5.2.3 Acoustic Dispersion with Heat Exchanger (RBS 2106)
The cabinet noise dispersion for an RBS 2106 with Heat Exchanger Climate Unit
is shown in the 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.
