If use blower fan dispatch wind, it is the problem that can solve room air circulation, exchange.But blower fan can produce extra noise, also can produce the maintenance expense of extra energy consumption and blower fan.
Labyrinth silencer also claims cell-type sound absorber, by several cell-type sound absorbers formation labyrinth silencer that is together in series.This sound absorber is except having resistive effect, the expansion by cell section with dwindle, also there is resistance effect, therefore, be characterized in anechoic frequency bandwidth, sound deadening capacity is higher, but that resistance is damaged is larger, is applicable to low wind friction velocity, wind speed υ is unsuitable >=5m/s.
The aerodynamic quality of sound absorber is to evaluate another important indicator of acoustic attenuation performance, and it has reflected the size of sound absorber to gas-flow resistance.The aerodynamic quality of sound absorber represents with resistance coefficient or drag losses.Drag losses, is called for short resistance and damages, and refers to when air-flow passes through sound absorber the numerical value reducing than entrance point at the hydrostatic pressure of the sound absorber port of export.
The loss of total pressure △ P of sound absorber, comprises along stroke pressure loss △ Pm and local pressure loss and calculates △ Pj,
△P=△Pm+△Pj(Pa) △Pm = λ/de×υ2/2×ρ △Pj= ξυ2/2×ρ(Pa)，
△P=λ/de×υ2/2×ρ+ξυ2/2×ρ=(λ/de+ξ)υ2/2×ρ
In formula: the Δ P--pressure loss, Pa;
λ--coefficient of frictional resistance;
The effective silencing channel equivalent diameter of de--sound absorber de=2ab/a+b
υ--wind speed (m/s)
ξ--coefficient of partial resistance
ρ--atmospheric density (generally getting 1.2kg/m3)
Obviously, the resistance of sound absorber damage size is to have directly related with the air velocity size under service condition.When air velocity υ≤0.30m/s, gross pressure pressure loss Δ P≤0.054 of sound absorber (λ/de+ ξ) (Pa)
