针对溶液再生器冬季工况下的性能数据缺少问题
搭建了冬季工况下再生器性能实验台
实验研究了再生溶液为LiCl溶液时空气入口温度、空气入口含湿量、空气流量以及溶液入口温度、溶液入口浓度、溶液流量对再生器性能的影响
采用再生量和再生效率为评价再生器性能的指标.结果表明:在本实验的工况范围内
增大溶液流量
能够提高再生量和再生效率; 空气入口含湿量变化对再生量和再生效率影响不大; 提高空气入口温度会使再生量和再生效率略有增加; 增大空气流量会使蒸发量和再生效率降低; 提高溶液入口温度会使再生量增加而再生效率降低; 提高入口溶液浓度能够提高再生效率而再生量减小.
An experimental system was established to test the performance of a regenerator under winter conditions
and the experiment was conducted to investigate the effects of the inlet parameters of the air and the LiCl aqueous solution on the performance of the regenerator. The results show that both the evaporation rate and the humidity effectiveness increased with the increase in the desiccant flow rate. The increase in the inlet air humidity ratio almost had no influence on the evaporation rate and the humidity effectiveness. The evaporation rate and the humidity effectiveness increased slightly with the increase in the inlet air temperature and decreased with the increase in the air flow rate. The evaporation rate increased and the humidity effectiveness decreased with the increase in the inlet desiccant temperature. In addition
the evaporation rate decreased and the humidity effectiveness increased with the increase in the inlet desiccant concentration.
