摘要

本系统综述通过综合进展、应用和现有知识差距，阐述了可再生能源（RE）在生活热水（DHW）生产中的应用的零散研究格局。从7个数据库的23,990条记录中，筛选并系统分析了2020年至2025年5月期间发表的105篇文章。结果显示，太阳能在独立系统（80.95%）和混合系统中占主导地位，主要是在小型装置中。次要贡献者包括空气源热（3.81%）、二氧化碳（3.81%）、废水（2.86%）、氢气（1.90%）和生物质（0.95%）。再生电力（太阳能/风能）和热能（太阳能辅助空气源热泵）显示出巨大的实施潜力，发电显示出优越的温室气体（GHG）减少能力。综合可再生能源系统将太阳能利用率提高到78%，温室气体排放量减少到60% - 92.69%，而光伏-热（PVT）系统的平均成本最低，投资回收期较好（5.24年）。出现了五个关键挑战：(1)不发达的电力存储解决方案；(2)不完整的可持续性评估框架；(3)供需协调不足；(4)高成本的热能存储（TES）加上相对较低的效率；(5)缺乏定制的优化工具。未来的战略研究重点可能包括：区域DHW供应的多可再生能源整合，需要进行研究以实现能源供应和消费的合理配置；通过相变材料和下一代技术提高性能；综合评价指标的制定；软件嵌入式优化算法；以及水安全保证协议。该研究为加快可再生能源在土豆泥生产中的应用提供了有价值的参考和可操作的指导。

Renewable energy for domestic hot water production: Advances, challenges, and future directions - A systematic review

This systematic review addresses the fragmented research landscape of renewable energy (RE) applications in domestic hot water (DHW) production by synthesizing progress, applications, and existing knowledge gaps. From 23,990 records across seven databases, 105 articles published between 2020 and May 2025 were screened and systematically analyzed. Results reveal that solar energy dominates both standalone (80.95 %) and hybrid systems, primarily in small-scale installations. Secondary contributors include air-source heat (3.81 %), CO₂ (3.81 %), wastewater (2.86 %), hydrogen (1.90 %), and biomass (0.95 %). RE-generated electricity (solar/wind) and heat (solar-assisted air source heat pumps) demonstrate significant implementation potential, with electricity generation exhibiting superior greenhouse gas (GHG) reduction capacity. Integrated RE systems enhance solar utilization to 78 % and achieve GHG reductions to 60 %–92.69 %, while photovoltaic-thermal (PVT) systems show the lowest levelized cost with a better investment payback period (5.24 years). Five critical challenges emerge: (1) underdeveloped electricity storage solutions, (2) incomplete sustainability assessment frameworks, (3) insufficient supply-demand coordination, (4) high thermal energy storage (TES) costs coupled with relatively lower efficiency, and (5) the absence of customized optimization tools. In the future, strategic research priorities may include: multi-RE integration for regional DHW supply, which necessitates investigations to achieve a reasonable allocation of energy supply and consumption; performance enhancement through phase-change materials and next-generation technologies; the development of comprehensive evaluation metrics; software-embedded optimization algorithms; and water safety assurance protocols. This study provides a valuable reference and actionable guidance for accelerating RE adoption in DHW production.

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
