Feasibility of a melting-brine cold storage system.

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

Summary

A feasibility study is carried out of a system consisting in a pool of freezing brine, thermally cycled to cumulate negentropy for supplying a cooling load. The duty cycle of the refrigeration compressors is limited to the off-peak hours of night. Internal rate of return of the required investment is explored as a function of electric power tariffs and required temperature of the cooling duty. The main design parameters are optimized: initial salinity, diameter of the tubes forming the bundle, pitch of these tubes and surface heat flux. It is found that in the range of loads from 0 to -20 deg C, the lower the temperature, the more convenient is this type of storage.
