区域型冰蓄冷夏季空调系统运行策略优化分析

Optimization Analysis of Operation Strategy of Regional Ice Storage Air Conditioning System

研究了区域能源系统夏季供冷运行原理及模式,进行了夏季蓄冰优先、机组优先和非蓄冰三种运行模式下的模拟对比分析,得到在负荷率分别为100%、80%、50%和20%时的经济和能耗对比。能耗和运行费用来看,夏季机组优先运行与非蓄冰运行模式差别甚微,而蓄冰优先运行模式相比于非蓄冰运行,节约运行费占比11.77%,单位电耗费用降低24.05%。合理运用冰蓄冷技术,能够显著降低系统运行费用,为用户带来良好的经济效益。

The principle and mode of summer cooling operation of regional energy system were studied.The simulation comparison analysis of summer ice storage priority,unit priority and non-ice storage was carried out.The load rates were 100%,80% and 50% respectively.Compared with the economy and energy consumption at 20%.The principle and mode of summer cooling operation of regional energy system were studied.The simulation comparison analysis of summer ice storage priority,unit priority and non-ice storage was carried out.The load rates were 100%,80% and 50% respectively.Compared with the economy and energy consumption at 20%.In terms of energy consumption and operation cost,there is little difference between unit priority operation mode and non-ice storage operation mode in summer.Compared with non-ice storage operation mode,regional energy system under ice-storage priority operation mode saves 11.77% of the operation cost and reduces 24.05% of the unit power consumption cost.Reasonable use of ice storage technology can significantly reduce the operating cost of regional energy system and bring good economic benefits to users.
