成都地区居住建筑不同供暖末端能耗与满意率调研

摘要

Floor heating with gas boiler (FH),radiator with gas boiler and air-source heat pump (ASHP) are the most popular heating terminals in residential buildings of hot summer and cold winter zone.Investigates 10 families in Chengdu area (4 with FH,2 with radiator and 4 with ASHP) through indoor thermal environment monitoring,questionnaire surveys and heating energy consumption analyses.The results show that the indoor air temperature varies from 5 ℃ to 22 C.Different heating terminals result in significantly difference of heating energy consumption,however the overall thermal comfort satisfactory level is stable at a relatively high standard.For example,the FH families consume more than 5.87 kg/m2 coal per month,8 times as much as that of the ASHP families.In addition,the energy consumption varies a lot in different households with FH.It is not found that the increase of heating energy consumption leads to the improvement of thermal comfort satisfaction.%夏热冬冷地区居民供暖末端形式主要有燃气壁挂炉+地板供暖系统、燃气壁挂炉+散热器系统和热泵系统等.对位于夏热冬冷地区的成都地区10户住宅(4户燃气壁挂炉+地板供暖系统,2户燃气壁挂炉+散热器系统和4户热泵系统)的冬季室内热环境进行了现场测试、主观问卷调研及供暖能耗分析研究.实测结果表明:成都地区冬季住宅室内温度在5～22℃范围内;不同供暖末端对应的冬季室内温度有高有低,但住户都有较高的热环境满意率(不满意率在5％以下);能耗水平存在较大差别.其中,燃气壁挂炉+散热器用户每月标准煤耗量达5.87 kg/m2,等效能耗水平是热泵用户的8倍以上.不同家庭即使同样采用燃气壁挂炉+地板供暖系统,能耗也会有较大差别.本次研究未发现能耗水平与满意率存在显著相关性.
