摘要
针对变风量空调系统,采用LonWorks现场总线技术,分别运用PID控制方法和串级控制方法对变风量空调系统的送风温度和回风温度进行了控制,以某一空调房间温度控制为例,通过实验对两种方法进行了对比,结果表明串级控制能够取得更好的控制效果。
The control method of the supply-air temperature and the indoor temperature in variable air volume system is studied separately applying temperature cascade control and temperature PID control method based on LonWorks fieldbus technology. Using these two methods the on - line temperature control of a air - conditioning room is realized. These two methods are compared through experimental results. The result shows that cascade control method is more effective.
