Akustische Behandlung fĂŒr Klimaanlagen

Schallbarrieren

Barrera-O05BC2200051-cabecera

In Barcelona wird ein neues GebĂ€ude errichtet. Auf dem Dach des GebĂ€udes sollen in einer speziellen Einhausung die KlimagerĂ€te und zwei WĂ€rmerĂŒckgewinnungsanlagen installiert werden.

Der Schallleistungspegel der KlimagerĂ€te betrĂ€gt jeweils 87 dBA. Der Schallleistungspegel der WĂ€rmerĂŒckgewinnungsgerĂ€te betrĂ€gt jeweils 77 dBA.

Das GebĂ€ude befindet sich in einer mĂ€ĂŸig lĂ€rmempfindlichen Zone B2, der maximal zulĂ€ssige nĂ€chtliche LĂ€rmpegel betrĂ€gt 50 dBA.

Die Maschinen verfĂŒgen ĂŒber einen gerĂ€uscharmen Betriebsmodus, der nachts eingestellt werden kann und den Emissionspegel um 9 dB reduziert.

Bei einer akustischen Untersuchung wurde festgestellt, dass die nachstehend aufgefĂŒhrten akustischen Maßnahmen erforderlich sind, um die Vorschriften zu erfĂŒllen.

Wie auf dem Foto zu sehen ist, wurden die KlimagerÀte sehr nahe an der Wand der Einhausung platziert. Durch diese Positionierung werden die Maschinen von der Immobiliengrenze entfernt, wodurch sich die Situation in Bezug auf potenzielle LÀrmempfÀnger verbessert.

An der Wand mĂŒssen wegen der Positionierung der KlimagerĂ€te schallabsorbierende Akustikpaneele des Typs Acustison-50A angebracht werden.  Diese verhindern, dass der von den Maschinen erzeugte LĂ€rm, der von dieser OberflĂ€che zurĂŒckgeworfen wird, die Isolierung der Schallbarriere durch indirekte Strahlung schwĂ€cht.

Man kann gut erkennen, dass die Barriere nicht bis zum Boden reicht. Aufgrund des geringen Abstands der AcustimĂłdul-80A Paneele, welche die Barriere bilden, muss die Maschine mit Luft versorgt werden, damit sie richtig funktioniert. Daher dient der untere, offene Teil der Barriere dazu, die notwendige BelĂŒftung zu gewĂ€hrleisten.

Aufgrund des begrenzten Platzes fĂŒr Wartungsarbeiten wurden so viele RS7C-SchallschutztĂŒren eingebaut wie möglich. So können die Bediener auf beiden Seiten der Maschinen arbeiten, ohne dass der Platz durch die LĂ€rmschutzwand eingeschrĂ€nkt wird.

Bei den ĂŒbrigen Maschinen, die entlang der anderen Fassade installiert wurden, wurde derselbe Ansatz verfolgt; der Aufbau ist auf den folgenden Fotos zu sehen.
