Control strategy analysis of ice cool storage air conditioning system in an office building in Beijing
摘要：
从节能及碳排放的角度分析了北京市某办公楼冰蓄冷空调系统的控制策略。比较了无蓄冷、冰蓄冷承担基础负荷+基载主机调峰、基载主机承担基础负荷+冰蓄冷调峰3种运行模式。结果表明：冰蓄冷承担基础负荷+基载主机调峰的方式可实现运行成本的最大节约，但碳排放量会超出限制要求；基载主机承担基础负荷+冰蓄冷调峰的方式经济效益显著，且碳排放量可满足限制要求。
Abstract：
Analyses the control strategy of ice cool storage air conditioning system in an office building in Beijing from the perspective of energy saving and carbon emission. Compares the three operation modes of conventional, regulation of basic load by ice cool storage unit plus peak load by base chiller, regulation of basic load by base chiller plus peak load by ice cool storage unit. The results show that the way of basic load by ice cool storage unit plus peak load by base chiller can minimize the operating costs, but the carbon emissions will exceed the limit requirements; the way of basic load by base chiller plus peak load by ice cool storage unit has significant economic benefits, with the required carbon emission limit.
