摘  要  本文结合热舒适性条件，在典型的上海夏季工况下，比较分析太阳能驱动转轮式两级除湿空调和传统电压缩式空调
的热力性和经济性。结果显示太阳能两级转轮除湿空调系统都可以提供满足要求的送风，推荐的再生温度为 85o
C。与传统
电压缩式空调相比太阳能两级转轮除湿空调系统属于全新风系统，送风质量和室内空气品质都大大提高。与此同时除湿系统
可以节省70%的电耗，所以除湿系统高的初投入可以通过节约的运行成本获得补偿，系统的回收期为7年。

Abstract   In this paper, both the thermodynamic and economic performance of a solar driven two-stage rotary
desiccant cooing system and a conventional vapor compression system are analyzed and compared under typical
Shanghai summer condition. It is found that the solar driven desiccant cooling system could provide satisfied supply air
to the conditioned space and the recommended regeneration temperature is 85o
C. Compared with conventional vapor
compression system, desiccant cooling system is an all outdoor air system; therefore the quality of supply air is
improved. Also, solar driven desiccant cooling system could save 70% electrical consumption and then the high initial
cost of desiccant cooling system can be offset by the low operation cost. Simulated result show that the dynamic
payback period is about 7 years in Shanghai.
