Since I no longer enjoy access to the labs at H-B,

I've been gathering some useful tools up to enhance

our development in the 'Connection's shops. I picked

this temperature chamber up off Ebay a few weeks ago for

$150 and paid another $150 to have it shipped!



It's a little bigger brother to the very first

chamber I bought at Electro-Mech about 30 years

ago! Had to do a some work with door seals,

CO2 plumbing and much scrubbing with 409 and

acetone but it cleaned up pretty well. Just

got it operational and tested. Gets down

to -60C in about 20 minutes, back up to 80C

in under 15 minutes and controls to within

2 degrees C.

I think it will do for the moment to get some

work out for a customer this weekend. I've found

a modern digital device to replace the analog

heating/cooling controller. I'll replace the Fluke

portable thermocouple readout with a permanent digital

display and selector switch for about 5 channels of

thermocouple. I need to build a CO2 valve-open

timer so that I tell when a bottle is about to

go empty. This thing uses the liquid CO2 from bottles

with dip tubes. They're essentially constant pressure

until the liquid runs out whereupon you loose cooling

very quickly. But by monitoring total valve-open time

I can get a pretty good calibration on pounds of

CO2 consumed.



Hmmmm . . . wonder if I need to hit up Mr. Gore

for some carbon-credits. I'm going to dump about

100# of CO2 this weekend. Maybe I'd better get

him to plant some trees for me or something.



I'd forgotten how heavy those bottles are! I

think I'll run a hard line from the garage down

to the basement shop so I don't have to lug them

on the stairs! I'm getting too old for that kind

of work!



You can even warm TV dinners in it!

That rig should be very benificial in testing componants. Great buy Bob... Now for some comedy... If you do heat up TV dinners in it and you get the runs from bad beef does one need to purchase a new rectumfier or just recaliberate the old one ??  :< ))..........

Bob,

        I'm sure you are providing proper ventilation for the CO2  that

leaks out.   I'm not sure but the CO2 may be heavier than regular air and

thus puddle in low places  (basements).  Don't need you to be room temp

for any time soon.  We need your wit and knowledge to help us battle the

electrons and keep them in their place.

If planting a young tree earns carbon credits, then not cutting down an 

old tree should be worth even more credits. I have a few thousand pine 

trees that I promise not to cut down. You are welcome to apply those 

credits to your temperature chamber.

Now if you really need to cool down your beer in a hurry you could try this

New Zealand "bloke's" approach http://www.asciimation.co.nz/beer/. It's a

little noisy (125db) but seems to work quite well !!



Cheers.

   Hmmmm . . . I'll throw a thermocoupled can

   in the next low temp run and see how cold it

   gets. Typically, we drop to -60C and soak until

   surface of test article gets to -55C. Most

   of the gizmos I test will get down there in

   30 minutes or so. The atmosphere in the chamber

   is stirred with a fan so a room temp beer just

   might get pretty frosty in that time.



   Dr. Dee likes her beer with ice crystals in

   it. It takes 45 minutes to an hour to arrive

   at her favorite condition in a -10C freezer.

   I'll conduct the experiment, record the results

   and report on the findings.

You are dumping pre-existing CO2 - not making more of it.  Carbon 
	


credits apply to a process that creates CO2 from a source where carbon 

is previously trapped, chemically or otherwise.  Granted, compressing it 

does take energy, but probably not any more than using a refrigerated 

environmental chamber rather than one cooled by CO2.

Please be very careful of using CO2 for cooling in a basement shop 
	


unless it has a floor level access to the outside to allow the CO2 to 

escape.  CO2 is heavier than air and will collect in the basement otherwise.

   Yeah. I run the fan to stir the shop air and

   spread it out . . . A typical test cycle of

   an hour of cooling takes about 10 pounds of

   CO2 and that's pretty well stirred up as we

   go.

I'll just promise not to exhale on alternate breaths. If that doesn't work,

well, reduce co2, kill a mammal.

We once developed a device that had designers in Switzerland and the US. Whenever the power supply in the device was tested in Switzerland it passed all tests in the environmental chamber. When tested in the US it flunked due to a load resistor that would overheat an output filter capacitor in a purchased UL/CSA/IEC/TUV power supply. The prototypes seemed to be in Fedex transit permanently and accusation flew, and schedules flew too...out the window. The Swiss environmental chamber was super-high tech and had powerful mixing fans to make sure that nothing in the chamber deviated from anything else by more than 1/10 degree. 



The power supply worked very well inside the chamber. But no place else.
