文档介绍：冰蓄冷空调技术在北京某工程应用的经济性分析
摘要:冰蓄冷空调系统可以使电力负荷“移峰填谷”,缓解季节性能源供应紧张,是一种具有广阔应用前景的空调技术。但由于影响其综合经济性的因素比较复杂,还没有得到广泛的应用。本文针对此问题进行了分析研究。首先运用DeST软件,对北京市某建筑空调负荷进行了动态的模拟计算,并在此基础上进行了设备的选型。然后通过优化控制的方法,用matlab和lingo软件,对其运行的经济性进行了分析。最后通过北京某工程实例进行分析计算,得到了其空调季的运行费用,并和常规的空调系统进行了对比,说明了在北京地区采用冰蓄冷技术,可以节省运行费用30%以上,因此具有广阔的发展前景和很高的推广应用价值。

Economical analysis of technique of ice-storage
applied in a project of Beijing
ABSTRACT ice storage air-conditioning system is a new technology to make balance of the electric supply, which relax the tension of the energy supply, and reduce the investment and running of air-condition system. this system has vast developmental outlook. But the affects of economic and optimization to ice storage air-condition system are plex, it has not been used widespread. So the study on economic analysis and optimization to ice storage air-conditioning system is on the paper. In the first step of the study, the cooling load was calculated by DeST, and the equipment was chosen based on it. In the next step, the study on economic analysis and optimization to ice storage air-conditioning system was analyzed by Matlab and lingo. Finally, a project of beijing was analyzed and the running cost of air condition season was gained. paring the results between the ice storage system and the general system, a great mount of running cost was saved by ice s
