摘要
采用数值模拟方法研究常规商用1175 mm×1175 mm(4×4模数)风机过滤单元(fan filter unit,FFU)的马达底板形状、静压箱厚度等结构特性与面出风均匀性的关系,并探究了不同测点分布对测试结果的影响。结果表明:对于4×4模数的FFU,可通过减小马达底板面积和增大静压箱厚度来提高出风均匀性,但存在临界静压箱厚度;在进行出风均匀性测试时,测点分布对测试结果有较大影响,其中6×6中心分布的方法最为适宜。
The relationship between the structural characteristics(i.e.,motor baseplate shape and plenum chamber thickness)of the common commercial 1175 mm×1175 mm(4×4 module)fan filter unit(FFU)and the air velocity uniformity was studied using numerical simulation methods.The influence of test point distribution on the test results was explored.The results show that for the 4×4 module FFU,a higher uniformity can be achieved by reducing the area of motor baseplate and increasing the thickness of plenum chamber,but there is a critical thickness of plenum chamber.When testing the air velocity uniformity,the distribution of test point has a great influence on the results,and the method of 6×6 central distribution is the most suitable.
