| 摘 要： | 变风量(VAV)空调系统具有节能、空气品质高的特点,应用前景广阔.建立VAV空凋系统动态模型并进行仿真,对研究VAV空调系统的动态特性具有重要意义.引入容性环节与阻性环节相结合的方法,对VAV空调系统的关键部件进行更为合理的划分,解决了各部件模块间的可连接性问题;从对象工作机理出发,将各风道连接处的部件抽象为节点容积模型,从而简化了建模仿真的复杂度,提高模块的可重用性.利用所建模型对VAV空调系统的动态特性进行了仿真研究,计算结果证实了模型的有效性,并且可以满足实时动态仿真的要求,可以作为各类空调风系统仿真的参考模型.

| Abstract: | A VAV air conditioning system dynamic model is developed,which is important in studying the dynamic behaviors of VAV.By introducing the technique of combining the drag model with volume model,a more reasonable model dividing method was proposed.Thus the models were easier to connect.Based on the mechanism of pipe grid,the connection point between the air pipes was lumped as a volume node model.Subsequently,the complexity of air conditioning system model was alleviated.Dynamic responses of VAV were numerical... |
