摘要
本文通过一种新风优化控制策略:基于预测的多区域VAV空调系统末端再热控制策略,以解决多区域新风的分配问题。该控制策略在预测负荷、找出使系统节能最大的最优新风比的基础上,研究再热器性能,得到各区再热器电压和优化的预热时间。该策略在不影响室内空气品质和舒适性的前提下,以实现能耗最小为目的,来分配区域的新风量。仿真分析的结果显示,优化预热时间的末端再热控制具有较好的适应区域新风量变化的能力,并具有一定的节能潜力。
A new outdoor air optimal control strategy that is based on prediction is presented to solve outdoor air distribution in multi-zone. The load and outdoor air demand in different zones can be predicted, and then the optimized outdoor air ratio is obtained. The optimized preheat time of terminal-reheaters are obtained to satisfy the requirements. The simulation result shows that the control strategy controls outdoor air distribution very well and has comparative energy saving potential.
