Résumé

Review of fluorinated refrigerants, blowing agents, products for extinguishers. General properties. Refrigerants: definitions, quality criteria. Properties of various fluorinated refrigerants: pure HFC refrigerants, refrigerant mixtures ("drop-in" or not). Advantages and drawbacks of substitutes to R22 (R407C, R410A). Azeotropic and zeotropic refrigerant mixtures: problems in servicing; composition of the refrigerant charge and of the circulating refrigerant. Propane-based products and fluorine ethers: refrigerants for high temperature heat pumps (characteristics of possible substitutes for R114 as well as zeotropic mixtures, possible substitutes for R11 and R114); blowing agents for rigid polyurethane (characteristics of possible substitutes for HCFC-141b); extinguishers (characteristics of possible substitutes for H 1301); fluorine ethers (properties, possible substitutes for R113 as solvents or as refrigerants in heat pumps). J.G.
