The rapid global increase in cooling demand—especially in hot and humid regions—is intensifying pressure on electrical grids and accelerating the need for higher-efficiency vapour compression refrigeration systems (VCRS). This review evaluates heat pipe (HP) integration in VCRS using a three-pathway framework: (i) refrigerant-side enhancement, (ii) air-side heat recovery and latent-load management via heat pipe heat exchangers (HPHEs), and (iii) thermal management of electronic controllers. Particular emphasis is placed on a closed-loop HP configuration that couples the suction and liquid lines, achieving passive liquid subcooling and suction superheating without fluid mixing. Reported benefits include increased coefficient of performance (COP), reduced refrigerant charge, improved compressor reliability, and the potential elimination or downsizing of auxiliary components such as accumulators and reheaters. On the air side, HPHEs enable effective sensible and latent heat recovery in humidity-sensitive applications. In contrast, HP-based heat sinks and vapour chambers stabilise inverter and controller temperatures under transient electrical and thermal loads. Across all pathways, the review synthesises recent progress in HP geometries, working fluids—including nanofluids—fill ratios, orientation effects, and hybrid HP–VCRS architectures. It compares experimental, numerical, and field findings across applications such as food preservation, buildings, and data centres. The review concludes by identifying priority research gaps—including standardised test protocols, long-duration reliability assessment across multiple climates, multi-objective system-level optimisation, and scalable integration pathways—and presents a roadmap to accelerate industrial adoption of HP-integrated VCRS.

全球冷却需求的快速增长——特别是在湿热地区——正在加大电网的压力，并加速对高效蒸汽压缩制冷系统（VCRS）的需求。本综述使用三途径框架评估了热管（HP）在VCRS中的集成：(i)制冷剂侧增强，（ii）通过热管热交换器（hphe）的空气侧热回收和潜在负荷管理，以及（iii）电子控制器的热管理。特别强调的是一个闭环HP配置，它耦合了吸入和液体管路，实现了被动液体过冷和吸入过热，而没有流体混合。据报道，该技术的优点包括提高了性能系数（COP），减少了制冷剂充注量，提高了压缩机的可靠性，并可能消除或缩小了诸如蓄能器和再加热器等辅助部件的体积。在空气方面，hphe可以在湿度敏感的应用中有效地回收显热和潜热。相比之下，基于hp的散热器和蒸汽室在瞬态电和热负载下稳定逆变器和控制器的温度。在所有途径中，综述综合了HP几何形状、工作流体（包括纳米流体填充比）、取向效应和HP - vcrs混合结构的最新进展。它比较了食品保存、建筑和数据中心等应用的实验、数值和现场发现。该综述通过确定优先研究缺口（包括标准化测试协议、跨多种气候的长时间可靠性评估、多目标系统级优化和可扩展集成路径）得出结论，并提出了加速hp集成VCRS工业采用的路线图。

Polymer Electrolyte Membrane (PEM) fuel cells have emerged as key technologies in the global shift toward sustainable energy systems, owing to their high efficiency and environmental compatibility. However, effective thermal management-especially under high current densities and cold-start conditions-remains a critical challenge to commercialization and long-term performance. This review systematically evaluates thermal management strategies for PEM fuel cells based on research published over the past decade. Both active and passive cooling methods are examined, with a focus on performance, integration feasibility, and operational limitations. In addition to conventional air and liquid cooling systems, advanced techniques such as metal foam integration, phase change materials (PCMs), nanofluid-based cooling, and hybrid systems are reviewed. Key thermal performance indicators-such as average temperature (T_avg), maximum temperature (T_max), and the Index of Uniform Temperature (IUT)-are used to compare effectiveness. The results indicate that while air cooling and basic passive systems are suitable for low-power applications, they are insufficient for high-power demands. Liquid cooling improves thermal uniformity and is widely adopted in automotive applications. Meanwhile, hybrid (e.g. serpentine channel + metal foam) and PCM-enhanced systems show promise but face issues such as increased pressure drop, structural complexity, and material compatibility. The review also highlights the lack of standardized evaluation metrics, which hinders consistent benchmarking across studies. By addressing these gaps and synthesizing performance trends, this study provides a comprehensive reference to guide future research and design. Scalable, integrated thermal management solutions-particularly hybrid approaches-are essential to support the durability and commercialization of PEM fuel cell technologies.

