Nomenclature Of Refrigerant

- May 12, 2017 -

(1) Inorganic compounds

The abbreviated symbols for inorganic compounds are prescribed for R7 (). The brackets represent a set of numbers, which are integral parts of the inorganic molecular weight.

(2) halogenated hydrocarbon and Alkane class

The molecular formula of alkane compounds is CmH2m 2; the molecular formula of halogenated hydrocarbon is CmHnFxClyBrz (2m 2 = n x y z), their shorthand notation is provided for R (M-1) (n 1) (x) b (z). The following illustration is an example of some refrigerant symbols

(3) non-azeotropic mixture refrigerant

The abbreviated symbols for non-azeotropic mixing refrigerant are R4 (). Brackets represent a set of numbers, which are named after the refrigerant sequence number, starting from 00.

(4) Azeotropic mixture refrigerant

The shorthand symbol for AZEOTROPIC mixing refrigerant is R5 (). Brackets represent a set of numbers, which are named after the refrigerant sequence number, starting from 00.

(5) Cycloalkanes, chain olefins and their halogenated compounds

Write symbols stipulate: Cycloalkanes and cycloalkanes halogen Agent with the letter "RC" beginning, chain olefins and chain olefin halogen compounds with the letter "R1" start.

(6) Organic refrigerant in 600 sequence arbitrary number
