Due to installation effects, heat exchangers can increase the sound radiation of axial fans in heat pump applications. The increase in rotor noise is due to the disturbed flow field induced by the heat exchanger. In particular, the diameter of the coolant tube and the geometry of the heat exchanger have a major influence on the resulting sound radiation of the axial fan. Inhomogeneities in the flow field caused by the geometry of the heat exchanger housing have a significant influence on the tonal components in the fan's sound pressure spectrum. As the turbulence level increases, the broadband sound radiation of the fan increases due to the amplification of the leading edge sound sources. The tonalities in the radiated sound field and the total sound pressure level could be reduced in the future by appropriate selection of the heat exchanger parameters. This will allow the installation of quieter heat pumps in residential areas and thus increase the acceptance of the units by the public.
