计量供热系统变流量影响因素分析
Analysis of influencing factors of variable flow rate in a heat metering system
摘要：
基于对某分户计量供热小区变流量测试结果和住户调阀模式调查结果，分析了计量供热系统流量变化的主要影响因素。研究发现，开窗是恒温阀自动调节个体流量波动的最主要因素；住户频繁调节及长周期调节分别带来个体流量的短期阶跃变化和长周期变化；耦合作用使住户个体流量受其他住户调节行为影响，并削弱个体调节对整体流量变化的影响；同时发生率关系到个体流量变化对整体流量变化的综合影响。对该小区进行了流量变化概算，结果与测试结果较一致。
Abstract：
Based on the test of variable flow rate and investigation of consumer’s behavior regulation in a household heat metering quarter, analyses the main factors influencing flow rate and concludes that window opening is the most important factor for the individuals with thermostatic radiator valve’s self-control, that consumers frequent and long-term adjustment results in short-term step change and long period change of flow rate separately, that due to coupling interaction the individual flow rate is influenced by others’ regulation and the effect of individual regulation on holistic flow rate change is weakened, and that concurrence rate is involved in the integrated impact from individual change to the whole. Estimates the flow rate change of the quarter and the result well agrees with the measured values.
