摘要
为研究穿斗式木结构民居夏季室内热环境,设计制作了1个全尺寸民居试验模型,测量了模型的室内外空气温度、湿度、室外风速、墙壁及顶棚的壁面温度等,并采用红外热成像仪记录了壁面温度变化过程。基于试验数据,分析了模型的温度变化规律,揭示了穿斗式民居模型的传热机理,给出了室内温度预测模型及热舒适性评价。研究结果表明:白天室内外温差较小,但阁楼温度明显高于房间温度;热量主要通过墙壁及顶棚传递至室内,房间之间的热量传递较少;室内温度预测模型具有较高的计算精度,民居白天室内热,舒适性较差。
To study the indoor thermal environment of Chuandou-style timber buildings in summer,a full-size test model was designed and produced.The indoor and outdoor air temperature,humidity,outdoor wind speed,and wall temperatures of the model were measured,and the wall temperature changes were recorded using an infrared thermal imager.Based on test data,the temperature variation pattern of the model was analyzed,and the heat transfer mechanism was revealed.An indoor temperature prediction model and thermal comfort evaluation were provided.The research results indicated that the temperature difference between indoors and outdoors during the day was relatively small,but the temperature in the attic was significantly higher than that in the room.Heat was mainly transmitted to the interior through walls and ceilings,with less heat transfer between rooms.The indoor temperature prediction model had high calculation accuracy,and the indoor thermal comfort of residential houses during the day was poor.
