摘　　要：为了实现中央空调系统的节能,对大楼的空调冷却塔运行性能进行了测试。通过对制冷机冷却水出口温度、冷却塔出口水温和室外气象参数的观察记录,由冷却塔效率计算公式求得冷却塔的效率。测试发现,该大楼冷却塔效率整体偏高,主要是因为风机功率偏大保证了较高的气水比。最后分析了对冷却塔效率的影响因素,提出了改造建议。In order to improving energy efficiency of central air-conditioning system, the performance of cooling towers in Shenzhen Office Building has been tested. Based the records of cooling water outlet temperature, the outlet water temperature and outside weather parameter, the efficiency of the cooling towers could be calculated by the formula. For the greater power of the fans guaranteed the high ratio of air and water, the cooling towers has high efficiency. At the same time, the impacts of cooling tower＇s efficiency were analyzed and some advices were presented to improve the cooling tower＇s efficiency.
