本文介绍了英国一项合作研究项目的结果，该项目以伦敦为例，重点研究地下铁路隧道废热的回收。该项目的目的是研究将伦敦地下铁路隧道的冷却与废热回收系统相结合的可行性。然后，回收的热量将被转移到热泵以提高其温度，然后再输送到区域供热网络进行再利用。本文介绍了冷热联供系统的设计方案，并建立了评价系统性能的模型。介绍了研究的一系列结果，并强调了在能源、碳和成本节约方面的潜在好处。本文还介绍了一个相关项目，该项目建立在这个案例研究的基础上，旨在确定和量化从一系列城市地下基础设施（如下水道和电缆隧道以及地下铁路隧道）中回收废热的潜力。潜在的热回收和输送方法将根据当地最终用户热需求的大小和位置进行调查。这两个项目都侧重于伦敦的废热回收，然而，其结果适用于大多数拥有地下基础设施系统的城市，无论是在英国其他地方还是在世界各地。
This paper describes the results from a collaborative research project in the UK, focussing on the recovery of waste heat from underground railway tunnels, using London as a case study. The aim of the project was to investigate the feasibility of combining cooling of London’s underground railway tunnels with a waste heat recovery system. The recovered heat will then be transferred to a heat pump to upgrade its temperature, before delivery to a district heating network for reuse. The paper describes the proposed design for the combined cooling and heating system and the model that has been developed to evaluate its performance. A range of results from the study are presented and the potential benefits in terms of energy, carbon and cost savings are highlighted. The paper also introduces a related project, which builds on this case study and aims to identify and quantify the potential for waste heat recovery from a range of urban subterranean infrastructures, such as sewers and cable tunnels, as well as underground railway tunnels. Potential heat recovery and delivery methods will be investigated, in relation to the size and location of local end-user heat demand. Both of these projects focus on waste heat recovery in London, however, the results are applicable to most cities with underground infrastructure systems, both elsewhere in the UK and around the world.
