                摘要:

                以藏区某典型居住建筑模型为基础,利用能耗模拟软件EnergyPlus,对设置移动保温装置建筑的供暖季热负荷、通过外窗的传热、自然室温的变化进行了模拟。结果显示:在北向和南向设置移动保温装置后供暖季建筑室内热负荷分别降低了7.8%16.6%;通过外窗的失热量明显减少;建筑室内热环境明显改善,并有助于改善建筑室内温度的稳定性;移动保温装置对建筑室内热环境的影响随移动保温装置外保温苯板厚度的增大而减小,当保温苯板厚度为0.027 m时,建筑自然室温日最低值的平均值为14 ℃。

                Abstract:

                Based on a Tibetan typical residential building model, simulates the heat load, exterior window heat transfer and natural room temperature change of the building with mobile thermal insulation device in the heating season using EnergyPlus. The results show that the heat loads of the building with mobile thermal insulation in the north and south orientations decrease by 7.8% and 16.6%, respectively. The heat loss from exterior window reduces significantly. The building indoor thermal environment is significantly improved, which benefits to the stability of the indoor room temperature. With the thickness of the benzene board increasing, the influence of mobile thermal insulation device on the indoor thermal environment decreases. When the thickness of benzene board is 0.027 m, the average daily lowest natural room temperature is 14 .
