摘要:

大型船用设备长时间工作会出现过热现象,需要建立冷却系统,保证设备在安全温度范围内工作.为满足某大型船用设备冷却要求,基于FloMaster仿真平台,构建海水冷却系统仿真模型,开展动态工况的仿真研究.根据换热器前后冷却液(乙二醇溶液)的温度,改变泵的转速或阀门开度,实现海水流量的自动控制.提出3种有效控制方案,利用FloMaster-Simulink联合仿真方法,计算得到变工况下系统的响应特性和运行特点.结果表明:开环和闭环共同作用,同时控制泵的转速时,冷却系统控制效果最优,能耗较小,为实际冷却系统工程问题提供了参考.

Abstract:

Large-scale marine equipment will overheat if it works for a long time and a cooling system is necessary to be established to ensure that the equipment works in a safe range of temperature. To meet the cooling requirements of a large-scale marine equipment, a model of seawater cooling system is established in FloMaster, and simulations under dynamic conditions are conducted. According to the temperature of the coolant (glycol solution) in the front or back of the room of the heat exchanger, the pump speed or valve opening is changed to realize automatic control of seawater flow. Three control schemes are proposed, and the control effects are evaluated by the response characteristics and operating characteristics of the system under variable working conditions using the FloMaster-Simulink co-simulation method. The results show that when the pump speed is controlled by both the open loop and closed loop, the best control effect and lower energy consumption can be achieved.

Key words: cooling system, FloMaster-Simulink, dynamic simulation, scheme optimization
