Analyse des fuites internes à travers le jeu radial d'un compresseur rotatif à palettes (RV-i) amélioré.

Analysis of internal leakage across radial clearance in the improved revolving vane (RV-i) compressor.

Résumé

The efficiency of the new compressor, alike other refrigeration compressors, is primarily affected by friction and internal leakage losses, amongst which the former has been investigated. In this paper, the leakage flow across the radial clearance between the rotor and the cylinder in the new compressor is analyzed. The dynamic characteristic of the radial clearance is theoretically formulated, and the leakage mass flow across the clearance gap is calculated based on a proposed method. It is found that the leakage loss at the radial clearance in the RV-i compressor is typically 40% lesser than that of the rolling piston type.
