摘要

随着数据中心绿色发展及日趋严格的电能使用效率限值，小型液冷装置已逐渐成为小型高密度数据中心散热的新选择，同时为余热利用提供了新的有利条件。在小型数据中心余热负荷范围内，对3种水源热泵系统在余热工况下的能效特性进行对比分析。结果表明：源侧提升、输配侧提升、用户侧提升水源热泵系统能效分别分布于5~7、5~6、4.5~6.5；当用户侧热负荷需求在0~1 750 kW和2 500~3 200 kW时，源侧提升水源热泵系统能效最高，在1 750~2 500 kW时，源侧提升与输配侧提升水源热泵系统能效相近；最后得到用户侧热负荷需求与数据中心余热负荷间的耦合匹配关系

，

的取值范围为1.196 2~1.364 2。

Abstract

The power usage limit becomes lower with the green development of data centers. The small liquid cooling device is emerging as a new cooling option for small data centers with high energy density

which helps recover the waste heat. In this paper

the energy efficiency characteristics of three types of water-source heat pump systems under different surplus heat conditions are compared and analyzed in the surplus heat load range of small data centers. The energy efficiency of the water-source heat pump system is distributed at 5-7

5-6

and 4.5-6.5 on the source side

transmission and distribution side

and user side

respectively. When the user-side heat load is retained at 0 kW to 1 750 kW and 2 500 kW to 3 200 kW

the energy efficiency of the source-side enhanced water-source heat pump system is highest. When the user-side heating load demand is 1 750 kW to 25 00 kW

the energy efficiency of the source-side enhanced water-source heat pump system is near that of the transmission and distribution-side enhanced water-source heat pump system. Finally

the coupling matching formula

is obtained between the user-side heat load demand and data center surplus heat load

in which

ranges from 1.196 2 to 1.364 2.
