传统采暖房内热环境的三维数值模拟

Three-dimensional numerical simulation of thermal environment in traditional radiator-heated houses

为了分析传统散热器采暖房内的热利用效果,在抽象物理模型基础上,建立散热器采暖房内热环境的三维数值模型,模拟传统采暖房内的热环境,基于新型采暖热舒适性标准分析散热器安装位置对采暖房内热环境的影响.结果表明,按照国家采暖规定,在6 m×5 m×3.2 m的房间内,安装在内墙上的散热器不仅能更好地满足居民热舒适度的需求,而且比安装在外墙上的散热器节能7.63 W/m2.

In order to analyze the heat utilization in traditional radiator-heated houses, three-dimensional numeric model of thermal environment was established for an abstracted physical model and the influence of position of radiators to thermal environment was analyzed by new thermal-comfort-standards for heating systems. The results show that the radiators on the inner walls of a 6 m× 5 m× 3. 2 m house would not on- ly better meet the requirement of thermal comfort but also save energy of 7. 63 W/m^2 than those on the outer walls.
