武汉光谷生物城九峰创新基地水蓄冷空调系统运行策略及经济性分析

摘要

Based on the general situation of the project,cooling load characteristics and cooling characteristics with large temperature difference (4 ℃/12 ℃)from the energy station,discusses the necessity of transformation of the chilled water storage air conditioning system.Presents the transformation scheme of the chilled water storage air conditioning system,and provides the operation modes and operation strategies of the chilled water storage air conditioning system based on the analysis of hourly cooling load of the design day.The economic comparison with conventional air conditioning system shows that the chilled water storage system can transfer 41.22% of the non-off-peak electricity power,and reduce operating electricity costs about 1.671 million yuan per year.%根据工程概况、冷负荷特点及能源站大温差（4℃／12℃）供冷的特点，阐述了进行水蓄冷空调系统改造的必要性。介绍了水蓄冷空调系统改造方案，并在分析逐时冷负荷的基础上，提出了水蓄冷空调系统的运行模式和运行策略。与常规空调系统的经济性比较表明，采用水蓄冷空调系统能转移41．22％的非低谷电量，年运行电费可减少167．10万元。
