Special acoustic enclosure for a Viessmann VITOCAL air/water heat pump installed on wall brackets4/6/2023 Acoustic enclosure custom-made for a Viessman VITOCAL 100-A air-to-water heat pump (BARDOLINO site on Lake Garda).
Initial situation A Viessmann "VITOCAL 100-A" heat pump was to be equipped with an acoustic hood. The Heat Pump has the following dimensions: 1'044 x 456 x 1'404 mm L x W x H. The plant has 2 axial fans with a maximum flow rate at full load of 4'500 m3/h. Special The unit is mounted to the house wall with brackets with a floor distance of 780 mm. Acoustic enclosure concept The basic structure of the acoustic hood is based on an aluminum plug-in system with 2 modules, (1 basic module under the console + add-on module) in whose profile frame the service doors are integrated around the unit. The service doors are based on 1.5 mm thick aluminum panels with 40 mm thick Stratocell® Whisper insulation, one of the best sound absorbing materials available on the market. The sunderstructure module of the sound enclosure can be used as a storage space. The enclosure d has the following dimensions: 1'800 x 1'200 2'300 mm (L x W x H) with a weight of 191 kg. The free air openings are designed with about 15% above the required air volume of the system. The airflow is laterally offset so that no air short-circuit can occur between the exhaust and supply air. The 90° air deflection breaks up the airborne noise, resulting in a significant reduction of the outlet noise. Noise reduction The all-round noise reduction over the frequency spectrum from 63 to 8,000 Hz is between 17 and 20 dB(A), with a pressure loss of around 15 Pascal. www.silent-mode.com
