Summary: Sugar alcohols are utilized as heat storage materials due to their high latent heat, with their melting points ideal for recovering unused heat. In this study, the apparent specific heat of sugar alcohol slurries was investigated to estimate heat storage capabilities, with erythritol and mannitol used as the sugar alcohols. The proposed model showed good agreement between calculated values and experimental data, indicating the significant impact of freezing-point depression on the apparent specific heat of the sugar alcohol slurries.

Summary: This study reports the synthesis of microencapsulated phase change materials (MEPCMs) using metallic Sn as the core and sol-gel coated SiO2 as the shell. The microcapsules undergo a high temperature heat treatment, resulting in a self-repairing effect and high stability over 100 cycles. The melting point and latent heat of the microcapsules are similar to the theoretical values of metallic Sn.

Summary: Microcapsules based on Cu2O with different phase change materials (PCM) were prepared and characterized. Various techniques were used to characterize the elemental, structural, and electronic properties of the Cu2O-based microcapsules. The thermal properties of the microcapsules were also studied to analyze their potential as a thermal energy storage medium. Good stability and high encapsulation efficiency were observed, and an increase in isobaric specific heat was found for microcapsules based on paraffin wax compared to pure Cu2O.

Summary: This study presents a novel dynamic model for a latent cold thermal storage unit using water as the phase change material (PCM). The model integrates transient energy balances for PCM capsules and heat transfer fluid (HTF), and uses the apparent heat capacity approach to simulate PCM phase transition processes. The model is validated through experimental data and used to analyze the influence of various parameters on storage performance. The results show that the melting process of PCM varies in different directions within the storage unit. The study also suggests that the height of the tank and the diameter of the capsules impact the discharge period, while the initial temperature of the storage tank has minimal effect. To improve performance and reduce energy consumption, a compromise between HTF flow rate and capsule diameter needs to be determined.

Summary: This study synthesized mesoporous and macroporous SiOC ceramics using polydimethylsiloxane with different viscosities, and found that the thermal conductivities of gas phase and solid phase inside the porous structure increase with increasing pore size at the nanometer scale, while the overall thermal conductivity of the porous structure decreases. The findings suggest strategies for designing SiOC porous ceramic super-insulation materials with extremely low thermal conductivity.
