摘要
本文搭建了太阳能驱动的自冷式除湿空调系统,实验研究了在上海夏季工况下,除湿阶段和再生阶段的切换时间、入口空气含湿量和再生热水入口温度对该系统除湿性能的影响。结果表明,系统除湿阶段和再生阶段的最佳切换时间为6min,当再生热水温度为70℃时,系统的除湿性能最佳,此时系统的热力性能系数为0.53,除湿量为9.23g/(kg干空气)。该系统可与太阳能等低品位热源结合应用于中、高湿地区。
A self-cooled desiccant air-conditioning system driven by solar energy is established in this paper. The effects of switching time in dehumidification stage and regeneration stage, inlet air humidity ratio and regenerative hot water inlet temperature on the dehumidification performance of the system are studied under Shanghai summer condition. The results show that the optimal switching time of the dehumidification stage and regeneration stage of the system is 6 min.?When the temperature of the regenerative hot water is 70 ℃, the dehumidification performance of the system is achieved best. At this moment, the thermal coefficient of performance (COP th ) of the system is 0.53, and the moisture removal is 9.23 g/(kg dry air). The system can be used in medium and high humidity areas in combination with low-grade heat sources such as solar energy.
