Study On The Indoor Thermal Environment About The Low Temperature Hot Water Radiant System Heating In Chengdu Region

As the antiquity and new heating type,the low temperature hot water radiant system heating widely catch people's attention.The domestic and overseas experts make comprehensive study.Now,some in our nation already start to use widely the system because of heating,especially the North. People's living custom,dress and climate in Chengdu region differ from the North.Along with development of social economy and standard of living for the better,people demand the indoor thermal environment up and up and begin to pay attention to the quality on the indoor thermal environment and focus on the comfort and healthiness be closely linked with oneself,from"the dweller lack his house"to"the dweller hold his house"to"the dweller improve his house". Study on using the low temperature hot water radiant system heating are few in Chengdu region.The text discuss mainly some questions thereinafter:(1)Synthetical discuss the actual study about the low temperature hot water radiant system heating and research for using the system now in Chengdu region.(2)By PMV-PPD evaluation index as academic gist,simulate calculates indoor thermal environment in Chengdu region after running the low temperature hot water radiant system heating in winter,for studing the thermal comfort standard adapt to the Chengdu people.(3)Make experiment about the low temperature hot water radiant system heating in the region,to validat the forenamed content and make comparalist.(4)Combining with economy,analyse and compare the impact on indoor thermal environment in the region after running the low temperature hot water radiant system heating and others heating type.The results show that the system that is the healthy,comfortable, saving heating type can meet the demand about thermal comfort in Chengdu region. The system's indoor temperature should be 18 to24℃ for thermal comfort in the region,up 16 to 20 ℃ stipulated as the design...
