农宅冬季室内热湿环境及空气品质实测分析

Measurement and Analysis of Indoor Thermal and Humid Environment and Air Quality in Rural Buildings in Winter

结合天津地区农村建筑的特点及农村建筑特殊的采暖方式,选取5户典型农宅进行现场测试。基于测试数据,利用PMV数值分析方法及灰色系统理论方法把测试的结果进行计算与分析。结果表明:农宅室内温度随着室外温度的变化而发生变化,其变化趋向相同;PMV数值计算结果表明,实验阶段1号农宅即采用土暖气,燃烧材质为大同煤的供暖方式的室内热舒适度概率最大为58.6%;利用灰色综合评价的方法并进行相关计算后表明:实验阶段3号农宅即独立的水电暖气片供暖方式的室内空气品质均为未污染,空气品质优良。通过对天津地区农村建筑采暖方式的测试分析,对今后农村采暖方式的选取有一定的指导意义。

Based on the characteristics of rural buildings in Tianjin and the special heating methods of rural buildings,five typical farm houses are selected for field test. Based on the test data,both the PMV numerical analysis method and the grey system theory are utilized to analyze the test results. The results show that the farmer ＇s indoor temperature is positively correlated with the outdoor temperature. PMV numerical calculation results show that the indoor thermal comfort probability is up to 58. 6%during the experimental stage in the No. 1 farm house with Datong coal for heating. The results of grey comprehensive evaluation shows that the indoor air quality is not polluted during the experimental stage in the No. 3 farm house with independent hydropower radiator heating. Through the test and analysis of the heating methods of rural buildings in Tianjin,this paper has certain guiding significance for the selection of heating methods in rural areas in the future.
