e) The main ventilation system duct work should be
oversized as follows:
(1) The main duct run should be sized for 100
percent of the fireplace compartment ventilation.
(2) The intake and ductwork for each of the two
fireplaces, bilge and hull, should be sized for 100 percent of
the fireplace compartment ventilation. The manual damper for
each of the two intakes should be set to exhaust 826 m /min) at
316 degrees C of exhaust gases.
(3) The intakes and ductwork for the
and emergency corridor exhaust point should each be
sized for 25
percent of the fireplace compartments ventilation.
damper for each of the two intakes should be set to
207 m /min) at 316 degrees C of exhaust gases.
(4) Ventilation exhaust equipment and systems
should be designed and selected for continuous operation at
399 degrees C.
equipment in the instructor's station is expected to add 11 237
6629 W in the operator station and 4608 W in the electrical
room. Design for five people in the instructor's station rooms.
One staging area should be heated during the unoccupied times.
The staging area should be designated as a hose drying area
where wet hoses can be stored until the next training session.
18.104.22.168 Cooling Spray. Cooling spray nozzles should be
located above the grating ceiling aimed to direct water on the
mockups. The single water supply pipe leading to the nozzles
should have a motorized valve with a manual bypass controlled
from the DTC. The cooling will be activated between exercises
whenever the training compartment becomes too hot. The cooling
system should not be part of the training scenario. Each
cooling spray nozzle should have a constant dripping of water to
cool compartment walls. Refer to par. 3.8.3.
