In the pictures above is an example of simulation CFD (computational fluid dynamics simulation software) that

allows to simulate the airflow in the room check both speed (Fig. 8) and temperatures (Fig. 7). In this case the

duct is installed at an elevated high (8.5 m) and objective of the simulation is to verify that the supply air is able

to reach the floor while ensuring compliance with the speed of 0.2 m / s at head height. As for speed, fig. 8,

isokinetic different areas are represented with color scale that goes from red (higher speed of 0.2 m/s) to blue

(zero speed). As regards the temperature, Fig. 7, different areas are represented by isothermal chromatic scale

that goes from red (higher temperature of 26 °C) to blue (below 25 °C).
