Akustische Behandlung fĂĽr Klimaanlagen

Schallbarrieren

Barrera-O05BC2200051-cabecera

In Barcelona wird ein neues Gebäude errichtet. Auf dem Dach des Gebäudes sollen in einer speziellen Einhausung die Klimageräte und zwei Wärmerückgewinnungsanlagen installiert werden.

Der Schallleistungspegel der Klimageräte beträgt jeweils 87 dBA. Der Schallleistungspegel der Wärmerückgewinnungsgeräte beträgt jeweils 77 dBA.

Das Gebäude befindet sich in einer mäßig lärmempfindlichen Zone B2, der maximal zulässige nächtliche Lärmpegel beträgt 50 dBA.

Die Maschinen verfügen über einen geräuscharmen Betriebsmodus, der nachts eingestellt werden kann und den Emissionspegel um 9 dB reduziert.

Bei einer akustischen Untersuchung wurde festgestellt, dass die nachstehend aufgefĂĽhrten akustischen MaĂźnahmen erforderlich sind, um die Vorschriften zu erfĂĽllen.

Wie auf dem Foto zu sehen ist, wurden die Klimageräte 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 Lärmempfänger verbessert.

An der Wand mĂĽssen wegen der Positionierung der Klimageräte schallabsorbierende Akustikpaneele des Typs Acustison-50A angebracht werden.  Diese verhindern, dass der von den Maschinen erzeugte Lärm, der von dieser Oberfläche zurĂĽckgeworfen wird, die Isolierung der Schallbarriere durch indirekte Strahlung schwächt.

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 BelĂĽftung zu gewährleisten.

Aufgrund des begrenzten Platzes fĂĽr Wartungsarbeiten wurden so viele RS7C-SchallschutztĂĽren eingebaut wie möglich. So können die Bediener auf beiden Seiten der Maschinen arbeiten, ohne dass der Platz durch die Lärmschutzwand eingeschränkt wird.

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