Beschreibung

Heat pumps are a versatile enery efficient and renewable energy technology with vast potential in contributing substantially to the required changes in the energy system. Especially air-based heat pump systems can play an important role in densely populated, urban areas due to their multiple advantages such as low space requirement or simple installation. The compressor and fans of air-sourced heat pumps often emit acoustic emissions which are reinforced in the transition period as a result of the icing of the evaporator. The operating noise of heat pumps can cause conflicts in neighbourhoods leading to health, psychological and financial problems. This may become a serious disadvantiage for the heat pump technology and may hamper its broad market penetration. IEA HPT Annex 51 primarily aims at improving the acceptance of heat pumps and removing market barriers by reducing acoustic noise emissions and vibrations. The project came to a close in December 2021. Within the framework of the IEA HPT Annex 51, a large number of freely available detailed documents were produced by the international and national working group, which are described in this contribution. Furthermore, the recording of a webinar as an introduction to the topics is available for download on the website of the international IEA HPT Annex 51. Currently, a follow up is designed, which will specifically focus on the placement impact on heat pump acoustics.
