不同蓄冷率冰蓄冷空调系统经济性分析——以深圳某商业办公楼为例

冰蓄冷空调系统以优良的平衡峰谷电力负荷能力和较低的运行费用备受推崇,应用越来越广。以深圳某商业办公楼为例,以投资回收期为评价指标,利用静态评价法,通过计算不同蓄冰率对应的初投资、运行费用从而得出不同蓄冰率与投资回收期的关系。结果表明基于主机优先运行策略所计算的理论蓄冰率对应的投资回收期最短;不同地区不同类型的项目可参考本文计算方法具体问题具体分析。

Economic Analysis of Ice Storage Air Conditioning System with Different Storage Rate

Ice-storage air conditioning system is praised highly as its excellent balancing electric load capacity and lower operation cost.The static evaluation method is utilized.Meanwhile, the relationship between the ice-storage rate and the pay-back period based on the calculation of the initial cost and operation cost is concluded by taking an actual project in Shenzhen.The result indicates the pay-back period corresponding to the theoretical ice storage rate based on the operation strategy of chill priority is the minimum, and various types of projects in different area needs to be studied in details referring to the research method in this article.
