Abstract
To address the issue of gas load characteris-tics in household heating in wet and cold climate re-gions,447 users of gas-fired heating and hot water combi-boilers in Chongqing were selected as the re-search subjects.Through questionnaire surveys,com-bined with multi-source data from gas meter reading video monitoring systems and gas-fired heating and hot water combi-boiler operation time monitoring systems,mathematical statistics and correlation analysis meth-ods were used to conduct an in-depth analysis of the temporal and spatial distribution patterns of gas con-sumption and its influencing factors.January is identi-fied as the month with the highest monthly gas con-sumption,with December 30 being the peak consump-tion day.On the peak day,the highest hourly gas con-sumption occurrs between 20:00 and 21:00,with an hourly peak coefficient of 1.32.The average daily gas consumption of users using all-day heating,intermit-tent heating,and non-enabled heating was 14.79 m3,10.63 m3,and 0.95 m3 respectively.Among these,us-ers using all-day heating exhibit the smallest hourly gas consumption fluctuation,whereas those using non-enabled heating show the largest fluctuation.There is a significant negative correlation between the average daily gas consumption of heating users and the daily average temperature.Specifically,for every 1 ℃ de-crease in the daily average temperature,the average daily gas consumption of heating users increases by ap-proximately 1.094 m3.Additionally,the monthly gas consumption of heating users is positively correlated with the heating area;the larger the heating area,the higher the monthly gas consumption.Furthermore,the monthly gas consumption of users using underfloor heating at the end of the heating system is greater than that of users using radiators.On average,the monthly gas consumption of users using underfloor heating is about 1.1 times that of users using radiators.关键词
