摘要
全年运行的单冷空调系统是按照夏季工况进行设计的 ,当偏离设计工况后 ,机组运行会受到一定影响。本文通过安置在冷凝器集液管上的温度传感器作为发信设备 ,充分考虑该点温度变化率在实际控制中的作用 ,应用模糊控制方法实现了在冬季对双螺杆单冷机组运行工况的实时控制 。
Year-round running air-cooled chillers are designed according to summertime condition. When the units operate at far away from designed condition they can not run well. In the paper it is introduced that when twin-screw air-cooled chiller unit runs in winter the operating condition is controlled by fuzzy controller, during which the rate of change of the temperature measured by the sensor what is put on the condensed liquid pipe is considered. The controlling results are satisfied.
