Frozen brine buffers.

Author(s) : ARRIGHETTI C., CLEMENZI M., MUSTACCHI C.

Summary

A transient thermal model is developed for a cylindrical shell of brine cycled around its melting-solidification transition. Aim of this model is the design of devices exploiting such a transition to buffer the continuous cooling duty of an industrial plant when operating the refrigeration group only during the off-peak hours of the electrical load. Parametric simulations are carried out to explore the effects of the diameter and pitch of the tube carrying the driving fluid, the salinity of the brine, the surface heat flux, the daily duty of the cell and the maximum temperature allowed at the load. Results are submitted to dimensional analysis to obtain generalized relations between the dimensionless numbers describing the transitions.
