摘要
阐述了蓄冷空调系统常用的三种控制方式的特点 ,分析了在优化控制下 ,现有方法在选择制冷机、蓄冷设备容量时所存在的问题。以优化控制为基础 ,不仅考虑了系统全年运行费最少而且考虑了整个蓄冷系统的初投资 ,以系统投资回收期最短为原则 ,为蓄冷空调系统提出一种综合经济性最佳的方案———优化方案。编制了软件optcon来确定优化方案 ,此软件能给出蓄冷槽和制冷机所应承担的动态冷负荷。通过对一实例进行模拟分析表明
Features of three common control strategies for cold-storage air-conditioning system are presented. Problems of present method to calculate capacities of chiller and cold-storage tank under optimal control are analyzed. Based on optimal control, considering not only operating cost, but also the global economics of whole cold-storage system, a method and software to design optimal scheme is proposed. The simulation result shows that the optimal scheme is the most economics among common cold-storage schemes through a case study.
