摘要
控制空调房间的设定温、湿度且使能耗最少是研究者关注的重要问题。文中以某一空调房间的变水量自动控制为例,分析了变水量空调系统的动态特性,研究了水流量变化、加湿量变化对房间温湿度的影响,分析模拟了PI控制参数的选取对控制过程影响进行。模拟结果显示合理的控制参数能实现较好的控制精度。
The control of temperature and moisture in an air conditioning room with less energy consumption has been paid attention by researchers.Reasonable control parameters＇ selection can not only control temperature and humidity in high precision,but also save energy.In this paper,the dynamic behavior of variable water volume（vwv） air conditioning system was analyzed.Effects of water flow rate and humidified rate on the room＇s temperature and moisture were studied.The selection of the parameters for a PI control system was simulated.The results showed that the reasonable control parameters can increase the control precision.
