摘要
为掌握西北农村中小学建筑的供暖用能及室内热环境现状,对青海、甘肃、陕西14所农村中小学建筑进行调查测试,分析学校能源消费结构、供暖用能、各供暖方式的差异(包括使用比例、初投资、运行费用及室内热环境状况)。结果表明:40%以上中小学教室没有采取保温措施,建筑热工性能整体较差,供暖能源消耗量较大。教室空气温度均低于20℃,其中一半以上的教室温度未达到冬季教室内可接受温度的下限值14℃。
To master the current situation of heating energy and indoor thermal environment of the rural primary and secondary schools in the northwest of China, 14 rural primary and secondary schools were investigated and tested in Qinghai, Gansu, Shaanxi. Through analyzing the energy consumption structure, the heating energy, the differences of heating methods （including the proportion of methods, initial investment, operating cost and indoor thermal environment） of schools, the result shows that more than 40% of the primary and secondary school buildings have poor overall thermal performance and high heating energy consumption for having not taken heat preservation measures, and the classroom air temperature is lower than 20℃ where more than half of the room temperature did not reach the lower limit of 14 ℃ temperature.
