Refrigerant naming method

( 1) Inorganic compounds environmental protection refrigerants < p> inorganic compounds shorthand notation rules for R7 ( ) 。 Parentheses represent a set of Numbers, which is the integer part of inorganic molecular weight.

( 2) Halogenated hydrocarbon and alkane < p> the general formula of alkane compounds molecules to CmH2m + 2; The general formula of halogenated hydrocarbon molecules to CmHnFxClyBrz ( 2 m + 2 = n + x + y + z) , their sigil rules for R ( m - 1) ( n + 1) ( x) B( z) 。 Below for some refrigerants symbol, for example, < / p> 3) Non azeotropic mixed refrigerant < p> non azeotropic mixed refrigerants shorthand notation for R4 ( ) 。 Parentheses represent a set of Numbers, this group of Numbers to give a name to the refrigerant has serial number, start at 00.

( 4) Azeotropic mixture refrigerant < p> azeotropic mixture refrigerant shorthand notation for R5 ( ) 。 Parentheses represent a set of Numbers, this group of Numbers to give a name to the refrigerant has serial number, start at 00.

( 5) Naphthene, alkene and their halogenated < p> written symbols regulation: naphthene and naphthene halogenated begins with the letter 'RC', alkene and alkene halogenated begins with the letters 'R1'.

( 6) Any organic refrigerants in 600 sequence number < p> < / p> < p> < / p>
