Symbols and specifications
Q = Air Volume in m³/h
Ak = Effective surface (free area) of the neck of the diffuser in m²
Hm = Advised minimum - maximum mounting height in m
Bmin = Advised minimum distance between diffusers in m
Vk = Air velocity trough the neck of the diffuser in m/s
Ps = Static pressure loss in Pa
Lw(A) = Acoustic power in dB(A)
The values are given for isothermal supply air without Coanda effect.
The values in the table are given at an inclination angle α of the vanes of the diffuser set at 45°.
In order to achieve a high comfort level, the angle of the blades are automatically altered according to air supply temperature. The minimum and maximum angle of the blades can mechanically be limited. The ideal set angles can be determined in function of the temperature difference Δt between the supply air and room air temperature. (see selection graphs)
Acoustic powers below 20dB(A) are mentioned as "<20" in the tables.
