JSRAE Holds Seminar on Low-GWP Refrigerants

Since developed countries are in a situation in which not only production but also importation of hydrochlorofluorocarbons (HCFCs) such as R22 will be prohibited by the end of 2019, and it was also decided to phase down hydrofluorocarbons (HFCs) according to Kigali Amendment of Montreal Protocol, refrigerant issues have attracted a great deal of attention among stakeholders, and urgent issues are arising. Firstly, Prof. Kagawa, in his keynote lecture, explained the present status of low-global warming potential (GWP) refrigerants and steps toward their introduction.
