摘　　要：大型试验中心冷源集群系统作为一种新型的制冷空调产品性能试验装置的后台供冷系统,其减振防噪措施是否合理是系统高效运行的前提。本文从振源和系统管网两个方面介绍减噪减振设计优化方法。通过设计一款高效的水泵减振器来规避振源处带给系统的影响,经使用发现其隔振效率可以达到98%以上。此外,在分析系统中水锤产生的基础上,理论计算水锤吸纳器最小容量及在现实使用时应该放大一号的结论。末端气动蝶阀启闭是大型试验中心冷源集群系统中发生水锤现象的主要原因,本文对比工程中使用的各规格管道,得出较合适启闭时间,从而为类似工程做参考。The large test center of cold sources cluster system as a new type of cold supply system in background for refrigeration and air-conditioning product performance testing device, if its measures of anti-noise and shock absorption is reasonable, the system will operate efficiently. The design optimization method of anti-noise and shock absorption is introduced from two aspects of vibration source and pipe network system. The influence of vibration source on the system is avoided by designing an efficient water pump shock absorber, the result is that the vibration-isolation efficiency can achieve more than 98% by using it. Besides, On the basis of the analysis of water hammer causes, theoretical calculation of the minimum capacity of water hammer absorption device is made, and the conclusion that a design value should be bigger size than the theoretical value in practical application is proposed. Pneumatic butterfly valve opening and closing is the main cause of water hammers produced in a large test center cold source cluster system, the appropriate time of its opening and closing is determined by comparing Various specifications of the pipes used in project, so as to make reference for similar nroiects.
