The outdoor unit of the tabletop evaporators only consist of the condenser and the fans, the compressor is located in the interior. The challenge was to eliminate airborne noise in a high frequency range. Since the systems are on/off systems, they run continuously on the maximum air volume of 10,300 m3 / h.
Each unit each has the following dimensions: 2,006 x 956 x 1,268 mm L x W x H. The systems are mounted next to each other with a small gap.
The acoustic enclosure for the 2 systems has the dimensions: 2,006 x 956 x 1,268 mm (L x W x H). The hood was built to accommodate 2 table top evaporators and is 2,600 x 3,100 x 1,500 mm (L x W x H).
The sound reduction measured according to the enveloping surface method is 15 to 16 dB (A).
The acoustic hood is made entirely of aluminum. The basic construction is an aluminum plug-in system that is easy to assemble. Service doors were installed around the system, which allow unrestricted access to the system for service and maintenance work.
The inside of the acoustic hood is covered with 40 mm thick insulation (Stratocell Whisper).
The air inlet is guided at the bottom and blown out on the long sides at the top. An air short circuit is avoided by a transnorm sheet that separates the air chambers.
The sound hood was set up on our premises before shipping and we loaded it pre-assembled so that it can only be lifted over the system like a hat on site.
