%X 对1 m×2 m×0.35 m逆流太阳能溶液集热/再生器进行实验研究,分析了影响太阳能溶液集热/再生器再生效率的各种影响因素.实验研究发现,常温溶液再生存在明显两段式分布,溶液再生效率随空气流量的增加先增后减,存在最大值;溶液再生效率随溶液流量增加而递减.加热溶液综合再生效率升高;而加热再生用空气其综合再生效率下降.采用含湿量为20 g/kg再生用湿空气的再生效率比用含湿量为10 g/kg的再生用湿空气的再生效率小0.16.随着太阳辐射强度的提高,溶液再生效率也相应增加.因此,逆流太阳能溶液集热/再生器应在空气较干燥、太阳辐射强度较高时运行,并选取适合的空气流量.<br>A countercurrent solar solution collector/regenerator(C/R)with experiment platform the size of 1 m(wide)×2 m(long)×0.35 m(high)was used for analyzing the factors influencing regeneration efficiency of solar C/R. It is found that there is an obvious two-stage distribution for regenerating solution at normal temperature. The regeneration efficiency of solution increases first and then decreases with the increase of air mass flow rates and there exists a maximum value. The regeneration efficiency always decreases with the increase of solution flow rates. Heating solution leads to an increase of integrated regeneration efficiency; however, heating regeneration air decreases the integrated regeneration efficiency. The regeneration efficiency is decreased by 0.16 by using humid air of 20 g/kg instead of using humid air of 10 g/kg. The regeneration efficiency increases correspondingly with the increase of the solar radiation intensity. The countercurrent solar solution C/R can operate better in dry air and high solar radiation conditions and a suitable air flow-rate should be selected to achieve better performance
