Résumé

Based on the Buckingham Pi theorem, this study derives the dimensionless correlations to characterize a series-connected two-evaporator refrigerating system with propane as the refrigerant. Experimental data are substituted into the correlations to demonstrate the most relevant factors. Simplified correlations are then obtained. The analytical results show that the mass flow rate of refrigerant is primarily affected by the condensing pressure, length of the high-temperature capillary tube, and the subcooling of refrigerant, while the heat transfer coefficients of refrigerant in the evaporators are affected by the condensing pressure and the logarithmic-mean temperature difference of the specific evaporator.
