Summary

The use of two-phase secondary refrigerants makes it possible to reduce the amount of fluid used in compression systems. The continuous production of these fluids and especially the control of crystallisation remains a bottleneck for this technology. The article presents an abstract of selected results obtained during the PhD research by M. Faucheux, which was presented at ENITIAA in December 2006. The impact of surface roughness of a surface Rt on the degree of supercooling was first studied, and indicated that a power law function can be used to describe the observed phenomena. Crystallisation in a circulating fluid has been studied using a transparent plastic heat exchanger. Video images were used to assess the different phases of ice crystallisation. Temperature measurements in the flow as a function of time provided a better understanding of the retrodiffusion of the crystallisation front in the flow.
