Research on Energy Efficiency Improvement Method of Existing Central Air-conditioning Cooling Water System

面对当前既有建筑高能耗的现状,国内外已有大量针对既有集中空调冷却水系统能效提升的研究,但大量的研究都局限在理论的层面,与系统的实际运行出现了脱节,在实际项目中应用受限。为了进一步提升既有建筑集中空调水系统运行能效,在集中空调冷却水系统多年现场测试和空调设备性能探索的基础上,针对既有公共建筑集中空调冷却水系统在设备性能诊断、设备性能优化及提升、设备优化组合运行、系统运行参数监测、能效整体优化提升等方面进行了深入理论研究,提出了一种简化、高效的能效提升方法及控制逻辑。

Faced with the current situation of high energy consumption of existing buildings,there have been a large number of researches on improving the energy efficiency of existing central air-conditioning cooling water systems at home and abroad,but a large number of researches are confined to the theoretical level,which is disconnected from the actual operation of the system,and their application in practical projects is limited.In order to further improve the operation energy efficiency of the existing building centralized air-conditioning cooling water system,On the basis of many years of field testing of central air-conditioning cooling water system and exploration of air-conditioning equipment performance,this paper conducts in-depth theoretical research on equipment performance diagnosis,equipment performance optimization and improvement,equipment optimization and combined operation,system operation parameter monitoring,overall optimization and improvement of energy efficiency of central air-conditioning cooling water system of existing public buildings.A simplified and efficient energy efficiency improvement method and control logic are proposed.
