绥化地区地板辐射式采暖居住建筑冬季室内热舒适调查分析

Field study on occupant thermal comfort in radiant floor heating system residential buildings of Suihua city in winter

为了研究严寒地区冬季采暖期居住建筑室内的热环境状况,以绥化地区地板热辐射式采暖住宅为例,调查了其室内热舒适现状,探讨了改善建筑室内热环境的方法,采用测试、问卷调查等方式和以ASHRAE的7级热感觉标度,对该类建筑冬季室内热舒适情况和热感觉主观反映进行统计分析.结果显示,该地区冬季地板热辐射采暖居住建筑室内温度偏高、居民的热期望温度为24.9℃、冬季80%可接受的舒适温度范围为21.9~25.8℃.结合该地区特点,提出适合绥化地区地板辐射式采暖居住建筑冬季室内舒适温度区间为23~25℃,为改善当地住宅建筑节能设计提供依据.

To reveal the indoor thermal environment in winter heating period in severe cold regions, taking the residential buildings with radiant floor heating system in Suihua as the research object, the indoor occupant thermal comfort conditions of residents are explored and ways to improve the indoor thermal environment in Suihua are probed. A subjective questionnaire and a seven-point thermal sensation scale are used to evaluate the thermal sensation, and the data were studied with the statistical method. The results show that the temperature of residential buildings with the radiant floor heating system is higher in Suihua. The preferred temperature is 24.9 ℃ ,and the accepted temperature scope for 80% of the occupants is between 21.9 ℃ and 25.8 ℃. Combined with the characteristics of urban residents living in Suihua, the indoor comfortable temperature of residential buildings with the radiant floor heating system in Suihua ranged between 23 ℃ and 25 ℃ so that the necessary theoretical basis for residential energy saving design is provided to the designers.
