吸收式空调系统是建筑可持续发展的绿色选择。然而，相对较低的性能阻碍了它的发展，因为在热再生过程中浪费了大量的能量。为了改进，提出了一种电容去离子(CDI)再生方法：它通过电极对再生吸收液，并通过降低能量损失来获得更好的性能。在一定的工作条件下，COP可达6。然而，目前的研究还没有充分探索实际性能，这是强烈影响的不同种类和浓度的不同的吸收剂。为了选择一种理想的吸湿剂进行优化，对不同吸湿剂溶液的实际性能进行了理论和实验研究。综合考虑再生效果和成本效益，揭示了不同参数对再生效果的影响。结果表明，含有溴化锂溶液的体系具有最高的COP。浓度为50%时可接近2，而氯化镁和氯化钙溶液具有较好的性价比。混合吸波剂可以在不牺牲性能的情况下降低成本，是一种更好的替代方案。这些进展可能会使基于电容去离子再生方法的吸收式空调系统具有更大的应用前景。
Absorption air-conditioning system is a green choice for buildings for sustainable development. However, comparatively low performance impedes its development, as much energy is wasted in the heat regeneration process. To improve, a capacitive deionization (CDI) regeneration method has been proposed: it regenerates absorbent solution with electrode pairs and achieves better performance by cutting the energy loss. The COP could reach 6 under certain working conditions. Nevertheless, the present research has not fully explored the actual performance, which is strongly affected by the varieties and concentrations of different absorbents. On the purpose of selecting an ideal absorbent for optimization, theoretical and experimental research has been made on the actual performance with different absorbent solutions. Considering both the regeneration effect and cost-effectiveness, it has revealed the influence of different parameters. The results show that the system with LiBr solution has the highest COP. It can approach 2 with a 50% concentration; while MgCl2and CaCl2solution have better cost-effectiveness. Mixed absorbent could be a better alternative plan by reducing the cost without sacrificing the performance. These progresses could make the absorption air-conditioning system based on the capacitive deionization regeneration method more promising for future application.
