摘　　要：本文对普遍使用的一次泵、末端变流量、冷水机组定流量的空调冷冻水系统与冷却水系统的流量进行了理论研究,从理论上解释了在非满负荷情况下,水系统调节中出现的流量大于理论值的现象,表明出现这一问题并非是设计时泵的扬程和流量的选型不恰当,而是系统在变负荷调节时自我调节的必然结果。本文还探讨了出现大流量、小温差时对系统的影响,提出了减小这一问题的解决方法。This paper theoretically researched the common used air-conditioning with primary pump and terminal variable flow control and the flow of invariable chilled-water refrigeration systems,and theoretically explained that when the number of the running units reduces,the phenomenon of large flow and little temperature difference still big although the right selection of the chilled-water pumps and cooling water pumps and the proper design of the systems.Then,this paper discusses the problems result from oversize water flow,and some related suggestions and solutions were proposed.At last,the paper investigated the impact on the system by the phenomenon and gave some advises to resolve this problem.
