Heat Pump Acoustics

Description

Invited Lecture on "Heat Pump Acoustics" in the framework of the PhD Seminar, December, 6th, at the Division of Applied Thermodynamics in the Department of Energy Technology

Reduction of acoustic emissions is important to further increase the acceptance of all type of heat pumps. Especially the deployment of air-to-water units can have negative effects to both the owner and the neighbours depending on the acoustic & vibration characteristics of the unit itself, its installation and placement. To increase the acceptance by minimizing noise annoyance and thus removing a possible market barrier, focus has to be put on understanding the acoustics emissions at steady state and the transient behaviour of acoustic signatures during different operating conditions (e.g. icing, de- frosting, capacity control, cooling mode). Through its Heat Pump Technology Collaboration platform, the International Energy Agency is pursuing research and networking activities on heat pump acoustics in two Annexes, which will also be introduced during the presentation.
