【摘要】：本文提出了冰蓄冷空调低温送风系统新的设计方法和思路以及控制卸载技术的优越性,对冰蓄冷空调低温送风系统进行了较为深入的研究,以工程项目为实例,对动态冰蓄冷低温送风系统和冷水机组是否采用控制卸载技术进行了经济性分析。1、对供冷区域所需新风量以及冷负荷进行了详细的计算,并对冰蓄冷低温送风空调中冷水机组的选型、辅助设备的确定以及自动控制系统的选择作了深入的研究和分析。2、考虑到风管周围空气露点温度,对末端设备的选型和布置作了阐述和分析。并着重探讨了冷水机组控制卸载技术与蓄能空调供冷优化配置的研究,指出只需增加一套自控软件既可实现在冰蓄冷的基础上进行二次移峰。3、通过建立数学模型,对冰蓄冷低温送风空调进行了比较完整的经济性评价,并介绍了静态投资回收年限分析法、动态投资回收年限分析法、寿命周期分析法三种方法,并对系统中涉及的初期投资额、年运行费用、维护费用等参数进行了分析。4、以厦门汇金国际金融大厦为工程实例,并在100%空调设计日负荷下作为运行模式,分别对常规空调供冷、分量蓄冰供冷、全量蓄冰供冷三种运行工况进行经济性对比分析,并在此基础上绘出峰谷电价比与回收年限趋势图。以及以山东省淄博市某商场为工程实例,对其是否采用冷水机组控制卸载技术进行经济性分析。
[Abstract]:In this paper, a new design method and idea of low temperature air supply system for ice storage air conditioning system and the superiority of control and unloading technology are put forward. The low temperature air supply system of ice storage air conditioning system is studied in depth, taking the engineering project as an example. The economic analysis of whether the dynamic ice storage low temperature air supply system and the chiller adopt the controlled unloading technology is analyzed. The fresh air volume and the cooling load in the cooling area are calculated in detail. Furthermore, the selection of chiller, the determination of auxiliary equipment and the selection of automatic control system are studied and analyzed in detail, considering the dew point temperature of the air around the air duct. The selection and arrangement of terminal equipment are described and analyzed. The research on the control and unloading technology of chiller and the optimal configuration of energy storage air conditioning system is emphasized. It is pointed out that only one set of automatic control software can be added to realize the secondary peak shifting on the basis of ice storage, and the mathematical model is established. The economic evaluation of ice storage low temperature air conditioning system is carried out, and three methods, static investment recovery life analysis, dynamic investment recovery life analysis and life cycle analysis, are introduced. The initial investment, annual operating cost, maintenance cost and other parameters involved in the system are analyzed. 4. Taking the Huijin International Financial Building in Xiamen as an engineering example, and taking the daily load of 100% air conditioning design as the operation mode, On the basis of the comparison and analysis of the operation conditions of conventional air conditioning, component ice storage and total ice storage, the trend of peak and valley electricity price ratio and recovery life is drawn. Taking a shopping mall in Zibo City, Shandong Province as an engineering example, the economic analysis on whether the chillers are used to control the unloading technology is carried out.
