mensa" ventilation system with heat recovery, v = 5 500 m 3 / h exhaust air via 7 exhaust grille
To encourage air mixing, the exhaust grille
should be located at a point remote from supply.
At present, patient wards with mixing ventilation usually have an exhaust grille
installed in the lower part of the restroom door, and some air is extracted through the grille to keep the restroom at a lower pressure than that in the wards.
The air supply from the diffuser in the index patient's cubicle had the highest supply flow rate (336 L/s), while the adjacent exhaust grille
had the lowest exhaust flow rate (87 L/s) among all four functional exhaust grilles
Figure 1 (previously published in my February 2014 column "Restroom Exhaust Systems") shows a computational fluid dynamics (CFD) simulation of a typical exhaust grille
After closing the exhaust grille
doors, you need to secure them in place with the 100-600 lb-ft torque wrench, NSN 512001-113-9564, from your TM's additional authorization list.
With air-scoop gills, wacky hockey-stick tail-lights and a pepperpot rear exhaust grille
, it's butch, brawny and brazen.
420 m spiral seam pipes made of galvanized steel sheet DN 100 - DN 400, - 77 pieces moisture-guided exhaust air elements with intensive ventilation, - 3 pieces exhaust grille
for pipe installation, - 66 pieces Fire protection ceiling scoops, - 14 pieces throttle valves DN 160, - 77 pieces Telephone sound attenuator DN 100, - 8 pieces of pipe muffler DN 200 - DN 400.
This study demonstrates that the supply airflow paths, induced airflow paths, and exhaust grille
placement can work collaboratively to establish protective and effective contaminant control.
Also, fumes from the engine compartment that would normally be vented through the exhaust grille
are forced into the driver and crew compartments.
In February's Engineering Notebook column on restroom exhaust, I agree with Steve Taylor's approach in making a seemingly simple element such as restroom design better by looking at the exhaust rate, the exhaust grille
quantity and the makeup air design.
The smoke plume from the gun's discharge is removed by the up range exhaust grille
, while the airborne debris from the bullet's impact is removed from the downrange exhaust grille
to maintain range visibility.
