The UN Environment Programme (UNEP) and ASHRAE have produced a new publication to update the market on the current list of available refrigerants, their ASHRAE numbers and safety classifications.
As well as including the latest list of approved refrigerants, the new fact sheet explains ASHRAE’s numbering system and how this relates to the refrigerants. ASHRAE’s Standard 34 establishes a simple means of referring to common refrigerants rather than by their chemical name, and adds a safety classification based on the refrigerants toxicity and flammability.
