摘　　要：针对螺杆冷水机组高精度和低成本两者无法同时兼顾的的问题,对螺杆冷水机组的控制方法进行试验研究,解决了现有螺杆冷水机组控制技术中高精度和低成本无法同时兼顾的难题。在实现螺杆冷水机组低成本、高可靠性的同时,实现了被控水温精度高达±0.3℃的高精度。According to the problem that both high precision and low cost of screw chillers can not be taken into account,through carries experimental research on the control method of screw chiller,solves the problem that high precision and low cost cannot be taken into consideration in the control technology of the traditional screw cold water unit.While achieving low cost and high reliability of screw chillers,also realizes the controlled water temperature accuracy is as high as±0.3 degree.

关 键 词：螺杆冷水机组 高精度 低成本
