Refrigerants are classified according to their way of absorption or extraction of heat from substances stored in the refrigerator. Classification can be divided into class 1, class 2, class 3. Class 1 refrigerants used in the standard compression type cooling system. Class 2 refrigerants are used as direct cooling between the
Discuss the importance of selection of suitable refrigerant in a refrigeration system (Section 26.1). 2. Classify refrigerants into primary and secondary, and discuss the important differences between primary and secondary refrigerants (Section 26.2). 3. Discuss refrigerant selection criteria based on thermodynamic,

Standard 34. ASHRAE Standard 34, Designation and Safety. Classification of Refrigerants, establishes a simple means of referring to common refrigerants rather than by their chemical name, formula, or trade name. ASHRAE assigns numbers and safety classification to the refrigerants based on toxicity and flammability.

The refrigerants are numbered with an R-, followed by the HFC-number, given by the rules of the fluorocarbons numbering system. Isomers are identified with lower cases (ex R 134a). HFC refrigerant blends (i.e. mixtures of pure refrigerants), are numbered after the internationally accepted ASHRAE nomenclature. Blends
Classification of refrigerants. This text is based on the American standard ANSI/ASHRAE 34 published in 2001 and entitled “Designation and Safety Classification of Refrigerants". This classification makes it possible to designate all refrigerants used in a clear and internationally recognized manner by classifying them
