How can I know the air volume I need?
| Room type | Non-smoking | Slight smoking | Heavy Smoking | |||||
| Ordinary ward | Gym | Theater&mall | Office | Computer room | Dining room | VIP room | Meeting room | |
| Personal frsh air consumption(m³/h)(Q) | 17-42 | 8-20 | 8.5-21 | 25-62 | 40-100 | 20-50 | 30-75 | 50-125 |
| Air changes per hour(P) | 1.06-2.65 | 0.50-1.25 | 1.06-2.66 | 1.65-3.9 | 2.5-6.25 | 1.25-3.13 | 1.88-4.69 | 3.13-7.81 |
Example
The area of a computer room is 60 sq meter(S=60), the net height is 3 meters(H=3), and there are 10 persons(N=10) in it.
If it is calculated according to “Personal fresh air consumption”, and assume that:Q=70, the result is Q1=N*Q=10*70=700m³/h
If it is calculated according to “Air change per hour”, and assume that: P=5, the result is Q2=P*S*H=5*60*3=900m³/h
Since Q2＞Q1，Q2 is better for selecting the unit.
As to special industry such as hospitals(surgery and the special nursing rooms), labs, workshops, airflow required should be determined in conformity with regulations concerned.
