	Look under "absorption cooling" in books on heat pumps or
refridgeration design.
	They're not complicated (no moving parts), but not fast to cool
down either.   If you can do basic plumbing and pipe soldering you
should be able to build one (I'd suggest a Lithium Bromide with provision
to drain and refill to avoid freezing rather than playing with Anhydrous
Ammonia.)
