摘要：【中文摘要】 针对一个特定的对象,进行了太阳能吸收式空调系统寿命周期内的模拟计算及影响因素的分析,结果表明:(1)单纯太阳能空调(无采暖与热水供应)的经济性很差,太阳能空调与供热的复合系统的经济性要优于单纯的太阳能空调系统;(2)太阳能采暖与空调的复合系统,采暖与供冷的负荷比对系统的经济性有很大影响,即使在最佳的负荷比时仍无法和常规的系统竞争;(3)太阳能与生活热水系统的负荷系统中,热水负荷所占比重越大,经济性越好,当太阳能空调使用生活热水系统夏季多余的热量时,太阳能空调系统经济上可以和天然气锅炉+电动制冷机竞争,并具有很好的节能性和环境效益。 【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. 【中文关键词】 太阳能空调; 经济性; 影响因素; 模拟分析【英文关键词】 solar air conditioning; economics; diurnal storage; heating and cooling
