覆土建筑冬季室内热舒适性研究

Thermal Comfort of the Earth-Sheltered Architecture in Winter

通过对西安地区某覆土建筑冬季室内热环境的测试,分析了测试房与对比房的温度测试数据。结果表明测试房内各测点逐时温度均高于对比房,室内温度变化幅度也明显小于对比房,且覆土建筑的室内温度略高于当地室内设计采暖温度。在测试的基础上采用主观温度法对室内热舒适性进行参考性评价,结果显示测试房室内热环境较好地满足了使用者对热舒适的需求。因此,覆土建筑在冬季能够有效维持室内温度,提高热舒适性,同时能够降低建筑采暖能耗。

The testing room and comparing room are analyzed through testing the winter indoor thermal environment of an earth-shehered building in Xi＇an. The results show that the temperature of each measuring point of the testing room is higher than that of the comparing room, the indoor temperature change amplitude is much smaller, the indoor temperature of earth sheltered building is slightly higher than the local indoor heating design temperature. Based on the test data, the indoor thermal comfort is evaluated by the method of subjective temperature, the results show that the indoor thermal environment of testing room meets the thermal comfort requirements of users well. Therefore, earth-sheltered building can effectively maintain room temperature in winter, improve thermal comfort, and reduce the building heating energy.
