Abstract: This paper examined the thermophysical properties of hydrate using disodium hydrogenphosphate 12H2O to develop a long-term latent heat storage (LTLHS) using supercooling. The thermal conductivities of solid and liquid disodium hydrogenphosphate 12H2O were measured using the transient plane source (TPS) technique. Results showed that the thermal conductivity of liquid disodium hydrogenphosphate 12H2O increased slightly with temperature, whereas the solid phase showed a minor downward trend. Also, thermal conductivity of the liquid phase was almost identical to the behavior of distilled water, and was approximately half as large as the thermal conductivity of the solid phase.
