The area of the hepa filter layout section
2 when decorate flanking plenum, should one or contralateral decorate, the side of the filter with than should not be less than 0. 75, the static pressure of the air in the cabinet shall be fully mixed.
3 when is limited by the height and not allowed to indoors repair, can be used with resistance function of leakage air supply side and the filter
Device layout in the plenum, but should be as close to static pressure box, static pressure of the air in the cabinet shall be fully mixed measures; jie
Net with breath should be under less than 0. 85.

4. Less than 100 grade clean area, when the centralized arrangement of air supply, air supply level at the end of the hepa filter can be concentrated in the mouth
Decorate, also can be scattered layout, but must be set on the surface of the supply air flow layer.
5. Clean all clean room in the department of surgery, should adopt bilateral lower return air; When bilateral distance not more than 3 m, can be in it
In the lower side return, but should not adopt four or four side return. Clean and clean corridor can be used on the return air corridor.
6. Above the lower inlet hole above height should not exceed the ground 0. 5 m, the hole bottom should not be less than off the ground
0. 1 m. Ⅰ the appropriate level of the clean operating room return air mouth continuous arrangement. Indoor inlet air flow rate should not be greater than 1. 6 m/s, go
Gallery inlet air flow rate should not be greater than 3 m/s.
7. Clean operating room shall be used indoor air return, no residual pressure valve to return air corridor.
8 clean operating room must set the upper outlet, its location should be at the top of the client‘s head side. Vents blend wind speed should be
No larger than 2 m/s.
9 Ⅰ, Ⅱ clean operating room should not be adding another air purification unit.
