不同供暖时间比对间歇供暖房间内围护结构能耗的影响

Effect of the Ratio of Heating Time on Interior Building Envelope in Intermittent Heating Room

为了探究夏热冬冷地区冬季内围护结构在不同供暖时间比下的能耗特征,本文通过数值模拟的方法,对外墙内、外保温方式下的间歇供暖房间内围护结构的传热过程及能耗特点进行分析。结果表明,供暖时间比λ越大,房间的平均热指标越小;不同供暖时间比时,内围护结构的能耗比都很大为75%左右;当供暖时间比减小时,内墙的无效能耗源比增加,最大为70%左右。

In order to explore the energy consumption features of interior building envelope under different heating time ratios in hot summer and cold winter. Adopting numerical simulation,this paper set to analyze the heat transfer process and energy consuming features of the interior envelope structure within intermittent heating room under inner and outer wall insulation,respectively. The results indicate that the larger ratio of heating time,the lower heating index of room. And no matter what the ratio of heating time is,the energy consumption ratio of interior envelope are mostly 75%. But with the ratio of heating time decreasing,the ratio of ineffective energy consuming sources rises up to increases 70% or so.