聚合物电解质膜（PEM）燃料电池由于其高效率和环境兼容性，已成为全球向可持续能源系统转变的关键技术。然而，有效的热管理，特别是在高电流密度和冷启动条件下，仍然是商业化和长期性能的关键挑战。本综述基于过去十年发表的研究，系统地评估了PEM燃料电池的热管理策略。研究了主动和被动冷却方法，重点是性能、集成可行性和操作限制。除了传统的空气和液体冷却系统，先进的技术，如金属泡沫集成，相变材料（PCMs），纳米流体为基础的冷却，和混合系统进行了回顾。关键的热性能指标，如平均温度（Tavg），最高温度（Tmax）和均匀温度指数（IUT），用于比较有效性。结果表明，虽然空气冷却和基本被动系统适用于低功率应用，但它们不足以满足大功率需求。液体冷却提高了热均匀性，并广泛应用于汽车应用。与此同时，混合（如蛇形通道+金属泡沫）和pcm增强系统显示出前景，但面临压力降增加、结构复杂性和材料兼容性等问题。该综述还强调了缺乏标准化的评估指标，这阻碍了研究之间的一致基准。通过解决这些差距和综合性能趋势，本研究为指导未来的研究和设计提供了全面的参考。可扩展的集成热管理解决方案，特别是混合方法，对于支持PEM燃料电池技术的耐用性和商业化至关重要。

The maritime industry must transition to alternative fuels to ensure efficiency, safety, and sustainability. This paper addresses critical questions regarding the feasibility of alternative fuels in delivering net-zero carbon power. It evaluates the readiness of some of the most promising zero-carbon fuels and examines their integration with land-based infrastructure for shore power connections. The study analyses the adoption of alternative fuels across various ship types, including passenger and merchant vessels, while accounting for future fuel availability. A key component of this research is a custom-developed tool that dynamically simulates ship operations to evaluate energy demands and emissions on a semi-quantitative basis. The tool leverages detailed ship data, including class and dimensions, to establish onboard load profiles and propulsion demands. In addition, a Python-based algorithm was developed to define ship routes by retrieving real-time position data. The study focuses on alternative fuels such as LNG and methanol, including their bio and e-fuel variants, to assess their potential in decarbonising the maritime sector. Key performance indicators are used to measure the environmental and operational impacts of these fuels across different vessel classes. The findings provide strategic insights into the implementation of zero-carbon fuels in the short, medium, and long term, offering a roadmap for achieving decarbonisation targets. Results highlight LNG as a more favourable solution compared to methanol, owing to its higher energy density and economic competitiveness. Moreover, incentives plays a pivotal role in supporting transition, with an average required value decreasing from approximately 1172 €/t_CO2 in 2023 to 81.8 €/t_CO2 by 2040.

Wind turbine blades (WTBs) are critical components that significantly influence energy capture efficiency and operational safety. However, they face diverse damage mechanisms in harsh environments, resulting in maintenance costs exceeding 20% of revenue for offshore installations. While various condition monitoring technologies exist, current research lacks integration, focusing on individual technologies without providing a comprehensive health management framework. Moreover, the quantitative mechanisms linking damage to performance degradation remain poorly understood, hindering effective predictive maintenance. This systematic review addresses these gaps by introducing a novel lifecycle health management (LCHM) framework that links damage mechanisms to proactive decision-making. Central to this framework is a hierarchical damage identification system comprising two progressive tiers: (1) damage detection, which determines the presence of anomalies, and (2) damage diagnosis, which localizes, classifies, and quantifies severity. Through critical comparison of widely used monitoring methods, applicable scenarios, limitations, and complementary strengths are identified. Furthermore, a comprehensive analysis of quantitative impact mechanisms is provided, demonstrating how different damage types affect aerodynamic efficiency, structural integrity, and power generation. Economic modeling reveals that implementing early proactive repair strategies can reduce lifecycle costs by up to 15% compared to traditional reactive approaches. The article concludes with a discussion of ongoing research challenges and prospects, highlighting promising future trends.

