Summary

Glycol, eutectic salts, and pure water can be used as cooling storage for thermal energy storage (TES) systems. This study investigates magnesium chloride (MgCl2) saltwater solution for TES systems operating at subzero temperatures. The experiments determined the phase change temperature during the solidification and melting phases. Differential scanning calorimetry (DSC) was used to verify the latent heat of the samples. The results of MgCl2 saltwater showed a similar phase change temperature of -34 ° C for higher concentration ratios and -32 ° C for lower concentration ratios. The samples experienced a subcooling temperature of approximately -45 °C and a supercooling degree of approximately 10 °C. Increasing the ratio from 14% to 25% also increased the phase-change period and decreased the time it took for the samples to reach the nucleation process. DSC thermograms for a concentration ratio of 21% measured the highest latent heat of 171 kJ/kg.
