G'day Craig,
Love your work, all those things you had mentioned are things that I =
have not considered in great depth up to this point. Looks like if I was =
to put a canopy on the pit. I will be jumping into a real deepend. This =
weekend I was just drawing up plans for the hull and how I will have to =
construct it differently if an enclosed canopy will be place ontop. Do =
you think its worth while to be paranoi (like myself) to worry about all =
these things so early on...or should I just go ahead and build the damn =
thing up then I can get some realistic measures of T and RH inside the =
pit. Then I can figure out if I need some sort of active cooling?
The window air conditioner option is definetly out. I live in a place =
where I wont even dare to stick a satellete dish out the window, it will =
get knock off too easily. So my only mean to cool this room down is the =
option of one portable air conditioner or evaporative cooler that does =
not include an outdoor component to function.
=20
Thanks for making this sophiscated concept relatively simple to =
understand.
=20
I will shot you a private email asap.
Cheers,
Albert
p.s. Gene, I think this is definetly a good topic article for the =
simpits.org site. What do you reckon?

Finally a question I'm qualified to answer. :) I do a lot of HVAC in =
my work.
=20
Before you decide on cooling you should consider ventilation first. =
Your pit is basically a small room in a larger room. Here are the basic =
details to evaluate:
1.. What AC and or ventilation do you have in the room the pit is =
in? I.e. room size, AC air flow rate, AC air supply temperature(out of =
duct).=20
2.. What outside air conditions, Temperature(T) and Relative =
Humidity(RH) does you location see summer/winter?=20
3.. What clothing and/or helmet and mask equipment will you use?=20
4.. If you use a "oxygen mask" where will the air come from and =
where will it exhaust?=20
5.. How much heat will be generated by the equipment in the pit?
The RH is a very important parameter that is often overlooked. The =
simplest way to get rid of the humidity and heat generated by you and =
the equipment is to exhaust it out. What goes out must be made up =
"Outside Air Make-up"(OA) and this must be cold enough and dry enough to =
provide a T and RH equilibrium that is comfortable. IF the room's air =
is good enough to provide sufficient OA to the pit all you need to do is =
have an exhaust system(simple fan) with vents located to direct the OA =
air through the pit.
=20
If you room is too warm or humid to knock down the T/RH of the pit, =
then active cooling is required. If cost is important and you're =
handy(if you can build a pit...) I'd use a regular window air =
conditioner and build a shroud around the "evaporator" section, the part =
that goes outside the window. The shroud would be connected to a fan to =
blow the air outside the room through the bars. The room-side of the =
air conditioner would be directed to the pit's OA make-up.
=20
I'd be glad to provide assistance in determining the details if you =
wish.
=20
Craig R.

Hi guys,
This is a question especially for those of you who have or planning =
on building an enclose cockpit (especially for the f16), i.e. with a =
canopy. How do you deal with temperature that will bound to build up =
within the pit?
=20
Heat generated from all the electronics, backlid panels, extra =
monitors (If you are not using a projector) and your own body heat
The only reason why I want to have a canopy is not for aesthetic but =
for "Sound proofing" myself when I talk over RW (because I share room).I =
dont want to "premanently" sound proofing myself by suffercating myself =
from within the cockpit. Turning the pit into a coffin :)=20
To make matter worse I live in a flat where I cant break any walls =
to put in a ducted reverse cycle air cond... I have grills and bars on =
my windows to keep out intruders so no way I can put in a wall/window =
mounted air cond. My only hope would be a portable air conditioner or =
one of those evaporative coolers...modify it and throw an inlet into the =
pit.
My second question would be, evaporative coolers, are they any =
effective in cooling the inner space of the f16 pit? because the price =
of one of them is like 1/10 of a portable air conditioner.
Would love to hear all of your thoughts :)
