1. Fair Define filter efficiency at all levels
In this case,
The main points in determining the efficiency of the filter are that the performance of the final filter should be reliable and that the efficiency of the pre-filter is fair and that the maintenance of the low-level filter and the pre-filter be facilitated.
In this case,
2. Increase the filter area
In this case,
Filter filter area, can accommodate more dust, its life is long. And filter area, the air flow through the material on the low speed, the resistance of the filter is small.
In this case,
3. Adjust the filter efficiency at all levels
In this case,
Pre-filter filtration efficiency is low The pre-filter can be adjusted by the filtration efficiency, the dust block in the pre-filter.
In this case,
4. should not exaggerate the additional effect of the filter
In this case,
5. Weather factors affect the filtration effect
In this case,
If the use of filter willow more, in the air-conditioning design should take appropriate measures, such as changing the height of the inlet or in the air inlet to protect the network. If the measures are not properly, then only a trick: the season in the Piaoxu frequently change filters.
In this case,
6. Cleaning technology is difficult to promote
In this case,
High efficiency filters, the use of occasions are very particular about the filter even if the wash is not bad, it is best not to wash, unless there is a thorough grasp of clean, clean performance does not change.
