Abstract

Currently,the refrigerant of automotive air-conditioner is mainly R134a.Due to requirements of environmental protection,the replacement of automotive refrigerant gradually put on the agenda.Now,the alternative refrigerants are hydrocarbon refrigerants,R1234yf,R152a,etc.But these refrigerants are flammable substance,which hindering their using.Firstly, the fire risk parameters of these flammable refrigerants were introduced.The research progress about consequences and possibility of fire accidents after using these flammable refrigerants were introduced.Finally,the further research of automotive air conditioner using flammable refrigerants is also discussed.
