摘要
利用CFD软件模拟了所构建的新型绿色单户在外墙不保温、外墙保温层厚度分别为50mm和80mm情况下的室内温度场。结果表明:新型绿色单户建筑不带外墙保温,室内热源表面温度为303K时,室内最大温差为8K,室内温度主要分布在282~284K,室内热源表面温度为308K时,室内最大温差为10K,室内温度主要分布在285~287K;新型绿色单户建筑带外墙保温且保温层厚度为50mm,室内热源表面温度为303K时,室内最大温差为6K,室内温度主要分布在290~291K,室内热源表面温度为308K时,室内最大温差为5K,室内温度主要分布在292~293K;新型绿色单户建筑带外墙保温且保温层厚度为80mm,室内热源表面温度为303K时,室内最大温差为5K,室内温度主要分布在292~294K,室内热源表面温度为308K时,室内最大温差为7K,室内温度主要分布在294~295K。
This article simulates the indoor temperature field of newly-developed household green building by CFD software under the condition of building without external wall thermal insulation and the thickness of external wall thermal insulation is 50 mm and 80 mm.The results show that in the newly-developed household green building without external wall thermal insulation,when the surface temperature of indoor heat source is 303 K,the maximum indoor temperature difference is 8K,the indoor temperature field is mainly distributed in the range from 282 Kto 284K;when the surface temperature of indoor heat source is 308 K,the maximum indoor temperature difference is 10 K,the indoor temperature field is mainly distributed in the range from 285 Kto 287K;in the newly-developed household green building with external wall thermal insulation,when the thickness of external wall thermal insulation is 50 mm and the surface temperature of indoor heat source is 303 K,the maximum indoor temperature difference is 6K,the indoor temperature field is mainly distributed in the range from 290 Kto 291K;when the surface temperature of indoor heat source is308 K,the maximum indoor temperature difference is 5K,the indoor temperature field is mainly distributed in the range from 292 Kto 293K;when the thickness of external wall thermal insulation is 80 mm and the surface temperature of indoor heat source is 308 K,the maximum indoor temperature difference is 5K,the indoor temperature field is mainly distributed in the range from 292 Kto 294K;when the surface temperature of indoor heat source is 308 K,the maximum indoor temperature difference is 7K,the indoor temperature field is mainly distributed in the range from 294 Kto 295K.
