摘要
变风量系统由于其可观的节能效果在大型商务建筑中得到日益广泛的应用。应用日见广泛的直接数字控制器及集成楼宇控制系统(BMS)大大地提高了空调系统的检测及监控,这也为空调系统在系统层次上的优化控制奠定了基础。本文提出了变风量系统的送风静压和送风温度优化控制方法以及多区域新风量优化控制方法。这些控制方案及控制程序在VAV空调系统的动态仿真平台上进行测试以评估它们的动态控制性能、节能及空气品质特性。
Variable Air Volume （VAV） systems are widely used nowadays because of the great potentials in energy savings. Widely used Direct Digital Controllers （DDC） and integrated Building Management Systems （BMS） improve the measurement and monitoring of air conditioning systems. They also provide sufficient information for supervisory optimal control at the system level. The strategies of supply air static pressure optimization and supply air temperature optimization are presented. Additionally, the optimization strategy of fresh air flow rate in multi-zone air conditioning systems is also presented. These strategies are validated in a ＂living＂environment of dynamic simulation platform of VAV air conditioning systems in term of dynamic control characteristics, energy performance as well as environmental performance.
