摘要/Abstract

摘要： 落地炕和架空炕是目前北方农村冬季普遍采用的两种采暖设施,它们的构造与密封性对采暖室内的热湿环境与空气质量有显著影响.参照相关国家标准,在甘肃省临洮县对使用落地炕与架空炕采暖的室内热环境和空气质量进行了连续的对比试验研究.结果表明:架空炕采暖室内日平均温度为12.6 ℃,比落地炕采暖室内日平均温度10.8 ℃高出1.8 ℃;使用PMV-PPD指标评价发现,架空炕室内热舒适度综合评价等级为Ⅱ级,落地炕室内综合评价等级为Ⅲ级.架空炕采暖室内空气质量PM_2.5、PM₁₀和CO指标优于落地炕采暖室内指标,两铺炕采暖室内首要污染物均为PM₁₀.架空炕采暖室内空气质量等级为轻污染,落地炕采暖室内空气质量等级为重污染.

关键词: 落地炕, 架空炕, 室内热环境, 室内空气质量, 室内舒适度

Abstract: Suspended kang and landed kang are two types of heating device used popularly in northern China in winter currently. Their structure and sealing performance have an obvious influence on the indoor thermal environment and indoor air quality. Referring to relevant National Standards, a continuous comparative experimental investigation of indoor thermal environment and air quality of heating with those two kinds of kangs was conducted in county Lintao, Gansu. The result showed that the indoor daily mean temperature of heating with suspended kang would be 12.6 ℃, being 1.8 ℃ higher than that of heating with landed kang (10.8 ℃). It was found by employing PMV-PPD index evaluation that the comprehensive evaluation grade of indoor thermal comfortableness would be class-Ⅱ for the suspended kang, and that of landed kang would be class-Ⅲ. Indoor air quality PM_2.5, PM₁₀ and CO index of heating with suspended kang would be superior to that of landed kang, the indoor primary pollutant of heating with both types of kang would be PM₁₀. The indoor air quality grade of heating with suspended kang would be pollution, the indoor air quality grade of heating with landed kang would be heavy pollution.

Key words: landed kang, suspended kang, indoor thermal environment, indoor air quality, indoor comfortableness
