What is the air change rate (ach) for a 100 ft^2 (9.3 m^2) space with a 10 ft (3.0 m) ceiling and an airflow rate of 200 cfm (95 l/s)? a. b. c. 2 6 12

The ACH is 12/h

Solution:

As per the question:

Area of the space,

Height of the given space, h = 10 ft

Air flow rate,

Now, to find the Air Change Rate (ACH):

We calculate the Volume of the given space:

Now, the ACH per min:

=

Now, ACH per hour:

=
