摘　　要：以上海某住宅建筑作为实验场地,选取位于同一栋楼的4楼、户型相同的2套三室两厅户型为研究对象,2个用户分别安装冷凝式燃气供暖热水炉(简称冷凝炉)与非冷凝式燃气供暖热水炉(简称常规炉)进行实验,对比分析冷凝炉与常规炉用户平均室内温度、供回水温度、热输出、燃气消耗量及热效率。通过实验得出:冷凝炉用户室内温度波动小,舒适性较高,冷凝炉对室内温度的控制优于常规炉。冷凝炉热输出略小于常规炉。冷凝炉热效率高于常规炉。Taking a residential building in Shanghai as the experimental site,two sets of three bedroom and two living room apartments located on the fourth floor of the same building with the same apartment type are selected as the research objects.The two users are respectively installed with condensing gas heating and hot water combi-boiler(referred to as condensing combi-boiler)and non-condensing gas heating and hot water combi-boiler(referred to as conventional combi-boiler)for the experiment.The average indoor temperature,water supply and return temperature,heat output,gas consumption and thermal efficiency of condensing combi-boiler and conventional combi-boiler are compared and analyzed.Through experiments,it is concluded that the indoor temperature fluctuation of condensing combi-boiler users is smaller,and the comfort is higher.The condensing combi-boiler has better control over indoor temperature than conventional combi-boiler.The heat output of the condensing combi-boiler is slightly smaller than that of the conventional combi-boiler.The thermal efficiency of condensing combi-boiler is higher than that of conventional combi-boiler.
