| 摘 要： | 以显热效率、潜热效率和除湿性能系数作为评价指标,通过实验比较了硅胶和氯化锂转轮的除湿性能,研究了运行参数(处理空气进口湿度、温度,再生温度,处理风量)对转轮除湿性能的影响。实验研究发现在相同工况下,氯化锂转轮的显热效率、潜热效率均高于硅胶转轮。运行参数中再生温度、处理空气进口湿度对转轮除湿性能影响比较大。氯化锂转轮的最佳再生温度为60℃,硅胶转轮的最佳再生温度为100℃。说明氯化锂转轮更适合采用太阳能、废热等低品位能源作为再生热源。

| Abstract: | Sensible heat efficiency,latent heat efficiency and dehumidification coefficient of performance(DCOP) were employed to evaluate the performance of silica gel wheel and lithium chloride wheel.Some parameters,such as the inlet air humidity and temperature,the regeneration temperature,the air mass flow rate,which may affect the performance of the desiccant wheels,were also analyzed. It shows that the efficiency of LiCl desiccant wheel was higher than that of silica gel wheel under the same conditions,and the regeneration temperature and inlet humidity ratio have significant impact on the dehumidification performance of the two desiccant wheels.The optimal regeneration temperature was 60 ℃for lithium chloride wheel,and was 100 ℃ for silica gel wheel.It illuminates that the LiCl desiccant wheel is adapt to adopting the solar energy,waste heat as regeneration heat source. |
