摘　　要：本文首先介绍了分布式变频泵供热系统的基本原理,并比较了传统供热系统与分布式变频泵供热系统运行方式与特点。介绍了零压差点的概念与作用,并基于内蒙古工业大学实验平台,采用变压差调节法使分布式变频泵供热系统达到水力平衡,即运行流量达到实际需求的流量,对数据进行综合分析,确定零压差点出现的最节能位置,保证系统供热量与稳定性。This paper first introduces the basic principle of distributed variable frequency pump heating system, and compares the operation mode and characteristics of traditional heating system and distributed frequency conversion pump heating system. This paper introduces the concept and function of zero pressure difference point. Based on the experimental platform of Inner Mongolia University of Technology, the variable frequency difference regulation method is adopted to reach the hydraulic balance of the distributed variable frequency pump heating system, that is, the operation flow rate reaches the actual demand. The data is analyzed synthetically to determine the most energy-efficient location of zero pressure difference point and ensure the heat supply and stability.
