Electrically driven heat pumps and refrigeration systems are a future technology of the energy transformation. For widespread use in multi-family dwellings or office buildings, a new generation of equipment is required which, in addition to high energy efficiency, also produces low noise emissions.

The "WAMS" project addresses the further development and evaluation of complex supply systems for heating, air conditioning and ventilation, as well as domestic water heating, primarily in the residential building segment. The overall objective is to reduce barriers to market entry by further developing and applying new methods and procedures for evaluating and optimizing the above-mentioned systems. Part of this project is particularly aimed at reducing noise emissions and thus potential noise pollution. A second part of the project focuses on the establishment of transparency regarding the performance of complex hybrid/multivalent systems as well as a faster and more cost-effective evaluation of innovative complex systems.
