Ventilation Design And Selection

The required air volume of ventilation depends on the usage situation,created contamination within the room and

amount of heat needs to be extracted,calculated in various criteria and ways with following equation and tables

Required product QTY = Resonable air volume ( m³/ h ) ÷ Selected models of air volume values ( m³/ h )

Remark : Calculation of the required air volume has two methods as below ( m³ / h )

1. Using air exchange to calculate

V=RV*N

RV: room volume (m³)

N: number of air exchange hours(n/h)

2. Using per capita air volume to calculate

V=PV*P

PV:The required air volume for each person hours(m³/h)

P:Number of people
