摘要 从热力学、流体力学和传热传质的基本原理出发 ,以TRNSYS为仿真平台 ,建立了冷却塔动态数学模型 ,并对其进行了实验验证 ,结果表明辨识参数较准确时 ,仿真结果精度较高、可靠性较好 。 Based on the principle of thermodynamics, hydromechanics and heat and mass transfer, taken TRNSYS as the simulation platform, presents the dynamics mathematical model of cooling tower and validates it by experiment. The results show that the model has high accuracy and reliability when the identification parameters are accurate. It is suitable for system simulation.
