Sound insulation of hydraulic lines
Heat pumps generate vibrations and structure-borne
noise. If installation is not carried out correctly, these
vibrations/noises can even be transmitted via the pipe-
work to rooms located some distance away.
Spring-mounted compressors substantially reduce the
transfer of vibrations to the floor. The anti-vibration
bases described in chapter "Requirements for heat
pump siting" are another structural measure for chal-
lenging applications.
The transfer of "airborne noise" is reduced to such an
extent by a sound-insulating casing that values below
58 dB are achieved.
The hydraulic lines can transfer shocks and vibrations
to walls.
The obvious solution here is sound insulation with rub-
ber expansion joints:
■
Basic sound insulation with one rubber expansion
joint per connection for the standard application
(installation in connection direction)
■
Optimised sound insulation with two rubber expan-
sion joints per connection for challenging applica-
tions (with on-site 90° bend)

Note
If adaptors are used, expansion joints must always be
installed to compensate for vibrations.
For sound insulation without rubber expansion joints,
an on-site solution must be provided.
Fastening of pipes to the wall/floor
Standard rubber pipe clamps only dampen flow noises.
Rubber-mounted base plates reduce the transfer of
low-frequency vibrations and structure-borne noise to
a minimum.
Note
Do not secure the lines between the expansion joints
and the heat pump!
