Technical background: The PhD studentship will investigate possible utilisation of low-grade heat sources, for example surplus low grade heat from the new automotive paint shop of NISSAN UK being designed by GEICO TAIKISHA and which will be opened in March 2017. The objective of the research is to introduce a framework to ease the environmental characterization and improvement in end use energy demand. Energy efficiency has quickly become a top priority because of the high energy use in industrial operations, which are responsible for significant CO2 emissions and thus, climatic changes. An automotive manufacturing plant has very large energy use and the painting shop example is particularly major responsible for this. The application of the framework will identify opportunities for improving energy use in order to achieve a reduction in operating costs and greenhouse gas emissions. In industry, a significant amount of energy is commonly used by equipment such as pumps, compressors, boilers, prime movers, ovens, chillers, dryers, process heaters, process coolers, ventilation equipment, etc. Thermal energy loss in each operation cannot be avoided and therefore manufacturing industry, characterised by a large number of operation units, has an inevitable large source of thermal energy loss. Hence, with higher energy cost and the increased importance of rationalising energy use, thermal energy management is likely to become an increasingly fundamental issue in the future. Decreasing the amount of end-use energy demand would help NISSAN to achieve sustainable processes with subsequent important results in terms of cost competitiveness and making progress toward environmental goals. This can be achieved by recovering low-grade heat (T<260 C), which if not captured and used, is mostly released into the atmosphere, thus giving rise to energy and resource losses and missing an energy efficiency opportunity. Innovative technologies will be assessed for their ability to recovery this energy and the scope of their utilisation. Project summary: In order to identify and estimate all the possible low-grade heat sources and to utilise them, it is firstly required to evaluate how much heat can be theoretically recovered from the industrial processes. This evaluation will be done through a pinch and exergy analysis. Pinch analysis is a methodology for minimising the energy consumption of processes by calculating thermodynamically feasible energy targets and achieving them by optimising heat recovery systems, energy supply methods and process operating conditions. At the same time, exergy analysis results to aid in determining the potential usefulness of a given low-grade heat source and determine the maximum amount of mechanical work which can be obtained. After the characterisation of available low grade heat sources, the most appropriate innovative technical solution for recovery and utilisation will be evaluated in order to assess the potential end use energy reduction obtained. An economic analysis of the solutions will be conducted to explore the impact on capital and operational costs to determine payback periods and commercial viability. Project outcomes: Detail techno-economic reports analysing innovative solutions to utilise low grade heat sources to reduce manufacturing energy demand. It is expected that at least 4 high impact publications in leading journals such as Applied Energy and Applied Thermal Engineering. In addition, 3 presentations at world leading conferences such as Sustainable Energy Technology, and Heat Powered Cycles.

技术背景：博士生将研究低品位热源的可能利用，例如由GEICO Tykisha设计的日产英国新汽车油漆车间的剩余低品位热量，该车间将于2017年3月开业。这项研究的目的是介绍一个框架，以简化环境特征和改善最终用户能源需求。能源效率迅速成为当务之急，因为工业运营中的高能源使用导致了大量的二氧化碳排放，从而导致了气候变化。一家汽车制造厂的能源消耗非常大，油漆车间的例子尤其对此负有主要责任。该框架的应用将确定改善能源使用的机会，以实现业务成本和温室气体排放的减少。在工业生产中，泵、压缩机、锅炉、原动机、烤箱、冷水机组、干燥机、过程加热器、过程冷却器、通风设备等设备通常要消耗大量的能量，每一道工序的热能损失都是不可避免的，因此以大量运行单元为特征的制造业不可避免地存在着大量的热能损失。因此，随着能源成本的上升和合理使用能源的重要性日益增加，热能管理很可能成为未来一个日益根本性的问题。减少终端能源需求量将有助于日产实现可持续的流程，从而在成本竞争力和朝着环境目标取得进展方面取得重要成果。这可以通过回收低品位热量(T&lt；260℃)来实现，这些热量如果不被捕获和使用，大部分会释放到大气中，从而导致能源和资源损失，并错失提高能效的机会。将对创新技术进行评估，以确定其回收能源的能力和利用范围。项目概述：为了识别和评估所有可能的低品位热源并加以利用，首先需要评估理论上可以从工业过程中回收多少热量。这项评估将通过夹点和火用分析进行。夹点分析是一种通过计算热力学上可行的能源目标，并通过优化热回收系统、能源供应方法和工艺操作条件来实现这些目标，从而将工艺的能耗降至最低的方法。同时，火用分析结果有助于确定给定低级热源的潜在有用性，并确定可以获得的最大机械功。在确定可用低品位热源的特性后，将评估最合适的回收和利用创新技术解决方案，以评估所获得的潜在终端能源削减。将对这些解决方案进行经济分析，以探讨对资本和业务成本的影响，以确定回收期和商业可行性。项目成果：详细的技术经济报告，分析利用低品位热源减少制造业能源需求的创新解决方案。预计在《应用能源》和《应用热能工程》等领先期刊上至少发表4篇影响力较大的文章。此外，在可持续能源技术和热力循环等世界领先会议上发表了3次演讲。
