五类家用空调过滤网性能比较
|
摘要
家用空调过滤网是空调的重要组件,通过研究五类过滤网(尼龙初效过滤网;厚款为3mm薄款为1mm的静电滤棉HEPA初效滤网;折高为12mm的HEPA过滤纸;尼龙初效过滤网与薄款静电滤棉的叠加网)在不同风速(2.4m/s、2.7m/s和3.3m/s)、不同粉尘条件下(不加模拟粉尘和加1g粒径为16.9μm的粉尘)网的前后压差,并测定尼龙初效过滤网、薄款静电滤棉和叠加网对2g模拟粉尘的过滤效率,分析五类过滤网的差异,确定风阻较小且除尘率较高的过滤网。实验结果表明叠加网综合性能最好,过滤效率为69.23%,可为家用空调器过滤网的优化提供参考。
Household air conditioning filter network is an important component of air conditioning, through the study of five kinds of filter net(nylon initial filter net; 3 mm and 1 mm HEPA electrostatic initial filter net; HEPA filter paper with 12 mm high;nylon initial filter net with thin HEPA electrostatic initial filter net) at different wind speeds(2.4 m/s, 2.7 m/s and 3.3 m/s), different dust conditions(without simulated dust and 1 g particle size of 16.9 microns), the pressure difference of the net, and the filtration efficiency of the nylon filter net, the thin electrostatic filter and the superposition net to the 2 g simulated dust are measured, and the difference of the five kinds of filter nets is analyzed. The best filter with small wind resistance and high dust removal rate is determined. The results show that the Superimposed network has the highest cost performance and the filtering efficiency is69.23%, it can provide reference for the optimization of household air conditioner filter screen.
