Air-2-Water Heat Pump Database
An acoustic database for air-to-water heatpumps has been established in Task 2. A paper describing the database and a first exploitation will be presented at the Forum Acusticum Euronoise 2025 Conference in June 2025.
63In the framework of IEA HPT Annex 63, an anonymous database has been designed that combines dimensions, operating conditions and a generic description of each of the 5 sides (fan(s), heat exchanger, blind sides) with their corresponding frequency spectrums. Initially, about 30 heat pumps measured at CETIAT and AIT are included in the database. The database will be enriched by the authors during the year 2025 with the possibility of contributions from other interested laboratories during this period.
The database can be downloaded here:
