Résumé

One drawback to the implementation of compact heat exchangers is non-uniform distribution of liquid in the manifold. In order to improve the distribution pattern, an effective means of measuring the liquid distribution among the heat exchanger tubes has been developed. The flow rates were measured using collection tanks mounted on load cells using a batch method. This apparatus is a useful tool to quantify the effects of nonuniform distribution of liquid in the manifolds and to correct any eventual maldistribution.
