集中空调冷却塔节能分析与探讨
Energy saving analysis and discussion of cooling towers of central air conditioning systems
摘要：
随着集中空调节能技术的发展，关于冷水系统的节能方案和控制策略已趋于统一，而冷却水侧冷却塔的节能空间仍存在争议。为进一步提高集中空调的节能率，从理论和实际应用两方面分析了冷却塔开机台数和风机运行频率对冷水机组性能乃至整个集中空调系统能耗的影响，得出通过对冷却塔的优化控制可使集中空调节电率提高5%的结论。
Abstract：
With the development of the central air conditioning energy saving technology, energy saving schemes and control strategies of chilled water system tend to unify, but the energy saving space of the cooling tower in cooling water side remains controversial. Striving to further improve the energy saving ratio of central air conditioning systems, from the aspects of theory and practice, expounds the influences of operating numbers of cooling towers and operating frequency of fans on the performance of chillers and the energy consumption of the whole central air conditioning system. Concludes that through the optimization control of cooling towers, the power saving ratio of the central air conditioning system increases by 5%.
