電壓縮式空調(diào)相比太陽能兩級轉(zhuǎn)輪除濕空調(diào)系統(tǒng)屬于全新風(fēng)系統(tǒng)，送風(fēng)質(zhì)量和室內(nèi)空氣品質(zhì)都大大提高。與此同時除濕系統(tǒng)
可以節(jié)省70%的電耗，所以除濕系統(tǒng)高的初投入可以通過節(jié)約的運行成本獲得補償，系統(tǒng)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.
