Roof Heat Energy Recovery Fresh Air Ventilators Purify PM2.5
Energy recovery ventilator with PM2.5 purification function, improving air quality and health
1. Choose the proper installation types based on the building structure
2. Determine the fresh airflow required according to the use, size and number of persons
3. Select the right specifications and quantity according to the determined fresh airflow
Example
The area of a computer room is 60 sq. meters (S=60), the net height is 3 meters (H=3), and there are 10 per-sons (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=700(m3/h)
If it is calculated according to “Air changes per hour”, and assume that: P=5, the result is
Q2 =P*S*H=5*60*3=900(m3)
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 re-quired should be determined in conformity with regulations concerned.
