[Milsurplus] cooling systems/freon/R-12/R-34, etc.

[Patrick Jankowiak]

I find that the cheap consumer devices in things like coolers 
etc. are seldom cooled well to remove the heat, and often 
operated at their maximum currents, so that the individual 
'diodes' start to burn out. The units I have removed from 
military surplus gear is always over-cooled with larger fans, and 
seldon has burnt junctions.

I'd like to know how many BTU one of an 'off the shelf' deviced 
would remove for the same given temperature drop, humidity, and 
power used. One thing is certain, better get a 3KW alternator!

One of the other gents commented on moving away from liquid 
'refrigerants' to 'peltier' devices. Interestingly enough, that's 
one of the things I'm working on....for automobiles. Since I'm a 
thrifty guy, I'll ensure it's (relatievely) cheap and 
(semi)reliable. Funny thing - in order to legally retro-fit and 
experiment with a vehicle, I have to remove the existing 
refrigerant (and the rest of the a/c system) at an approved 
station...which has usually leaked out anyway... Bill KA3AIS
