Abstract

This study offers a comprehensive overview of the recent advances in various aspects of district heating systems (DHSs), focusing on the fourth and fifth generations of heat distribution networks integrated with different renewable energy sources (RES). The study highlights the integrated approach of various advanced renewable technologies applied to DHSs, such as solar and geothermal energy, biomass, industrial waste heat, and especially the implementation of conventional heat pumps (HPs) and solar-assisted HPs with solar thermal (ST), photovoltaic (PV), or PV-thermal (PV/T) panels in resilient and sustainable buildings and DHSs to increase energy and environmental performances. The ineffectiveness of refrigerant can be used to evaluate quickly the HP energy efficiency only with the values of the operating temperatures, and to evaluate the energy performance of the HP-PV/T hybrid system, the use of the global seasonal performance factor ((SPF_HP-PV) is also considered. Additionally, it shows the possibility of recovering excessive pressure from DHSs using pumps working as turbines. The study also describes the major components and evolution of DHSs, briefly reviews low and ultra-low temperature DHSs, and implementation of borehole and hot water TES technology into DHS. It also discusses the main optimisation techniques, simulation tools, control methods, and maintenance for DHSs, as well as alternative connection modes of RES to DHS. Finally, some original research and a literature review are included on several applications of implementing various RES in resilient and sustainable buildings and DHS.

详尽概述将可再生能源纳入区域供热系统的进展情况

本研究全面概述了区域供热系统（DHS）各方面的最新进展，重点关注与不同可再生能源（RES）集成的第四代和第五代热分配网络。该研究强调了将各种先进的可再生能源技术（如太阳能和地热能、生物质能、工业废热）应用于区域供热系统的综合方法，特别是在弹性和可持续建筑及区域供热系统中采用传统热泵（HPs）和太阳能辅助热泵（HPs），并配备太阳能热板（ST）、光伏板（PV）或光伏热板（PV/T），以提高能源和环境性能。制冷剂的无效性仅可用于快速评估工作温度值下的 HP 能源效率，为了评估 HP-PV/T 混合系统的能源性能，还考虑了使用全球季节性性能系数（SPFHP-PV）。此外，研究还展示了使用作为涡轮机工作的泵回收 DHS 过高压力的可能性。本研究还介绍了 DHS 的主要组成部分和演变过程，简要回顾了低温和超低温 DHS 以及在 DHS 中采用钻孔和热水 TES 技术的情况。报告还讨论了 DHS 的主要优化技术、模拟工具、控制方法和维护，以及可再生能源与 DHS 的替代连接模式。最后，还包括一些原创性研究和文献综述，内容涉及在弹性和可持续建筑及 DHS 中实施各种可再生能源的若干应用。
