摘要
以实际建筑空气源热泵中央空调系统为对象,试验研究了一种室内外温度协同的供水温度优化控制策略,并分析讨论了控制策略的实际应用价值。室内外温度协同优化控制策略耦合了室外温度线性前馈控制过程和室内温度PI反馈控制过程。试验结果表明,夏季室外温度28~36℃条件下,室内外温度协同控制策略具有很好地室内温度的控制效果,平均绝对温度偏差为0.09℃,最大温度偏差仅0.4℃,同时具有显著的节能效果,相比于基本控制策略节能率达到31.14%。试验过程表明,该策略算法计算量小,很容易在常规温控设备中实现,可在小型空气源热泵中央空调系统应用。
Taking the air source heat pump(ASHP)integrated central air-conditioning system of an actual building as the object,an optimal control strategy for supply water temperature with cooperative indoor and outdoor temperature is experimentally investigated,and the practical application value of the control strategy is analyzed and discussed.The indoor and outdoor temperature cooperative optimal control strategy is coupled with the outdoor temperature linear feedforward control process and indoor temperature PI feedback control process.The experimental results show that under the condition of outdoor temperature 28-36℃in summer,the indoor and outdoor temperature cooperative control strategy has a good control performance on indoor temperature.The average absolute temperature deviation is 0.09℃,and the maximum temperature deviation is only 0.4℃.At the same time,it has significant energy saving effect,and the energy saving rate reaches 31.14%compared with the basic control strategy.The experimental process shows that the algorithm has a small amount of calculation and is easy to implement in conventional temperature control equipment,which can be applied to small-scale ASHP integrated central air-conditioning systems.
