Soundlevel
31 Soundlevel
Noise levels must be taken into consideration when siting the system.
In accordance with TA-Lärm [or local regulations], the following emission limits must be observed:
Area Noise emission limits

Day
06:00 - 22:00
Night
22:00 - 06:00
Spa complexes, hospitals and care homes, where indicated as such by means of
signs on the premises or road.

(generallyresidentialareas)

Emission location neither primarily surrounded by commercial facilities nor by
residential buildings(coreareas,mixedareas)
60 45
Emission location surrounded primarily by commercial facilities(commercialareas) 65 50
Emission location surrounded exclusively by commercial facilities and perhaps the
occasional residential building for the owners and managers of the facilities and for
supervisors and on-call staff(industrialareas)

Measuring location outside but close to the residence concerned (0.5 m in front of the open window that is most affected)
31.1 Thefollowingmustbeobservedwheninstallingthesystem
Avoid siting the heat pump directly outside or below windows of noise-sensitive rooms, e.g. bedrooms.
Installation in recesses or between 2 walls is not recommended, as this will increase the noise level due to sound
reection.
The sound power level of heat pumps is calculated in accordance with EN 12102. It enables comparisons to be
made independently of surroundings, direction and distance.
31.2 Soundreection(directivityQ)
With the number of adjacent vertical surfaces (for example walls), the sound pressure level increases exponentially
tothefreepositioning(Q=directivity).
