摘要
夏季不同性能曲线的冷水机组联合使用的运行策略会对系统能耗产生重要影响,寻找最优的运行方案是实现系统节能的关键步骤之一。基于系统能耗模型和寻优目标函数,借助计算机辅助编程,建立了不同性能曲线的机组组合在不同运行策略下最小能耗与运行成本的计算方法,并对某实际工程进行了案例分析。结果表明,设计合适的运行策略能为不同冷水机组的联合运行带来良好的节能效益。
The operating strategy for multiple chillers with different performance curves operating in combination in summer may have influences over system energy consumption. In this paper, a computer - assisted calculation method based on energy consumption model and optimization objective function for finding the optimal solution of minimal energy consumption and operation costs is established. Then a practical case is analyzed and the results Show that an appropriate control strategy for multiple chillers operating in combination can provide excellent performance benefits.
