Analysis of influencing factors of variable flow rate in a heat metering system

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.
