【摘要】 空调蓄冷技术,即是在夜间用电负荷的低谷期,采用电动制冷机制冷,利用蓄冷介质的显热或潜热特性,用一定方式将冷量贮存起来并移至用电负荷较高的白天,也就是用电高峰期使用,以满足建筑物空调或生产工艺的需要。在空调蓄冷应用技术中,国内主要是采用静态冰蓄冷。本文针对冰蓄冷空调系统设计中的一些问题,通过在工程设计中采用设计方法、思路的分析研究,发现很多的设计者对于冰蓄冷空调系统的设计上观念还比较模糊,设计时没有摆脱常规设计观念的束缚,沿袭了常规空调系统的设计,导致设计保守,无法发挥冰蓄冷空调的优越性。冰蓄冷的推广离不开经济性分析,然而由于经济性分析是否合理、公正直接影响冰蓄冷的推广,因此需要建立一个公正合理的模型对冰蓄冷工程进行经济性分析。论文对冰蓄冷空调的设计施工优化及经济性比较方面作了大量的研究。在对我国的能源现状及冰蓄冷在国内外的发展现状进行调查研究的基础上,针对某银行办公楼空调方案设计,分析了各种制冷方式的特点,进行冰蓄冷工程的设计;建立冰蓄冷工程经济性评价的数学模型,分析该冰蓄冷工程的初投资与运行费及主要经济性参数,提出了公正的冰蓄冷工程经济性分析思路;深入探讨了影响冰蓄冷经济性的因素,以提高工程的经济效果;论文对对冰蓄冷空调的未来发展进行展望并提出建议。
【Abstract】 Thermal storage technology is a technology that use electricity to drive refrigeration system at night at that time when the electricity price is cheap. Cold energy stores in thermal materials such as water or ice.When in the daytime, we get the cold capability stored in the thermal materials being released to meet the requests of air-condition system or production technics.Now, static ice cold thermal storage technique is widely used in our country.In this paper, many problems which exist in the field of designing ice thermal storage systems were taken into account. Problems were found that many designers were ambiguous about the design method and can not break away from traditional design concepts which led to conservative design and could not show the superiority of the thermal storage technology. As we know, popularize of this technology depends on economic analize, economic efficiency directly impact on the application of the technique.Therefore, we must build up a fair and reasonable module which fits to ice thermal storag e system.A large number of research work were done about reasonable design and economical comparison. In the basis of investigate the present situation of this technology,a design of the air-condition plan of a bank building was made. Characteristics of various refrigeration methods were analyzed, mathematics model of economical evaluation was established, economical parameters of preliminary investment and operation expenses were researched, a train of thought about ecnomical analysis was proposed, the factors which influence economics of this technology were deeply confered to improve economical effects of the project. Finally, some suggestions were brought out and prospections of this technology was carried out.
