摘　　要：在分析空调系统变流量运行调节的基础上,提出了变温差控制并给出了控制方案。变温差控制过程不仅具有负反馈,而且具有正反馈,能较好的适应空调负荷的变化。比较分析了变温差控制、定温差控制、定压差控制的节能性,变温差控制的节能潜力最大,是一种最佳控制方式。Variable temperature difference control and control scheme are put forward based on the operation regulation analysis of variable flow control of air conditioning chilled water.Not only negative feedback but also positive feedback being included,it can be fitted to the change in air-conditioning load well.It is an optimal control and the potential of energy conservation of variable temperature difference control is supreme compared to constant temperature difference control,and constant pressure difference control.
