How to calculate the wind volume of high efficiency filter?
The wind volume of the high-efficiency filter can be calculated as this, and the wind volume of the high-efficiency air filter is generally determined based on the wind speed and size of the high-efficiency filter; The rated wind speed of a generally efficient air filter is between 0.3 and 0.6 M/S, and the median value can be 0.45; For example, we all know that the size of the 1000 wind flow efficient filter is: 484 * 484 * 220 converted out
Introduction of Air Volume Calculation Method for Specially Efficient Filters
Premise: The wind volume of the high efficiency filter is generally determined by the wind speed and size of the high efficiency filter;
The fixed wind speed of a generally efficient filter is between 0.3 and 0.6 M/S, and the median value can be 0.45;
For example, we all know that the size of the 1000 wind efficiency filter is: 484 * 484 * 220 conversion out.
This method is simple, but it is not accurate enough. There are more accurate calculation methods below.
High efficiency filters. That's what wind is.
Introduction to the air volume calculation method of professional high-efficiency filters:
Calculated by the international standard 484 * 484 * 220 high efficiency filter:
The rated wind is 1000M3/H with initial resistance at 200PA.
1. 28 % discount / 10 CM for filter paper,
2. Effective area calculation of filter paper: 0.475 * 0.475 * 280 * 0.2 * 2 = 25.27 square meters, of which: 0.475 is the effective length of filter paper
3.0.475 is the effective width of the filter paper, 280 is a 1M filter paper folded double layer, and 0.2 is the actual height of the filter paper
4. Filter section wind speed, 1000/3600/25 .27 = 0.011 m/s, that is, when the cross-section wind speed of the filter paper is 0.011 m/s, the initial resistance of the filter paper is 200PA,
Conclusion: High efficiency filter wind, a filter of 900 * 600 * 370 0.88 * 0.58 * 280 * 0.35 * 2 * 0.011 * 3600 = 3961 m3/h
Among them: 0.88 is the effective length of filter paper
0.58 valid width of filter paper
Number of folding sheets for standard filter of 280 M
0.35 is the actual height of the filter paper
2 is double layer
0.011 wind speed of filter paper section
3600 is an hour equal to 3600 seconds. This is a standard method for calculating high efficiency filters with partitions!
