ANALYSIS AND SIMULATION

 

Study and analysis are the basis of our projects

OneAir has always been committed to finding solutions in air distribution that best meet the various requirements in terms of comfort and obtaining the correct environmental parameters. For this purpose, we have developed in-house a dedicated software capable of simulating the behaviour of the air distribution line in order to analyse and verify any critical situations that may arise.

ONECFD simulation charts

Our ONECFD (Computational Flow Dynamics) software is able to meet the requirements of the UNI 10339 - EN 13182 standard and guarantee a high level of comfort for people in the rooms. The dimensioning of the geometry and size of the perforations is carried out on the basis of physical laws such as the conservation of momentum, mass and energy, and the equations that link the quantities of pressure and flow. The analysis of the air throw graphs makes it possible to verify the direction of the air flows within the environment and consequently to evaluate the best solution for air distribution. It is also possible to examine the residual velocities in the areas immediately adjacent to the diffuser and in the vicinity of the occupied zones in order to correct any criticalities.
