Résumé

The investigations, performed on a described facility, include the effect of capillary length, capillary diameter, refrigerant subcooling, condensing pressure and type of refrigerant on the mass flow-rates through the capillaries. The experiments were performed with CFC-12, HFC-134a and HC-600a, and at different condensing pressures and levels of subcooling under choked flow conditions. Eight different capillaries were used, and extensive data (exceeding 1000 sets) were collected. A conventional, dimensional analysis was performed to derive correlations to predict the mass flow rates for different refrigerants. The developed correlations are found to be in good agreement with the measured data.
