摘　　要：本文首先阐述了太阳能固体除湿空调系统的原理,从转轮除湿机性能、转轮式除湿系统和太阳能热水系统等3方面分析了本系统的影响因素。而后对除湿前混合的一次回风系统、除湿后混合的一次回风系统和二次回风系统进行了对比,并以一实例进行了分析计算,得到了除湿效率、COP热、太阳能集热器面积随潜热占余热的比例的变化规律。最后,探讨了本系统的运行模式及其优缺点。In this paper,the principle of solar-powered solid desiccant air-conditioning system was firstly presented,also the influencing factors of solar-powered solid desiccant air-conditioning system were analyzed from the perspectives of the performance of rotary-wheel dehumidifier, rotary- wheel desiccant system and solar hot water system. Furthermore, three types of system were compared, including the primary return air systems with mixing before and after dehumidification, respectively, and the secondary return air system. Based on the calculation of an example, the relationships between the efficiency of dehumidification, coefficient of performance, the area of solar heat collector and the ratio of latent heat to surplus heat were obtained. At last,the operation modes and advantages and disadvantages of this system were discussed.
