摘　　要：基于一种分散式二次泵系统,从改变管网动力分布的角度,对区域空调输配能耗进行节能研究。在设计工况、部分负荷、不同负荷空间分布形式的情况下,通过对分散式二次泵系统的水泵总功率的计算,并与传统的集中式二次泵系统相比较,研究动力分布与负荷分布对于分散式二次泵系统的输配节能影响。结果表明:二次泵的分散布置可以有效减小系统输配能耗,在中高负荷率下,节能效果更加明显。分散式二次泵系统输送能耗与负荷空间分布形式有关,负荷集中于管网最近端时系统节能率最高。Based on a distributed secondary pump system, energy saving research on district air conditioning transmission and distribution energy consumption is carried out from the perspective of changing the power distribution of the pipeline network. In the case of design conditions, partial load, and different load spatial distribution, the impact of the power distribution and load distribution on the energy distribution of the distributed secondary pump system are studied by calculating the total pump power and comparing it with the traditional centralized secondary pump system.The results show that the decentralized arrangement of the secondary pump can effectively reduce the energy consumption of the system. At medium and high load rates, the energy saving effect is more obvious. The energy consumption of the distributed secondary pump system is related to the spatial distribution of the load. When the load is concentrated on the nearest end of the network, the system has the highest energy saving rate.
