摘要
冰蓄冷空调系统可以平衡电网压力,达到"移峰填谷"的作用,为了推广冰蓄冷空调的使用,提高系统的经济效益和节能效果具有重要意义.通过建立冰蓄冷空调系统的运行模型,表示出冰蓄冷空调系统的日运行费用和日运行能耗.通过TRNSYS软件对目标建筑的模拟得到目标建筑冷负荷.依据目标建筑冷负荷,设定系统制冷主机每小时的荷载率,建立冰蓄冷空调系统节能、经济运行的多目标函数模型,并使用粒子群算法对模型求解得到系统优化运行参数.通过实例分析:与现阶段的运行策略相比较,使用得到的优化运行参数指导系统运行可以为用户节约10.2%的运行费用,同时可以降低15.2%的电能损失.
Ice-storage air-conditioning system can balance the grid pressure to achieve“peak load shifting”effect.In order to promote the use of ice storage air-conditioning,enhancing economic efficiency and energy-saving effect of the system is important.Through the establishment of ice storage air-conditioning system operation model daily running costs and daily energy consumption of ice-storage air-conditioning system can be obtained.By using TRNSYS simulation software on the target architecture,building cooling load can also be obtained.Based on the target building cooling load,setting the system chiller hourly load rate,establishing energy-saving and economical operation of the system of multi-objective model,and using the particle swarm algorithm to solve the model system,optimal operation parameters as thus acquired.An example:Compared with operation strategy at this stage,using the optimized operating parameters guide system operation can save 10.2%of the operating costs and reduce 15.2%of the energy losses.
