Cooling energy is a vital foundation of modern society for refrigeration and air conditioning processes of various kinds. Currently cooling consumes up to 14% of the UK's electricity, with an annual cost of more than £5 billion. Therefore only the use of solar thermal energy or low-grade waste heat instead of electricity to generate cold can lead to a sustainable way of cooling. However both present absorption refrigeration and adsorption refrigeration technologies are unsuitable for domestic application due to their complexity and inefficiency.This project will develop a new adsorption approach that combines the advantages of absorption processes and adsorption processes by encapsulating the liquid sorbents. The encapsulated sorbents offer not only a much higher sorption quantity but also a much higher sorption rate, which in combination enables the adsorption refrigeration system to be more compact and efficient for domestic applications.This project will address different levels of the scientific and technological challenges of such a new adsorption cooling technology. At a material level a two-step microencapsulation-coating approach will be developed to produce encapsulated sorbents. At the device level, the adsorption/desorption dynamics of a sorption bed based on encapsulated sorbents will be investigated both numerically and experimentally to achieve optimal designs. At a system level, an advanced system will be developed with encapsulated sorbents and related sorption beds. A lab-scale integrated system will also be constructed to investigate and demonstrate its performance for domestic applications.

冷却能是现代社会各种制冷和空调过程的重要基础。目前，制冷消耗了英国14%的电力，每年的成本超过50亿英镑。因此，只有使用太阳能热能或低品位的废热来代替电力来产生冷才能导致可持续的冷却方式。然而，目前的吸收式制冷和吸附式制冷技术由于其复杂性和低效率而不适合国内应用。本项目将开发一种新的吸附方法，通过封装液体吸附剂，将吸收法和吸附法的优点结合起来。封装的吸附剂不仅提供了更高的吸附量，而且还提供了更高的吸附速率，这使得吸附制冷系统更加紧凑和高效的家庭应用。本项目将解决这种新型吸附冷却技术所面临的不同层次的科技挑战。在材料层面，将开发两步微封装涂层方法来生产封装吸附剂。在设备层面，将对基于封装吸附剂的吸附床的吸附/解吸动力学进行数值和实验研究，以实现最佳设计。在系统层面，将开发一个先进的系统，包括封装吸附剂和相关的吸附床。还将构建一个实验室规模的集成系统，以研究和验证其在国内应用的性能。
