甘肃庄浪县农户吊炕的热效率模拟分析

中国西部黄土丘陵地区冬季比较寒冷,取暖用能成为必然需求,炕是农村家庭的主要取暖设施。在甘肃庄浪县2个村的6户农家建造新式节能吊炕,并与传统炕一起进行室内外的温度观测和燃料使用记录,获取连续的时间序列数据,建立数学模型。用matlab7.0程序,模拟分析冬季取暖期农户日常生活情景下2种炕的热效率。结果表明,每农户年平均取暖用能占到家庭生活用能的一半。高崖韩村吊炕户和传统户取暖用能折合标准煤分别为868.43和1 338.51 kgce,下湾村分别为956.36和1 583.50 kgce。吊炕的热效率在27%~37%之间,比传统炕高出一倍以上。使用吊炕能够有效提高燃料的利用效率,是现阶段解决农户...

Summary:中国西部黄土丘陵地区冬季比较寒冷,取暖用能成为必然需求,炕是农村家庭的主要取暖设施。在甘肃庄浪县2个村的6户农家建造新式节能吊炕,并与传统炕一起进行室内外的温度观测和燃料使用记录,获取连续的时间序列数据,建立数学模型。用matlab7.0程序,模拟分析冬季取暖期农户日常生活情景下2种炕的热效率。结果表明,每农户年平均取暖用能占到家庭生活用能的一半。高崖韩村吊炕户和传统户取暖用能折合标准煤分别为868.43和1 338.51 kgce,下湾村分别为956.36和1 583.50 kgce。吊炕的热效率在27%~37%之间,比传统炕高出一倍以上。使用吊炕能够有效提高燃料的利用效率,是现阶段解决农户取暖问题的较好途径。因此建议,国家应像推广沼气一样推广吊炕的应用,改善农户冬季室内的热舒适性。

As the weather is cold in the winter in the loess hilly region of western China, space heating becomes a necessary demand for rural households. Kang is the main method of heating in rural households of this region. A new type of kang (suspended kang) was constructed in six rural houses and traditional kang (a heatable brick bed) constructed in four rural houses in two villages in Zhuanglang County. The suspended kang was raised above the floor on columns, which is different from traditional kang on the ground. Indoor and outdoor temperatures were
