Abstract

This paper describes a heat pump investigation for GreenSCIES (GS), a fifth Generation district heating and cooling (5DHC) network in Islington, London. The paper describes the GreenSCIES concept integrating Mobility, Power and Heat into a Smart Local Energy System (SLES). At the heart of the system is an ultra-low temperature ambient loop network, which permits bi-directional flow within the pipes to allow energy exchange between heating and cooling customers at different times and in different locations, depending on where demand is at any given time. An existing data centre provides the primary source of waste heat for the scheme. Heat pumps in distributed energy centres are utilised to amplify the temperature of the ambient loop to deliver heat in connected buildings. The energy centres integrate heat pumps with building-mounted solar photovoltaic (PV) systems and electric vehicle (EV) charging points. The paper provides an overview of the integrated SLES concept, focussing on the heat pump selection and the short and long-term thermal storage options designed for the scheme. The results show that even the smaller constructible ‘New River’ scheme will save 5,000 tons of CO2e annually. This will tend to 100% as the grid decarbonise further. Therefore, the GS SLES concept applied to urban areas could deliver significant carbon emission savings in the UK and elsewhere. Practical application: Project GreenSCIES, is a detailed design study to develop a Smart, Local Energy System (SLES) for a large community in the London Borough of Islington. Our consortium have developed an innovative SLES concept, centred around a fifth generation district heating and cooling network. The GS ambient loop systems have negligible losses and much greater efficiencies than traditional district heat networks. As recognised by the UK Government’s Heat and Buildings Strategy, ambient loop systems should be considered where large-scale neighbourhood regeneration occurs. The proposed SLES concept applied to wider urban areas could deliver significant carbon emission savings in the UK.
环境循环区域供热和供冷网络集成移动,电力和跨季节存储
本文介绍了位于伦敦伊斯灵顿的第五代区域供暖和制冷(5DHC)网络GreenSCIES(GS)的热泵研究。本文描述了GreenSCIES的概念,将移动性、电力和热量集成到智能本地能源系统(SLES)中。该系统的核心是一个超低温环境环路网络,它允许管道内的双向流动,以允许不同时间、不同地点的供暖和制冷客户之间的能量交换,这取决于任何给定时间的需求。现有的数据中心为该计划提供了主要的废热来源。分布式能源中心的热泵被用来提高环境回路的温度,从而在相连的建筑物中输送热量。能源中心将热泵与建筑安装的太阳能光伏(PV)系统和电动汽车(EV)充电点集成在一起。本文概述了集成SLES概念,重点介绍了热泵的选择以及为该方案设计的短期和长期储热方案。结果表明,即使是较小的可施工“新河”方案,每年也将节省5000吨二氧化碳当量。随着电网进一步脱碳,这将趋于100%。因此,应用于城市地区的GS SLES概念可以在英国和其他地方实现显著的碳排放节约。实际应用:GreenSCIES项目是一项详细的设计研究,旨在为伦敦伊斯灵顿区的一个大型社区开发智能本地能源系统(SLES)。我们的财团开发了一个创新的SLES概念,以第五代区域供暖和制冷网络为中心。与传统的区域供热网络相比,GS环境环路系统具有可忽略不计的损耗和高得多的效率。正如英国政府的供暖和建筑战略所承认的那样,在发生大规模街区再生的情况下,应考虑环境环路系统。拟议的SLES概念适用于更广泛的城市地区,可以在英国实现显著的碳排放节约。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
