摘要
Abstract
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 apart-ment 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 con-densing 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 con-densing 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 com-fort is higher.The condensing combi-boiler has better control over indoor temperature than conventional com-bi-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.关键词
