Caractérisation des compresseurs à piston fonctionnant aux mélanges azéotropes.

Characterization of the reciprocating compressor working with azeotropic blends.

Auteurs : HMEL'NÛK M., VOZNY V., MAZUR V.

Résumé

The hermetic reciprocating compressor, labelled GL60AA, from "Zanussi", with a nominal refrigerating capacity of about 0.1 kW was tested using both pure substances (R134a, R152a, R600a) and their azeotropic mixtures by means of a specially designed characterization test rig according to the ISO 917 standard. Synthetic and mineral oils were used to study an influence of mixture composition and oil type on the energy efficiency of the compressor. It was found that a "breeding" of R134a or R152a by the natural refrigerant addition leads to an increase in COP and refrigerating capacity. The best compressor characteristics were observed with azeotropic compositions. A comparative analysis of compressor characteristics concerning interaction of azeotropic mixtures with mineral and synthetic oils is presented.
