dBEL.HVAC: Visualized Noise Predictions for Heat Pump Distribution in a Few Clicks.
Our cloud application dBEL.HVAC allows sales representatives and heating installers to quickly and easily generate reliable forecasts of noise pollution near a planned heat pump – and present the results to customers in a clear and convincing way.
Making 'Quiet' Visible.
HVAC systems in general and heat pumps in particular have a reputation for being noise polluters. And indeed, they are always accompanied by some level of noise emission. However, they typically only cause disturbing noise when poorly planned.
How can you avoid noise disturbance for neighbors or homeowners, and how can potential customers be convinced of this? We have developed a cloud application called dBEL.HVAC to assist you:

How can you avoid noise disturbance for neighbors or homeowners, and how can potential customers be convinced of this? We have developed a cloud application called dBEL.HVAC to assist you:
Step 1: Operate the heat pump as quietly as possible
One important factor is, of course, the device itself. However, the positioning also has a significant impact. With dBEL.HVAC, you can examine your individual product range directly in the planned environment using "ready-to-use" geomodels and thus find the ideal installation location.

Step 2: Convince customers that the heat pump will not cause noise issues
A dBEL noise map speaks volumes – and delivers on its promises through profound noise prediction based on calculation methods from professional planning. This visually demonstrates how quiet your heat pump truly is, turning the acoustic issue into a selling point.

Forecast certainty through normatively validated calculation methods. Without a manual and within minutes.
dBEL.HVAC works with calculation methods from specialist planning that allow very detailed and professionally verified noise prediction. The basis for this is...
- Ready-to-use geomodels that provide all necessary information about the environment (e.g., geometric distances, shielding, and reflections) and
- High-quality sound-emitting 3D models of your heat pumps – this ensures that the calculation takes into account the specific radiation pattern (directivity) as well as self-shielding (e.g., for cascades of multiple units).
The expertise required for meaningful and reliable forecasts is directly integrated into the tool and can be accessed by the user – for example, the sales team – with just a few clicks and without a manual.
The calculation is thus not based on simplifications and assumptions, but on the actual and individual framework conditions of the specific project. Therefore, significantly less margin needs to be factored in – giving you more planning flexibility for the installation.

Whether integrated into an online configurator, as a password-protected web account, or as a freely accessible web widget on your website – you decide how and for whom our technology should be made accessible.
Background: Noise generation from heat pumps and why detailed sound propagation calculations are important
Heat pumps make noise – they can be quiet, but never completely silent. This is due, among other factors, to the following components, characteristics, and conditions:
Fan: When the fan blades move, flow and pressure fluctuations can occur, generating pressure impulses and thus causing noise. These noises can vary depending on the heat pump's speed.
Compressor: When the compressor is operated with alternating current, individual tones with the mains frequency of 50 Hz and integer multiples thereof may occur.
Directivity: Since a heat pump is not an omnidirectional sound source, more radiation occurs in certain directions than in others. This is especially the case with flow noises from the fan.
Reflections: The operating noise level can be locally increased by sound reflections, especially from largely acoustically hard building facades or ground surfaces.
The mentioned factors depend on the device and the installation location – and are therefore different in every project. To achieve reliable forecasts, it is necessary to include them in the calculation as realistically as possible.
More efficient cooperation with specialist planners when approving large heat pumps.
For a long time, large heat pumps were mainly used in industry. However, they are increasingly being deployed closer to residential areas as part of district heating systems – making noise pollution an increasingly pressing issue.
They are generally subject to approval, which means that an individual noise report is drawn up in each case. While dBEL.HVAC cannot replace this assessment, its ability to quickly and easily check numerous variants, especially in the early planning phases such as feasibility studies and site evaluations, can save costs and time.
