Distribution diphasique du frigorigène dans des collecteurs constitués de tubes circulaires.

Two-phase refrigerant distribution in round tube manifolds.

Résumé

Two-phase refrigerant flow distribution in round tube heat exchanger manifolds has been investigated. Experimental data have been acquired in a heat exchanger test rig specially made for measurement of mass flow and phase distribution in the manifolds of compact heat exchangers. Horizontal round tube manifolds with 8 and 16 mm inner diameter and ten upward oriented heat exchanger tubes were used in the experiments, and CO2 and HFC-134a were used as refrigerants. The experimental data are compared to existing semi-empirical models for phase split in T-junctions.
