Summary

The aim of this work is to present the first heat-transfer results in an experimental refrigeration loop using CO2 hydrate slurries as a two-phase secondary fluid. In order to characterize the heat exchange of CO2 hydrate slurries, an experimental facility composed of a heating pipe and a plate-heat exchanger was designed to study local heat-transfer coefficients and energy restitution. The measurement method was validated on water, which allows for the determination of local heat-exchange coefficients of about 2500 Wm-2K1 for 18% vol of CO2 hydrates. These results are of the same order as those obtained in ice slurries. Thus, they also make it possible to highlight the good sored-energy restitution properties of hydrate slurries. The plate heat exchanger heat-exchange characterization has shown encouraging results but it did not make it possible to achieve continuous operation of the system.
