分析了冰蓄冷系统的冷机优先、蓄冰罐优先和优化控制三种控制策略，提出了优化控制的目标和约束，并以某建筑为例对比分析冰蓄冷系统在优化控制策略和冷机优先控制策略下的运行费，阐明优化控制可以发挥现有系统潜力，更有效地削减电负荷高峰。 This paper analyzes the three control strategies of the ice storage priority, the ice storage tank priority and the optimal control of the ice storage system, proposes the objectives and constraints of the optimization control, and compares and analyzes the ice storage system in the optimization control strategy and the cooling priority with a certain building as an example. The operating costs under the control strategy clarified that the optimized control can leverage the potential of the existing system and reduce the peak of electric load more effectively.
