Air velocity

The air throw, defined by CECOMAF- standard GT6-001 and ENV 328 as the distance between the fan and the point on the rotation axis where the outflow velocity reaches a limit of 0.25m/s, is used as the main criterion. However, it must be considered that in industrial application the velocity limit…

If the air velocity along the room is not enough to assure an optimal cold air distribution, the air stream will deflect and start looping. To avoid this effect you can: • increase the number of cooling units. • increase the rotational speed of the motor. • use long textile socks. All the proposed…

Plotted In red is the velocity of air of a standard unit, reached at different distances. As was expected, the velocity decreases with increased distance from the fan due to the mixing processes in the exhaust stream with other air in the room. It’s important to emphasise that the fan’s performance…

Graph 2 plots the results of unit INRW503K60W(B). Note that the limit velocity as ENV 328 rule (0.25m/s) is reached at 24 m without streamers. With streamers it is possible to increase the air throw to 11m; with the streamer the limit velocity was reached at 35m. When the limit velocity is…

Graph 3

Benefit of Streamers • Concentration of the outflow stream in axial direction. • Uniform and high efficient cooling of large rooms. • No energy losses • No fan efficiency performance disruption. • No noise • Easy installation 341
