Acoustic Enclosure for carrier chiller - food undustry

The picture shows a acoustic enclosure for a Carrier refrigeration system with four axial fans with vertical air flow and an air volume of 28,900 m3/h at the highest performance level.

The system is used to cool the production rooms of a food manufacturer and is in the immediate vicinity of a residential area. Noise complaints from residents led to the system being fitted with a sound barrier.

The acoustic hood offers the following advantages:
Noise reduction over the entire frequency band of -19 dB (A) so that the system also fulfills the maximum permitted sound level for residential areas of 35 dB (A) in the evening and after hours at the next immission location (nearest window to the system). #

The acoustic hood is made entirely of aluminum and powder-coated in RAL color 9006.

Infrared refrigerant sensors with a detection limit of ≤ 10 ppm, which are built into the hood, warn the operator of even the slightest loss of refrigerant. The sound enclosure was delivered to the construction site pre-assembled in 4 parts and set up on the additional concrete foundation built around the system in less than 2 hours.
