厚重型被覆结构对被动式太阳房室内热环境的影响

Study on the Influence of Thick-and-heavy Envelope to Indoor Thermal Environment of Passive Solar House

由于利用实体模型研究被动式太阳房室内热环境的周期较长、费用较高,为了能够经济、快速地研究被动式太阳房室内热环境,本文采用Fluent软件分别对新疆石河子地区某厚重型被覆结构蓄热的集热蓄热墙式被动太阳房及对比房进行了室内热环境的模拟与分析。结果表明:厚重型被覆结构可以在冬季提高被动式太阳房室内温度5℃以上;提高外墙内壁面温度9℃;室内温度波动可以控制在3℃以内,从而提高了集热蓄热墙式被动太阳房的热舒适性。

A long cycle and higher cost in studing the indoor thermal environment of passive solar house by physical model.In order to shorten the cycle and reduce the costs, the authors simulated and analyzed the indoor thermal environment of passive solar house heat storing of thick-and-heavy envelope and contrast house in the Shihezi in Xinjiang by using the Fluent software. The simulation results indicated that the thick-and-heavy envelope could raise five degrees of the indoor temperature of passive solar house in winter, and raise nine degrees of the internal face of the exterior wall.The indoor temperature fluctuations could be controlled within three degrees which improved the thermal comfort of passive solar house,consequently.
