火墙是北方寒地常用的传统采暖设施。通过对严寒地区村镇住宅火墙的现状调查与实地测试,从火墙的采暖效果和散热性能两方面分析其在冬季对室内热环境的影响。结果表明火墙房间的热环境基本满足舒适性要求。但也发现火墙供暖房间室温波动较大、室温及壁面温度分布不均等现象,并针对此缺陷提出了相应的改进措施和设计方法,使改进后的火墙更能满足舒适和节能要求。
Fire wall is commonly used in the northern cold traditional heating facilities. Based on the survey of the residential fire walls in the cold area and the field test, the influence of the fire wall on the indoor thermal environment in winter is analyzed from the heating effect and the heat dissipation performance of the fire wall. The results show that the thermal environment of the fire wall room basically meets the comfort requirements. However, it is also found that the room wall temperature fluctuates greatly, the room temperature and the wall temperature distribution are not equal, and the corresponding improvement measures and design methods are put forward to make the improved fire wall better meet the requirements of comfort and energy saving.
