摘要(Abstract):

提出了冷机出水温度优化控制策略,对被控温度进行优化设定,使系统能够调整优化以适应负荷和室外气象条件的变化。并在建立的冰蓄冷系统仿真器的基础上,对该温度的优化控制策略进行了试验验证,比较了恒定设定控制和优化控制对整个系统能耗及稳定性的影响。
An optimal strategies is presented to reset the control according to the variations of indoor and outdoor loads. The optimal strategies are tested and validated based on simulation platform of ice-storage air conditioning system, and compared with the conventional strategy of fixed set-point to result in the performance of energy use and control stability.
