摘　　要：以严寒地区某小区为例,采用回水温度一致法,通过远传电动调节球阀对小区二次网水力平衡进行调控,抽样采集用户室温,分析回水温度对系统室温的影响。通过大量室温数据统计分析,采用标准差、方差及热力平衡度来衡量系统室温一致性。测试结果表明,采用自动算法进行平衡调控,效果优于人工调控。当各楼栋回水温度趋于一致时,二次网系统水力失调程度下降,用户室温一致性、热力平衡度更好。调控方式不变的情况下,室外温度大幅下降会破坏二次网的水力平衡状态。A secondary network balancing case located in severe cold region was studied to analyze how the buildings return water temperature affect the room temperature. With massive data analysis, standard deviation、variance and thermal balance level was used to assess room temperature integrity. Hydraulic disorder was eased when the return water temperatures were close to each other. And better consistency of room temperature data was achieved with hydraulic balance. Extreme outdoor temperature change could break hydraulic balance.
