Solar energy is a sustainable source that can be effectively utilized to address winter heating challenges in buildings. To ensure the efficient application of solar for purposes and maintain reliable performance system, integration phase-change materials (PCMs) thermal storage (TES) systems has emerged as crucial auxiliary approach. This study focuses on design simulation four TES structures: smooth, finned, metallic foam, foam-finned tubes. It explores their characteristics, such complete melting time heat flux, under various flow conditions. Additionally, residential building Xi’an selected object, where proposed system employed meet demand. Economic indicators, including initial investment payback period, are estimated using static evaluation method. The results highlight unit with tube 4800 s, which 88.3% less than smooth tube. Finally, based actual project, it determined an HTF rate 0.25 m/s, requires fewest devices (914) period 13 months.

A 2D numerical analysis was conducted to examine the melting performance of a shell-and-tube-type phase change material with two-layer copper foam having higher and lower porosity levels. The design parameters for these two layers metal consisted three different volume fill ratios (VFR) (30 %/70 %, 50 %/50 70 %/30 %) shapes (circular, semi-circular, elliptical) layer. results showed that semicircular-shaped low layer 30 % VFR had least time 475 s. When increased elliptical circular 394 However, at only shape 323 Furthermore, were compared uniform system, deduced system did not always have because it depended on porosities filled in layers. Additionally, an average foam, optimal combination observed performance.

Biogas heating plays a crucial role in the transition to clean energy and mitigation of agricultural pollution. To address issue low biogas production during winter, implementation multi-energy complementary system has become essential for ensuring stability. guarantee economy, stability, energy-saving operation system, this study proposes coupling solar with phase-change energy-storage system. The mathematical model was developed, taking an office building Xilin Hot, Inner Mongolia (43.96000° N, 116.03000° E) as case study. Additionally, Sparrow Search Algorithm (SSA) employed determine equipment selection optimize dynamic strategy, considering minimum cost balance between supply demand load. operating economy evaluated using metrics such payback period, load ratio, daily rate return. results demonstrate that balanced demand, yields significant economic benefits compared central period 4.15 years return 32.97% under most unfavorable working conditions. Moreover, development optimization strategy holds practical engineering significance, optimal scheduling is realized.

Industrial parks, characterized by the clustering of multiple factories and interconnected energy sources, require optimized operational strategies for their Integrated Energy Systems (IES). These not only aim to conserve industrial users but also relieve burden on power supply, reducing carbon emissions. In this context, paper introduces an optimization strategy tailored clustered factories, considering incorporation trading supply chain integration throughout entire production process each factory. First, a workshop model is established factory, accompanied consumption that accounts strict sequencing integration. Furthermore, unit models are devised IES then low-carbon economically scheduling outlined within park, aiming minimize total cost, including cost trading. Finally, case studies conducted paper-making park located in Zhejiang Province. Various scenarios compared analyzed. The numerical results underscore model’s economic merits, it offers technical support conservation emission reduction fields.