风力涡轮机叶片是影响能量捕获效率和运行安全的关键部件。然而，在恶劣的环境中，它们面临着各种各样的损坏机制，导致维护成本超过海上设施收入的20%。虽然存在多种状态监测技术，但目前的研究缺乏整合，侧重于单个技术，而没有提供全面的健康管理框架。此外，连接损伤与性能下降的定量机制仍然知之甚少，阻碍了有效的预测性维护。本系统综述通过引入一种新的生命周期健康管理（LCHM）框架来解决这些差距，该框架将损害机制与主动决策联系起来。该框架的核心是分层损伤识别系统，包括两个渐进层：(1)损伤检测，用于确定异常的存在；(2)损伤诊断，用于定位、分类和量化严重程度。通过对广泛使用的监测方法的关键比较，确定了适用的场景、局限性和互补优势。此外，还提供了定量冲击机制的综合分析，展示了不同类型的损伤如何影响气动效率、结构完整性和发电。经济模型显示，与传统的被动修复方法相比，实施早期主动修复策略可以降低高达15%的生命周期成本。文章最后讨论了正在进行的研究挑战和前景，强调了有希望的未来趋势。

Periodic maintenance services are important for power system components to minimize potential failures and repair costs, improving system reliability, and postpone the need for constructing new generating units and transmission lines. The maintenance scheduling (MS) program is designed to optimally determine the planned outage periods of related units and lines for maintenance services. This work presents a critical review of generation and transmission MS strategies in both renewable and conventional power systems. It highlights key factors influencing optimal MS, such as the dynamics in electricity market, load demand, and reserve requirements. The concept of integrated MS (i.e., coordinated generation and transmission MS) is also discussed. The review covers MS frameworks for various renewable sources including hydropower, wind turbines, and photovoltaic systems, alongside conventional units such as thermal plants, gas turbines, and cogeneration systems. The review also deals with uncertainties, objective functions, and coordination of MS with broader power system problems, such as fuel limits, congestion, and carbon emissions. Moreover, the work emphasizes real-world MS programs implemented across different countries with giving key findings and research gaps. This study is beneficial for researchers seeking to advance the field in future studies and power utilities aiming to implement effective and efficient MS programs.

定期维护服务对于电力系统组件非常重要，可以最大限度地减少潜在故障和维修成本，提高系统可靠性，并推迟建设新发电机组和输电线路的需要。维护计划（MS）程序的设计是为了最佳地确定相关单元和线路的维护服务计划停机时间。本文对可再生能源和传统电力系统中的发电和输电MS策略进行了综述。重点分析了电力市场动态、负荷需求和备用需求等影响最优调度的关键因素。本文还讨论了集成质谱的概念（即协调发电和传输质谱）。该综述涵盖了各种可再生能源的MS框架，包括水力发电、风力涡轮机和光伏系统，以及传统装置，如热电厂、燃气轮机和热电联产系统。该报告还讨论了不确定性、目标函数以及MS与更广泛的电力系统问题（如燃料限制、拥堵和碳排放）的协调。此外，这项工作强调了在不同国家实施的现实世界的MS项目，并给出了关键发现和研究差距。本研究对寻求在未来研究中推进该领域的研究人员和旨在实施有效和高效的MS计划的电力公司有益。

