摘　　要： 研究了冰蓄冷系统对电网和电力部门的贡献,即冰蓄冷系统的正外部性;提出了由于采用冰蓄冷系统,给电力部门带来的碳减排量的方法论;并对浙江省某办公建筑的典型冰蓄冷系统进行了分析.结果表明,冰蓄冷系统的应用可提高电网负荷率,使电力部门实现减排;此办公建筑的典型冰蓄冷系统的单位蓄冷量的碳减排量为0.686 kg.kWh-1;2006年空调期,华东电网的电网负荷率每变化1%,供电煤耗变化量为4.982g.kWh-1.另外,碳减排量可用作评价冰蓄冷系统对电网的贡献,即冰蓄冷系统正外部性的一个指标. The contribution of ice storage system to the power grid and electricity sector,that was,the positive externalities of ice storage system was studied.A methodology was presented to calculate the carbon dioxide emissions reduction caused by the utilization of ice storage system.Further,the typical ice storage system in an office building in Zhejiang province was analyzed.The results show that the utilization of ice storage system can improve the power grid load factor so as to enable the electricity sector cut emissions.And,carbon dioxide emissions reduction per unit of storage capacity for the typical ice storage system is 0.686 kg·kWh-1.In the cooling periods of 2006,every time the load factor of East China power grid varied 1%,the variation of coal consumption of power supply was 4.982 g·kWh-1.In addition,it＇s proposed that carbon dioxide emission reductions can be used as an indicator to assess the contribution of ice storage systems to power grid.
