Abstract
The climate change, its ramifications and the need to reduce greenhouse gas emissions are ever-present topics. The housing and residental sector contributes to these emissions with the use of fossil heating systems.
To contribute in the decarbonisation of the residental sector it is imperative to
further spread the usage of non-fossil systems which provide residental buildings with sustainable heating. With over 400.000 gas boiler systems installed in the city of Vienna alone there is great potential available.
However, current heat pump units and their peripherals are not well suited to
adequately substitute the fossil heating systems in small residental units due to
their size and range of power output. This is where the HYPERGRYD project and
this thesis want to make their contribution, with the aim to provide a heat pump
solution which can be easily retrofitted due to its modularity and the ability to
individually adapt the installed power output by the way of experimental methods.
Additionally, the usage of a novel latent heat storage system will be tested as a
way to enhance the heat storage capacity of the system as well as substitute the
previously necessary hot water tank for domestic hot water applications.
Several different operating points and operating configurations, with serial and
parallel operation at its heart, will be discussed in this thesis, to provide coverage on the to this date rarely treated topic. Furthermore, the performance of the modular heat pump system and its improvements compared to a single heat pump unit will be reviewed.
Finally, an optimistic outlook will be given as a conclusion, to emphasise the
importance of the findings - both for the present and the future.
