LAir Dearman Engine for Power and Cooling in Confined Spaces

全球对电力和制冷的需求不断增加，导致化石燃料消耗和二氧化碳排放增加。根据国际能源署（IEA）的数据，到2040年，全球电力需求将比2015年增长70%以上。此外，预计到2060年，空间制冷的能源需求将超过空间供暖，到2100年将超过60%，达到10,000太瓦时。该项目将提供一个具有成本效益的零排放系统，用于密闭空间的动力和冷却，通过采用尖端的Dearman发动机（DE），一种目前由液氮（LN2）驱动的兰肯循环膨胀器来利用液态空气。使用LAir代替LN2为dearman提供了非常有吸引力的提议，因为它的可用性，更简单的生产过程，但最重要的是它的安全特性。伯明翰大学将与迪尔曼公司合作开发一种LAir驱动的迪尔曼发动机，并将其性能与LAir成分和从储存到排气的性能相关联。

The global demand for power and cooling is ever increasing leading to increased fossil fuel consumption andCO2 emissions. According to the International Energy Agency (IEA), the world’s demand for electricity willincrease by more than 70% by 2040 compared to the levels in 2015. Also, it is predicted that the energydemand for space cooling will overtake space heating by 2060 and will exceed it by 60% by 2100 to reach10,000TWh. The project will deliver a cost-effective zero emission system for power and cooling in confinedspaces, by adapting the cutting-edge Dearman Engine (DE), a rankine-cycle expander currently powered byliquid nitrogen (LN2) to utilise liquid air. The use of LAir instead of LN2 provides very attractive proposition forDearman given its availability, simpler production process but most importantly its safety features. TheUniversity of Birmingham in collaboration with Dearman will develop a LAir driven Dearman engine andcorrelate its performance with LAir composition and properties from storage to exhaust.
