摘　　要：采用一种新的变静压控制法——修剪与响应法对北京市某绿色建筑变风量空调系统控制方法进行了优化。修剪与响应法通过读取和计算变风量末端需求信号来优化调整管道静压设定值,空气处理机组风机自动变频,维持静压设定值,以保证至少一个空调末端风阀接近全开,使风系统阻力最小。对比分析了供暖季总风量法和变静压法下系统的运行情况,结果表明,采用后者,在不影响房间舒适度的情况下,风机节能12.6%。Adopts a new variable static pressure control method--trim and respond （TR） method and optimizes the variable air volume （VAV） system of a green building located in Beijing. By measuring and calculating the requests from the terminal units, optimally adjusts the set value of the pipe static pressure and the fan of air conditioning unit automatic frequency conversion as well as maintains the set value in order to ensure one air valve fully opened at least and to minimize the resistance of the air system. Compares and analyses the operating conditions of total air volume in a heating season and variable static pressure. The result shows that the energy saving of the fan is 12.6% under the latter mode, with the same thermal comfort.
