摘  要  本文結合熱舒適性條件，在典型的上海夏季工況下，比較分析太陽能驅動轉輪式兩級除濕空調和傳統電壓縮式空調
的熱力性和經濟性。結果顯示太陽能兩級轉輪除濕空調系統都可以提供滿足要求的送風，推薦的再生溫度為 85o
C。與傳統
電壓縮式空調相比太陽能兩級轉輪除濕空調系統屬于全新風系統，送風質量和室內空氣品質都大大提高。與此同時除濕系統
可以節省70%的電耗，所以除濕系統高的初投入可以通過節約的運行成本獲得補償，系統的回收期為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.
