回路控制法——新的空调变频水系统控制方法

Loop Control Method——New Control Strategy Of Air-condition Variable Frequency Water Systems

分析比较了空调水系统中定末端压差控制和最小阻力控制方法的优缺点,结合基本回路方法提出了能够解决这些缺点的新的控制方法——回路控制法,通过MATLAB软件计算表明这种控制方法能够很好地解决管网水系统的解耦问题,明确了新的控制方法的节能及调节质量优于原有方法。

The constant terminal differential pressure control and the minimum resistance control were analyzed and compared.Based on the basic loop method,a kind of new control strategy——loop control method that can solve these problems was put forward.Through the MATLAB calculation,the result indicates that this strategy can solve the water pipeline coupling problem very well and also shows that the energy saving effect and accommodating quality of the new method have obvious superiority to primary ones.
