Innovative thermal energy storage system for use in automobiles

燃油经济性的提高导致汽车设计中更多的能源管理。随着能源转换的减少，乘客舒适热需求将需要废弃能源的储存和再利用。这将有助于减少启动排放，缩短冷发动机和动力传动系统的燃料消耗，通过主动加热动力传动系统油。预计混合动力和电动汽车将更加重视这项技术。使用发动机冷却液进行机载存储的主要障碍是储热密度低、80-100摄氏度的低温水平和高热泄漏。化学蓄热具有较高的蓄热密度和操作温度限制，但缺乏可演示的操作。本研究的目的是确定一种合适的金属氧化物氢氧化物反应器，以有效地储存和释放内燃机废气能量。调查将比较功能与已知的和可行的改进，以显热和潜热储存技术。金属氧化物氢氧化物储热回收技术被认为是一种很有前途的技术，但对反应器力学的了解还不够。同时，将研究基于相变材料的潜热储存，以确定化学和潜热储存系统的相对优势。这项工作将导致更好地理解反应堆设计和操作问题的机制，这将使其商业应用。

Increased fuel economy leads to more energy management in automotive design. With less energy conversion the passenger comfort heat demand will require waste energy storage and reuse. This would contribute to reduced start up emissions and shorter time period of increased fuel consumption of a cold engine and power train through active warming of the power train oils. Even greater emphasis of this technology is expected for hybrid and electric vehicles. A major barrier to on board storage using engine coolant suffers from low heat storage density, low temperature level at 80-100oC and high heat leakage. Chemical heat storage offers high heat storage density and operational temperature limits but suffers from lack of demonstrable operation. The purpose of this study is to determine an appropriate metal oxide hydroxide reactor to efficiently store and release internal combustion engine waste exhaust energy. The investigation will compare functionality against the known and viable improvements to sensible and latent heat storage technology. Metal oxide hydroxide heat store and retrieval is considered a promising technology lacking sufficient reactor mechanics understanding for commercial applications. At the same time, latent heat storage based on a phase change material will be investigated to identify the relative advantages of chemical and latent heat storage systems. This work will lead to better understanding of the mechanics of reactor design and operational issues that will enable its commercial applications.
