Question 23/55
The following information refers to the diagram above.
The following information refers to the diagram above:
* The room is an Airborne Infection Isolation Room with a series anteroom.
* The room volume is 960 cubic ft. (27 cubic m).
* The room cooling load is 4,000 Btu/hr sensible only. (Ignore latent loads.) (1172 W)
* The supply air temperature is 55° F (12.8° C), and the room temperature set point is 75° F (23.9° C).
* The toilet exhaust is 100 cfm (47.2 L/s).
* The total room envelope leakage area is 35 sq. in. (22.575 sq. cm), (A_L).
* The anteroom supply air volume is 75 cfm (35 L/s).
* The design pressure difference complies with FGI Guidelines (D_p) (in. water/kPa).
* The room air flow difference (Q_d) is defined by the following:
Q_d = (7p)^0.65 x A_L / 0.019564
(SI) Q_d = (7p)^0.65 x A_L / 10,000
Based on the diagram and the information above, what is the MINIMUM design room air exhaust volume?
