摘　　要：本文讨论采用TR算法对北京市某绿色建筑变风量空调系统进行变静压控制。TR算法通过对变风量空调末端风阀开度和风量的监控实时调整管道静压设定,保持至少一个末端风阀接近全开,最大程度的降低管道阻抗,减少风机做功。一年的测试结果显示,TR算法与该建筑原有总风量法相比实现风机节能15%,并且保持同等室内舒适度。This paper discusses the application of Trim and Respond(TR) algorithm for resetting static pressure setpoint of a variable air volume(VAV) system in a green building in Beijing. The TR algorithm adjusts the static pressure setpoint through real-time monitoring of damper opening and air volume of VAV terminal units and remains at least one VAV damper at nearly fully open position to minimize the pressure resistance of the ductwork and save fan energy. According to the one-year testing results, the TR algorithm saves 15% of fan energy with the same level of thermal comfort, compared to existing total air volume control of the building.
