Since the Montreal Protocol was signed, the extensive research on CFCs and HCFCs alternatives has been uninterrupted. A new generation of HFCS refrigerants has begun commercial production, such as R407C refrigerant has been widely used in the field of rail air conditioning such as high-speed rail, bullet train, subway, etc., but R407C refrigerant will also be replaced due to its high greenhouse effect.
