Summary

Natural refrigerants are becoming increasingly crucial concerning the increasing relevance of heat pumps as a climate- and resource-friendly option for heating and considering the political measures to phase down refrigerants with high global warming potential (GWP). In particular, using R-290 in residential heat pumps is becoming increasingly essential due to its low environmental impact (GWP100 = 3) and favorable thermodynamic properties. In addition to the potential of using this refrigerant, it poses challenges regarding the system design, safety measures, and especially the compressor design, which must be considered. This study focuses on methods and approaches for identifying and investigating challenges when using R-290 as a refrigerant in residential heat pumps. In addition to looking at the system as a whole, the importance of the compressor for this refrigerant is examined. This study aims to identify and analyze possible challenges for the compressor and the system in general and present investigation methods. This includes considering the degradation phenomena of compressors operated in heat pumps and identifying potential causes.
