内置翅片型Trombe墙对寒冷地区供暖房间内热环境的影响
Effect of a built-in finned Trombe wall on the thermal environment of heating rooms in cold regions
摘要
Abstract
To evaluate the contribution of a built-in fin-type Trombe wall to reducing indoor heating energy consumption,this study takes a typical residential building in Lanzhou as the research object.Fins are installed on the heat-absorbing surface of the Trombe wall to enhance heat transfer and thereby improve the indoor thermal environment.The results show that the isosceles right-triangle fins with a height of 20 mm,a transverse spacing of 0.20 m,a longitudinal spacing of 0.533 m,and an in-line configuration provide the greatest improvement in heat transfer performance and indoor thermal conditions. Over the entire simulation period, the average Nusselt number (Nu) of the fin-type Trombe wall is 21.28 higher than that of the finless wall. Compared with aconventional room, the energy-saving rates of the finless Trombe wall and fin-type Trombe wall rooms are 36.38％ and 44.63％ respectively, meaning the fin-type Trombe wall yields an additional 8.25％ energy-saving improvement.关键词
