5.2.4 Acoustic Dispersion with Heat Exchanger (RBS 2106i or
RBS 2106 V3)
The cabinet noise dispersion for an RBS 2106i or RBS 2106 V3 with Heat
Exchanger Climate Unit is shown in the figures and tables below. The figures
and tables show the noise dispersion generated by a free-standing cabinet and
by a cabinet mounted against a wall.
Note: The acoustic noise dispersion values for a free-standing cabinet
and a cabinet installed against a wall were tested according to
the ISO 9614-2 standard. Deviations from these values can be
experienced due to the nature of materials in the environment where
the cabinet is installed. Objects near the cabinet can reflect or absorb
sound and thus affect acoustic dispersion.
The following two tables show the sound pressure levels, calculated at the
bystander position at a distance of 1 metre from the cabinet and 1.5 metre
above the floor. The calculations are valid in free field. If the RBS is placed in a
room the sound pressure level will be higher than indicated in the tables below.
