双向空气净化换气装置结构设计
|
摘要
针对现代建筑室内空气污染、室内空气净化器功耗成本较高且不能与外界交换气体等问题,基于Pro/E三维结构建模技术,开发一款新型双向空气净化换气装置。经有限元模态分析,认为可对其材料优选,并采用Fluent软件进行空气流体计算与仿真,对比优选前后的流体参数。结果表明,弹性模量对装置一阶频率影响显著,将外形部分的碳纤维复合材料换成铝合金材料,一阶频率由63.3 Hz降为37.1 Hz,满足不共振条件,各项流体参数较优选前均有小幅度下降,换气次数由4.66次/h降为4.38次/h,依然符合国家标准。
In view of the problems of indoor air pollution in modern buildings, high power consumption of indoor air purifier and no outdoor air exchange, a new two-way air purifying and ventilating device was designed and developed based on Pro/E three-dimensional structure modeling technology.Through the finite element modal analysis, it is considered that the material can be optimized, and the air-fluid calculation and simulation can be carried out by using Fluent software to compare the fluid parameters before and after the optimization.The results show that the elastic modulus has a significant influence on the first-order frequency of the device,and that the first-order frequency is reduced from 63.3 Hz to 37.1 Hz after the carbon fiber composite material is replaced by aluminum alloy material in the external part of the device which meets the non-resonance condition.The fluid parameters decrease slightly compared with those before optimization,and the number of ventilation per hour decrease from 4.66 times/h to 4.38 times/h, which still accords with the national standards.