Photovoltaic/thermal (PV/T) systems have emerged as a promising auxiliary energy source for ground-source heat pumps (GSHPs), effectively mitigating long-term ground thermal imbalance and reducing grid electricity dependence. Despite their significant potential, comprehensive reviews of hybrid PV/T-GSHP systems remain scarce in recent literature. This study addresses this gap through a systematic review of advancements reported in over 150 recent studies, with particular emphasis on system architecture, functional materials, multi-source coupling integration, and advanced control strategies. Key areas examined include optimized designs of ground heat exchangers and PV/T heat collection components, the incorporation of nanomaterials to enhance heat transfer and photovoltaic efficiency, hybrid configurations integrating air-source heat pumps, solar roadways, and biomass systems, as well as intelligent operational and energy management strategies. Recent progress demonstrates that synergistic optimizations in structure, materials, and energy coupling can achieve up to 20 % improvement in overall exergy efficiency, a 25.6 % reduction in PV panel peak temperature, and a heating coefficient of performance (COP) reaching 6.0. These findings provide critical insights into performance enhancement pathways for PV/T-GSHP systems, offering substantial implications for improving building energy efficiency and accelerating the realization of carbon peak and neutrality targets in the building sector.

光伏/热（PV/T）系统已成为地源热泵（GSHPs）的一种有前途的辅助能源，有效地缓解了长期的地热不平衡，减少了对电网的电力依赖。尽管具有巨大的潜力，但在最近的文献中，对混合PV/T-GSHP系统的全面综述仍然很少。本研究通过系统回顾最近150多项研究的进展来解决这一差距，特别强调系统架构、功能材料、多源耦合集成和先进的控制策略。研究的重点领域包括地面热交换器和PV/T集热组件的优化设计，纳米材料的结合以提高传热和光伏效率，集成空气源热泵，太阳能公路和生物质系统的混合配置，以及智能操作和能源管理策略。最近的进展表明，在结构、材料和能量耦合方面的协同优化可以实现高达20%的总火用效率提高，光伏面板峰值温度降低25.6%，加热性能系数（COP）达到6.0。这些发现为PV/T-GSHP系统的性能提升途径提供了重要的见解，为提高建筑能源效率和加速实现建筑部门的碳峰值和中和目标提供了重大意义。

The review identifies the main challenges and future opportunities for the secure integration of the digital twin concept into HVAC + R systems. The following are the notable challenges. Modeling bottleneck on the data level: data harmonization and ontologies that are the foundation for efficient digital twin integration; at the process level: Modeling for the behavior prediction of the system and service integration towards efficient decision-making; and at integration level: the lack of standardization of digital twin architectures, data acquistion and utilization to improve the control and even the design of next-generation HVAC + R systems. Addressing these challenges systematically is crucial for advancing the adoption and deployment of digital twin concepts in the building sector.

Boiler low-load stable combustion technology is a key means to solve the problem of unstable combustion in boiler during the deep peak shaving of coal-fired power units. This study provides a systematic review of boiler low-load stable combustion technology, including 1) low load stable combustion mechanism, 2) low load stable combustion methods for coal-fired boiler and 3) future development direction of technology. In essence, the boiler low-load stable combustion is to reduce the ignition heat of pulverized coal, provide sufficient ignition supply heat for pulverized coal, ensure the match between the speed of the pulverized coal gas flow and the flame propagation speed, and create a reasonable flame organization, so that the pulverized coal can be reliably ignited, propagated, and ultimately form a stable flame near the burner nozzle. The low load stable combustion methods mainly involve: fine operation adjustment of the boiler system itself and external auxiliary stable combustion methods. The former achieves stable combustion of the boiler at low load by optimizing air and coal parameters, as well as the structure and arrangement of the burner. The latter achieves stable combustion of the boiler at low load by enhancing the ignition supply heat provided by the external heat source involving combustion-supporting fuel, plasma, microwave, and electric induction heating. In the future, in-depth exploration of the mechanism is the cornerstone of the innovative development of low-load stable combustion technology. Meanwhile, its innovative development also lies in the multi-technology integration, policy-driven, and economic and environmental impact assessments. The review aims to assist researchers and engineers to gain fundamental understandings and critical view of boiler low-load stable combustion technology, and hopefully with the knowledge it could bring new opportunities for the future development of deep peak shaving of coal-fired power units.
