Les applications des HFC comme frigorigènes.

The application of HFCs as refrigerants.

Auteurs : DIDION D. A.

Résumé

The technical criteria for using HFCs as refrigerants in the vapour compression cycle is presented. If thermodynamic performance is to be optimized, particular attention must be paid to the fluids' critical point and molar heat capacity. A reasonable balance between volumetric capacity, which implies equipment size, and COP is best achieved by selecting a refrigerant of appropriate vapour pressure. To achieve these balances for the many different applications, both azeotropic and zeotropic mixtures of HFCs are now in use. The characteristics and performance advantages and disadvantages of these mixtures are discussed. Additional physical properties of these refrigerants dealing with lubricant compatibility and safety considerations, i.e. toxicity and flammability, are also discussed.
