"EPSRC : Elisangela Jesus D'Oliveira : EP/S023836/1"- Research council that the student is funded by the Engineering and Physical Sciences Research Council (EPSRC). - The student's name: Elisangela Jesus D'Oliveira- Training Grant Reference Number: EPSRC Centre for Doctoral Training in Renewable Energy Northeast Universities (ReNU), EP/S023836/1Heat represents almost half of the use of energy in the UK, and around 80% of domestic heat is supplied by natural gas. Therefore, we must reduce the heating demand by increasing the efficiency and decarbonisation of the space and hot water heating systems. The adoption of low-carbon domestic heating technologies is one of the biggest challenges in the decarbonisation of the UK's energy system because 80% of the homes are already built. The retrofitting of households is one of the most cost-effective routes to reduce carbon emissions.The use of LHTES has the potential to reduce the space heating energy use by storing excess energy and bridge the gap between supply/demand mismatch characteristic of renewable energy sources or electricity peak-load. The efficiency of domestic or residential radiator could be increased using a compact LHTES, and it could be implemented as a retrofit measurement to reduce energy consumption. There are some studies of LHTES in domestic heating. Campos-Celador et al. (2014) designed a finned plate LHTES system for domestic applications using water-paraffin, allowing a volume reduction of more than 50%, comparing to a conventional hot water storage tank. Dechesne et al. (2014) studied the coupling of an air-fatty acids heat exchanger in a building ventilation system; the module could be used either for space heating or cooling. Bondareva et al. (2018) studied a finned copper radiator numerically with paraffin enhancing with Al2O3 nanoparticles, and their results demonstrated that the addition of fins and nanoparticles increases the melting rate. Sardari et al. (2020) investigated the application of combined metal foam and paraffin for domestic space heating by introducing a novel energy storage heater; their results showed that the solidification time was reduced by 45% and the heat recovery was enhanced by 73%. Many studies have been conducted to investigate the enhancement of the thermal conductivity of the PCMs with the incorporation of high conductive nanomaterials, as they increase the heat transfer rate of the PCM to tailor the application charging and discharging rates. However, a study evaluating the feasibility of the nano-enhanced PCMs (NEPCMs) applications on domestic radiators to improve the efficiency and energy-savings through heat recovery has not been conducted. Therefore, a dedicated investigation was planned with the focus on deepening the knowledge and understanding of such a technology. The lack of proper design guidelines, cost and the rate problem have delayed the deployment of LHTES devices. Therefore, this study will build and experimentally evaluate the performance of the LHTES system proposed contributing to the development of the design guidelines. ReferencesBondareva, N.

“EPSRC：Elisangela Jesus D'Oliveira：EP/S 023836/1”-研究理事会，学生由工程和物理科学研究理事会（EPSRC）资助。- 学生姓名：Elisangela Jesus D 'Oliveira-培训补助金参考编号：EPSRC东北大学可再生能源博士培训中心（ReNU），EP/S 023836/1 Heat代表了英国近一半的能源使用，约80%的家庭供热由天然气提供。因此，我们必须通过提高空间和热水供暖系统的效率和脱碳来减少供暖需求。采用低碳家庭供暖技术是英国能源系统脱碳的最大挑战之一，因为80%的家庭已经建成。家庭改造是减少碳排放的最具成本效益的途径之一。LHTES的使用有可能通过储存多余的能量来减少空间加热能量的使用，并弥合可再生能源的供需不匹配特征或电力峰值负荷之间的差距。使用紧凑型LHTES可以提高家用或住宅散热器的效率，并且可以作为一种改造措施来实现，以降低能耗。目前国内对低温热交换器在供暖中的应用已有一定的研究。Campos-Celador等人（2014年）设计了一种使用水-石蜡的家用翅片板LHTES系统，与传统的热水储罐相比，其体积减少了50%以上。Dechesne等人（2014年）研究了建筑通风系统中空气-脂肪酸热交换器的耦合;该模块可用于空间加热或冷却。Bondareva等人（2018年）研究了一种带翅片的铜散热器，用Al 2 O3纳米颗粒增强石蜡，他们的结果表明，添加翅片和纳米颗粒增加了熔化速率。Sardari等人（2020年）通过引入一种新型储能加热器，研究了金属泡沫和石蜡组合在家用空间加热中的应用;他们的结果表明，固化时间缩短了45%，热回收提高了73%。已经进行了许多研究来研究通过掺入高传导性纳米材料来增强PCM的热导率，因为它们增加了PCM的传热速率以定制应用充电和放电速率。然而，尚未进行评估纳米增强型相变材料（NEPCMs）应用于家用散热器以通过热回收提高效率和节能的可行性的研究。因此，计划进行专门的调查，重点是加深对这种技术的了解和理解。缺乏适当的设计指南，成本和费率问题已经推迟了LHTES设备的部署。因此，本研究将建立和实验评估的LHTES系统的性能提出的设计准则的发展作出贡献。Bondareva，N.美国，Gibanov，N.美国，& Sheremet，M.
