间歇式用能模式下墙体热分析

针对夏热冬冷地区间歇式用能特点,采用ANSYS软件对外墙内外保温墙体进行热分析。通过间断式施加温度荷载模拟空调运行,分析两种保温形式的墙体内温度变化情况。研究结果表明,受墙体内侧温度荷载的影响,内保温墙体内表面温度变化明显,且热量集中分布在内侧保温层部分,不易散失;外保温墙体受内侧温度荷载的影响较小,热量在墙体内分布均匀。在相同时间内,内保温需要施加荷载的时间明显比外保温的少。

The Study on Wall thermal energy under intermittent pattern

According to the characteristics of intermittent energy consumption in Hot Summer and Cold Winter region ,we analyzed the exterior wall of internal insulation and external insulation by using ANSYS software in the thermodynamic module .By applying intermittent temperature load to simulate air conditioning running , we studied the wall’ s temperature changing in two kinds of thermal insulation .T he results show that affected by the inside temperature load of the w all ,the inner surface of interior insulation temperature changes significantly ,and the heat is concentrated on the medial portion of the insulation layer and it’s not easy to be lost ;exterior insulation is less affected by the inside temperature load ,heat evenly distributed in the wall .At the same time ,the internal heat preservation needs to apply the load time is significantly less than the external insulation .
