Description

Ventilation of a room may be described in terms of room air exchanges and air flow.


 

Parameters:

(1) room size in cubic feet

(2) number of room air exchanges

(3) air flow in cubic feet per hour

 

room size in cubic feet =

= (width in feet) * (length in feet) * (height in feet)

 

air flow in cubic feet per hour =

= (room size in cubic feet) * (number of room air exchanges per hour)

 

number of room air exchanges per hour =

= (air flow in cubic feet per hour) / (room size in cubic feet)

 

room size for a level of ventilation in cubic feet =

= (air flow in cubic feet per hour) / (number of room air exchanges per hour)
