Thermophysical Properties of Potassium Fluoride Tetrahydrate from (243 to 348) K

In this study, potassium tetrahydrate is being considered as a strong thermal energy storage material. Potassium tetrahydrate possess a low melting temperature and displays a large specific and volumetric enthalpy of fusion; all properties desirable of a thermal energy storage material. At temperatures ranging from 243 to 348 K, both solid and liquid potassium tetrahydrate were tested. The results obtained were then compared to two other potential thermal energy storage materials, with ...

Thermophysical properties of lithium nitrate trihydrate from (253 to 353) K

Lithium nitrate trihydrate (LiNO3·3H2O) has many traits that are desirable for thermal energy storage (TES) materials. This study tests the thermophysical properties of LiNO3·3H2O between 253-353 K in comparison to effective TES materials: water and paraffin. A TPS system measured the thermal conductivity of the solid LiNO3·3H2O samples using the transient plane source (TPS) method. Results showed that LiNO3·3H2O had a higher ...

Long-term supercooled thermal energy storage (thermophysical properties of disodium hydrogenphosphate 12H2O)

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 ...

Optimization of Instrument Cooling Time for Measuring Thermal Properties with the Thermal Constants Analyzer

This study aimed to determine the effect of instrument temperature cooling time on the accuracy of thermal conductivity measurements. Multiple samples, with varying thermal conductivities, were measured using the Thermal Constants Analyzer, and with five different cooling times. Cooling times, and their effect on the thermal conductivity results were analyzed, and appropriate cooling times were suggested, based on the findings....
