Summary: This study utilized a Vat Photopolymerization technique to 3D print a composite resin filament containing lauric acid (LA) as a phase change material (PCM). Through various tests, it was found that the composite with 50% LA additive exhibited the highest latent heat enthalpy value and a homogeneous internal structure. Although this material caused a decrease in mechanical properties, the study demonstrated the feasibility of real-time 3D printing of PCMs with resins, solving the leakage issue and providing important implications for energy storage and insulation.

Summary: In this study, different phase change materials (PCMs) were incorporated into gypsum panels by stabilizing them in biochar and lignin through vacuum impregnation technique. The goal was to produce an environmentally friendly shape-stabilized material that can be easily integrated into gypsum-based building components. The thermophysical performance and long-term stability of the obtained compounds were analyzed using various techniques. The results showed promising thermal buffer capability of the shape-stabilized samples, with a higher impregnation rate for a paraffin with a melting temperature of 21 degrees C. The samples exhibited relatively stable behavior for applications within typical local boundary conditions.

Summary: Phase change materials (PCM), known for their high thermal storage capabilities, are being explored for their potential in improving the thermal performance of building exteriors. This study focused on integrating microencapsulated PCM into cement render and foamed concrete, resulting in composites with reduced density and thermal conductivity. The PCM integration also added thermal energy storage and improved the compressive strength of the foamed concrete. The findings highlight the potential of PCM-based foamed concrete as lightweight cladding panels for building exteriors with enhanced thermal insulation and thermal mass.

Summary: The implementation of phase change thermal storage technology has the potential to reduce energy consumption and regulate indoor temperature. However, its practical effectiveness is significantly influenced by outdoor thermal conditions. A novel PCM concrete has been studied in building envelopes, and numerical simulations show that it is most effective in Paris, reducing indoor temperature fluctuations in summer. In contrast, it performs better in spring and autumn in cities with high summer temperatures. The effectiveness of this new PCM concrete is primarily impacted by outdoor solar-air temperature. Therefore, selecting an appropriate PCM with optimal phase change temperature zones is crucial when implementing this technology in diverse climatic zones.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Summary: This paper investigates the heat transfer mechanism and factors influencing thermal radiation in the process of supercritical water gasification (SCWG) of coal, and proposes a comprehensive numerical model to simulate the process. Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.

Summary: Pulsating Heat Pipes (PHP) are passive two-phase heat transfer devices with a simple structure and high heat transfer capabilities. The actual unpredictability of their dynamic behavior during startup and thermal crisis hinders their large-scale application. An experimental apparatus is designed to investigate these phenomena systematically. The results show that increasing the number of evaporator sections and condenser temperature improves the performance of PHP. The condenser temperature also affects the initial liquid phase distribution and startup time.
