【摘要】 通过模拟计算研究了架空层位于地面之上和地面之下这两种常见的2层结构铝电解厂房的自然通风效果。结果表明,架空层位于地面之下时,地面阻挡对进风口风量有很大影响,当凹槽宽度为1 m时,总风量约减少45%;宽度为3 m时,影响较小,风量约减少9%;宽度为3.5 m时,阻挡的影响可忽略。更多还原

【Abstract】 Studies) by simulation the natural ventilation effect in typical two-storied aluminum electrolytic plants with the operation floor above and under the ground level.As a result,the ground has a significant block effect on the air volume through the bottom inlet.When the distance between the soil wall and outer wall of plant is about 1 metre,the total air volume can be reduced by about 45%,and when the distance is 3 metres,the air volume reduction is much smaller and about 9%,and when the distance is enlarged to 3.5 metres,the influence can be neglected.更多还原
