Energy tunnel is thermally activated through embedding absorber pipes within the lining, where underground heat extracted and transferred above ground via a pump for building energy applications. offers advantages such as low carbon emissions, cleanliness, high efficiency, safety. The source can be either outside or inside tunnel. This article first categorizes tunnels into external internal tunnels, describes characteristics of environment these their methods construction, some practical projects. Subsequently, utilization systems with different sources are analyzed, underlining critical role transfer process being closely linked to arrangement sources. Factors affecting performance then reviewed measures enhance systematically discussed. Finally, future study application types proposed. Current research studies on primarily focus transportation mining extracting geothermal generated tunnels. However, waste currently insufficient. Moreover, design natural collection, structural safety facilities, along concerns regarding condensate water tunnel, necessitate further investigations.

PCM is a valuable construction material due to its energy efficiency, but leakage during phase changes poses challenges. This study developed cork storage aggregate (CESA) by vacuum impregnating with change (PCM) and coating it polymer silica fume address leakage. Experiments confirmed the suitability of CESA as building material, demonstrating compressive strength. Thermal analysis via differential scanning calorimetry showed decrease in enthalpy after impregnation, parafol-20Z displaying an 88 J/g compared 193.5 PCM. Despite reduced enthalpy, aggregates delayed temperature rise effectively tests. paraffin wax 1.48 times temperature-increasing time lag, 1.78 lag. These results meant that potential for energy-saving performance when this technology applied buildings. Laboratory experiments under varying ambient temperatures further significant heat capacity. findings highlight importance selecting based on external melting point optimal savings, reduce consumption construction.

Phase change material integration in concrete for thermal energy storage: techniques and applications in sustainable building

Sustainable Energy Research, Journal Year: 2024, Volume and Issue: 11(1)

Published: Dec. 3, 2024

Abstract The building sector is a significant contributor to global energy consumption, necessitating the development of innovative materials improve efficiency and sustainability. Phase change material (PCM)-enhanced concrete offers promising solution by enhancing thermal storage (TES) reducing demands for heating cooling in buildings. However, challenges related PCM leakage, mechanical strength reduction, encapsulation durability hinder widespread adoption. This paper critically reviews various incorporation techniques evaluates their impact on performance structural integrity. Our findings revealed that while integration improves efficiency, it reduces strength, especially at higher content. To address these challenges, recent work emphasizes advancements technologies property optimization, focusing mitigating leakage durability. Organic types are favored applications due compatibility, though issues with control retention remain unresolved. Hence, choice technique must balance application requirements, allowable reductions, cost constraints. Moreover, lack standardized methods assess long-term PCM-composite highlights need further optimize performance.
