| 摘 要： | 以上海地区某太阳能集热器驱动的单效溴化锂吸收式制冷系统为对象,对各主要部件负荷在典型日随时间变化的动态特性进行研究。结果表明:随着制冷能力的增加,发生器、冷凝器、吸收器及集热器面积需求量均增加;当制冷能力一定时,发生器与吸收器的负荷呈现先增加后减小的趋势,而集热器面积需求量的变化则与之相反。经济性分析可知结果表明,集热器费用为910、1040和1170$/m^2时,系统投资回收期分别为8.2、9.5及10.8 a,具有良好的社会效益和经济效益。

| Abstract: | A single-effect lithium bromide-water absorption refrigeration system driven by solar collectors in Shanghai is studied.The results show that as the cooling capacity increases,the generator,condenser,absorber and collector area requirements increase.When the cooling capacity is constant,the load of generators and absorbers tends to increase and then decrease,while the demand of collector area changes in the opposite direction.According to the economic analysis,the investment recovery period of the system is 8.2 years,9.5 years and 10.8 years when the per square meter of collector cost is$910,$1040,$1170,which has good social and economic benefits. |
