With the adoption and implementation of the Kigali Amendment in China
the R134a refrigerant has gradually reduced and could be eliminated in China′s mobile air conditioning (MAC). Currently
the most important alternative refrigerants for MAC are R1234yf
CO
2
and R290; however
China has no criteria for the selection of these three refrigerants. Recently
Germany and five other countries have proposed regulations to restrict PFASs
and R1234yf has also been included in the restricted list; therefore
the prospect of R1234yf is not optimistic. In this context
this study compares R1234yf
CO
2
and R290 in terms of environmental protection
safety
economy
and system performance. Relevant research results and conclusions are summarized
and the latest PFAS substance restriction proposal involving MAC was organized and analyzed. These efforts provide direction for the research of alternative refrigerants in the field of MAC in China
which may be used as a basis for the selection of alternative refrigerants for MAC in the future.
