also in economic terms or the silence of the air diffusion both in heating and cooling mode.

Induction ratio (system efficiency) = Flow air rate Q * K (K value between 20 and 40)

this means that on average

the moved air quantity is 30 times the inlet air quantity
