Symbols and specifications
Q = Air volume in m³/h
Ak = Effective surface (free area) in m²
B = Distance between the diffusers in m
H = Installation height of the diffusers in m
Vz = Maximum velocity at the occupied zone according to distance between the diffusers and installation height in m/s
Vk = Average effective velocity through the diffuser in m/s
X0.25 = Throw length in m at an end velocity Vt of 0,25m/s
Pt = Total pressure loss over difuuser and plenum given in Pa
Lw(A) = Acoustic power in dB(A)
The throw X0.25 is given at an end velocity of 0.25m/s for a smooth ceiling without any obstacles.
The values are given for isothermal supply air. Throw distances for cooling conditions at -11K can be calculated by dividing the X0.25 values with factor 1.1. For heating purposes at Dt of +11K a multiplier of 1.1 should be applied to the given X0.25 value.
In order to achieve a high comfort level, selections can be made according to the maximal velocity at the occupied zone Vz. These values are given at distances between diffusers B and installation heights H. Velocities Vz lower than, or equal to 0,25m/s at the occupied zone are advised.
The pressure losses Ps are given for diffusers without damper of with fully opened damper.
The acoustic power values Lw(A) are given for diffusers without damper of with fully opened damper without room attenuation. Acoustic powers below 20dB(A) are mentioned as "<20" in the tables.
