摘　　要：目的研究传统采暖方式下农村住宅的室内的温度和气流组织分布，评价室内热舒适性．方法以农村住宅采暖房间为研究对象，通过对农村住宅的采暖房间实地测试，建立该采暖房间的数学和物理模型，室内空气自然对流，采用k-e模型进行描述，使用Airpak软件对在传统采暖方式下农村住宅的室内热环境进行数值模拟分析．结果通过25—30d的实测，得到室内全天平均温度是8．5℃，以20：30时刻为例，炕面上方测点温度高于地面上方测点2℃左右，以这个时刻的条件作为模拟对象，计算出室内地面活动区平均温度10℃，炕面上方平均温度稍高于12℃，与实测值基本相符．结论农村住宅依靠火炕或火墙供暖不能满足居民对舒适性的要求．对于新农村的意义是要提高其室内的热环境，既需要做好围护结构的保温措施，又需要采用舒适的采暖方式．The paper aims to evaluate the indoor thermal comfort of the rural residence under the traditional heating mode. By taking the heating room of rural house as the research object, the temperature is tested in rural house, and then the modeling of heating room is established by the Airpak software. Natural convection of indoor air is described by using k-emodel. Indoor thermal environment is simulated and analyzed by the Airpak software about the rural house of the traditional heating way. From December 25 to 30, according to the test data, the average temperature of indoor is 8.5℃ all day. At 20：30, for example, The kang surface measuring point temperature is 2℃ higher than the floor point. Taking the condition at this moment as the simulation object, the average temperature of the activity area of the ground is10℃by software calculation, and the average temperature of kang surface is a little higher than 12℃. This is basically consistent with the measured value. Rural residence which relies on kang and fire wall heating cannot meet the requirements of residents for comfort. Suitable heat preservation measures and a comfortable heating means are needed to im- orove the indoor thermal environment.
