摘要
集热蓄热墙式建筑的研究方向主要是百叶型集热蓄热墙和多孔型集热蓄热墙等。使用Fluent软件,采用RNGk–ε方程湍流模型和太阳辐射模型模拟不同类型被动太阳能集热蓄热墙与室内的传热情况,建立了两种集热蓄热墙和传统集热蓄热墙的模型,模拟了在沈阳冬季和夏季条件下,两种不同集热蓄热墙与传统式集热蓄热墙的墙体内、外壁面温度和室内温度等参数。通过分析比较3种模型的模拟结果得出,百叶型被动太阳能集热蓄热墙在冬季集热性能比其他类型墙体好,室内温度较对比模型提高了3℃,在夏季,有效降低了墙体向室内的热负荷。本研究对集热蓄热墙的建筑改造及进一步的研究有一定的参考价值。
The research hotspots of thermal storage wall style buildings mainly focus on types such as louvered thermal storage walls and porous thermal storage walls.Using Fluent software and RNGk–εthe equation model and solar radiation model simulate the heat transfer between different types of passive solar thermal storage walls and indoor environments.The article established models for two types of thermal storage walls and traditional thermal storage walls,and simulated the internal and external wall temperatures and indoor temperatures of two different types of thermal storage walls and traditional thermal storage walls under winter and summer conditions in Shenyang.By analyzing and comparing the simulation results of three models,it can be concluded that the louvered passive solar thermal storage wall has better heat collection performance in winter compared to other types of walls,with an indoor temperature increase of 3℃compared to the comparative model.In summer,it effectively reduces the heat load of the wall towards the interior.This research has certain reference value for the architectural renovation and further research of the thermal storage wall.
