The thermal comfort conditions of low-temperature radiant floor heating system energy saving research

JIN Junjie,TANG Zhonghua,GAO Lifu,TANG Li(School of Civil Engineering and Architecture,Southwest University of Science and Technology,Mianyang 621010,China)  
Through the comfort temperature range of 16℃ ~ 18℃,14℃ ~ 16℃ intermittent heating experiment of low-temperature floor radiation,the temperature of outdoor air,indoor air temperature of each measuring point,the floor surface temperature,supply and return water temperature and water flow are measured,and they are contrasted with the intermittent heating of work and continuous heating throughout the day.The results showed that,under the condition of thermal comfort of intermittent heating,small temperature gradient changes,the human comfort better than traditional intermittent heating at the same time,energy saving effect is obvious.Future universal heating in winter in the southwest has become a trend,the experiment provides reference and basis for the study of low-temperature floor radiation intermittent heating operation in the winter of southwest region.
