摘 要： 根据LNG接气站冷量能级的特点，分析了LNG冷能用于冷库的实现形式，比较了LNG接气站冷能冷库的不同系统工艺流程及特点。在一定假设条件下，分析了其中一种流程的技术经济性。结果表明：该方案下的LNG冷能冷库系统运行费用较低，投资回收期小于1年，具有明显的经济效益和节能潜力。 关键词： LNG 冷能冷库 工艺流程 经济性分析 Comparation And Analyses Of System Process Flow Of Refrigerated Warehouse Utilizating Cold Energy From Lng Gasification Stations Wu Jiying Ma Yimin Zhao Xiaoming (Cleaning Combustion and Energy Utilization Research Center of Fujian Province，College of Mechanical Engineering, Jimei University, Fujian Xiamen, 361021) Abstract ：Accoding to the energy-level features of cold energy from gasification station, not only the mode of utilizing such cold energy at refigerated warehouse was analyzed, but also the varivious system process flow and corresponding features of such cold stores was compared in this paper. Under certain assumed conditions, the technological and economical analysis of one flow mode was made. Results indicate that the operation cost of the refrigerated warehouse under this mode is low, and its payback period will be no more than a year. So the economic benefits and energy-saving potential of it are significant. Key words ：LNG; cold energy refrigerated warehouse; process flow; economic analysis 参 考 文 献 [1] 王坤,顾安忠,鲁雪生等.LNG冷能利用技术及经济分析[J].天然气工业,2004,24(7):122-125 [2] 李静,李志红,华贲.LNG冷能利用现状及发展前景[J].天然气工业,2005,25(5):103-106 [3] 周廷鹤,彭世尼.LNG冷能利用技术探讨[J].上海煤气,2009(1):37-40 [4] 吴胜琪.利用LNG冷能于冷冻冷藏库与其他节能系统应用研究[D].台湾:中山大学,2003 [5] 曹文胜.LNG冷能利用冷库的流程模拟计算[J].冷藏技术,2008(3):27-30 [6] 吴集迎,马益民,陈仕清.LNG冷能用于冷库的系统设计及分析.集美大学学报.2010,15(1):44~47 [7] 葛轶群,章学来,赵兰等.LNG冷能的梯级利用[J].制冷技术,2006(3):14-16 [8] 焦琳,王烜,段常贵等.LNG气化站冷能利用方式的探讨[J].煤气与热力,2007,27(1):21-23
