摘　　要：本文针对传统水源热泵多联机系统供回水温差小、循环能耗大的弊病,以某应用项目为例,提出了采用分布式混水泵的水源热泵多联机系统,分析了该系统的管件构成、运行控制机理和年运行节能量,并进行了经济性比较。结果显示:该系统与传统水源热泵多联机系统相比,节能率高达6.27%,投资回收期约为4.5 a。In view of the disadvantages of the traditional water-source heat pump multi-split system,such as small temperature difference between supply and return water and large circulation energy consumption,taking an application project as an example,this paper proposes a water-source heat pump multi-split system with distributed mixed water pumps.The pipe fitting composition,operation control mechanism and annual operation energy saving of the system are analysed,and the economic comparison is made.The results show that compared with traditional water-source heat pump multi-split system,the energy-saving rate of this system is as high as 6.27%,and the payback period of investment is about 4.5 years.
