摘要:【中文摘要】 針對一個特定的對象,進行了太陽能吸收式空調系統壽命周期內的模擬計算及影響因素的分析,結果表明:(1)單純太陽能空調(無采暖與熱水供應)的經濟性很差,太陽能空調與供熱的復合系統的經濟性要優于單純的太陽能空調系統;(2)太陽能采暖與空調的復合系統,采暖與供冷的負荷比對系統的經濟性有很大影響,即使在z*佳的負荷比時仍無法和常規的系統競爭;(3)太陽能與生活熱水系統的負荷系統中,熱水負荷所占比重越大,經濟性越好,當太陽能空調使用生活熱水系統夏季多余的熱量時,太陽能空調系統經濟上可以和天然氣鍋爐+電動制冷機競爭,并具有很好的節能性和環境效益。 【英文摘要】 The solar air conditioning system for a special building is simulated within its life cycle.The results indicate that: 1) the economics of single solar air conditioning is very poor and can not compete with conventional systems,however the economics can be improved by the combination with solar heating; 2) the ratio of space heating load to cooling load has significant effect on the economics of the solar space heating & cooling hybrid system,but it can not compete with conventional systems even at the optimum point;3) the ratio of domestic hot water heating load to cooling load has great effect on the economics of the solar hot water heating & cooling hybrid system,it can compete with conventional systems when the solar air conditioning is driven by the redundant heat from solar hot water heat systems in summer and it has excellent energy-saving and environmental benefits. 【中文關鍵詞】 太陽能空調; 經濟性; 影響因素; 模擬分析【英文關鍵詞】 solar air conditioning; economics; diurnal storage; heating and cooling
