Compact Noise Control Solution for Air Heat Pump in an Apartment
Project Overview
Viklicky Kälte-und Klimatechnik, an innovative gas-water heating installation company, aimed to install an air heat pump in a compact 50m² apartment on the 7th floor of a residential building.
The challenge was to minimise space consumption while meeting strict noise level requirements.
Challenge
In this small apartment, the objective was to install an air heat pump and boiler while ensuring noise levels remained below 35 dB(A) both inside and outside the apartment. Space optimisation was crucial to maintain living comfort.
Scope of Work
- Enclosure of the heat pump and the boiler with highly absorbent acoustic foam and veneered wood panels to create a visual border
- Installation of the heat pump on custom anti-vibration pads to reduce structure-borne noise
- Implementation of sound absorbers for effective noise reduction without impeding the heat pump's air intake
Solution
To address the unique acoustic and spatial demands of the apartment, our solution focused on combining efficiency with discretion. The heat pump and boiler were enclosed in a compact housing lined with sound-absorbing foam and finished with veneered wood, offering both acoustic insulation and a clean, integrated appearance.
Anti-vibration pads were used to decouple the unit from the building structure, reducing transmission of mechanical noise. Additionally, sound absorbers were carefully positioned to lower airborne noise levels while preserving unobstructed airflow for optimal system performance.
The products we used were:
Result
The noise levels were successfully reduced, achieving levels 3-4 dB(A) below the target (35 dB(A)) in the room and on the balcony. The compact housing design allowed maximum living space for the residents while ensuring the efficient operation of the air heat pump.
This project highlights the effectiveness of combining acoustic materials and expertise to address noise challenges while optimising space utilisation. Our solutions not only meet strict noise level requirements but also enhance living comfort.
Noise in Residential Spaces
As residential buildings increasingly adopt energy-efficient HVAC systems like air heat pumps, managing noise within confined spaces becomes essential. In compact apartments, even moderate noise can impact quality of life.
DECIBEL’s work on this project demonstrates how integrated acoustic solutions, combining materials, vibration control, and smart design, can meet strict sound regulations without sacrificing comfort or functionality.
This approach sets a benchmark for sustainable, low-noise residential installations in urban environments.
