Summary

Hydrates are fine solid particles capable of transporting large quantities of energy when circulated as slurry. The objective of this paper is to present the first results of thermal study on an experimental loop equipped with a heating tube. The measuring method was first validated on water making it possible and allowing to show that hydrate slurries have heat-exchange coefficients of the order of 3 000 W.m-2.K-1 for solid fractions close to 20% in terms of volume. These results show that their use in refrigerating plants would be a major advantage enabling the improvement of energy performances in the refrigeration field.
