Core content and objectives:
Heat pumps are seen by most experts as one of the key technologies, but their market penetration is currently still very limited due to the difficulty of tapping sources in the area of high-density residential construction.
The aim of FitNeS is to develop modular split heat pumps with very compact façade-integrated outdoor units for use in residential heating and domestic hot water supply, whereby on the one hand a modular construction method with a high degree of prefabrication is to be made possible and on the other hand special consideration is to be given to architectural design and an attractive design. One of the main development goals is to minimise noise emissions through optimised air flow.
The best concepts for different outputs (e.g. 0.5 kW to 2.0 kW) are selected from a pre-selection of façade-integrated outdoor units (with different fan types/configurations and evaporator types/configurations) and developed and optimised in detail with computer support, as well as measured in the laboratory with regard to efficiency and noise emissions.
The aspects of building physics, efficiency and primary energy savings are examined and optimised using a holistic and systematic approach, whereby the evaluation of efficiency, comfort criteria, indoor air quality and acoustic aspects is carried out both through extensive laboratory tests and through dynamic building and system simulations with models validated by experiments. Finally, a functional model in a flat in a demo building is analysed with regard to efficiency and practical suitability (e.g. maintenance).
