Through a HVAC contractors book I found out that salt water systems
are used for many large buildings to chill water for pumping through
forced air radiator systems, however they have fallen out of favor
because of their tendacy to clog up.  Someone would need to check the
evaporator section daily for clogs, and break them up if they formed.

Absorbtion Cooling is an area where I've been looking for information.

I've been interested in because it seams like it would be a good way to
provide low energy cooling for an RV.  Unfortunatly I haven't been able
to find any info on the actual process other than sketchy write ups giving
the overall process, but none of the engineering details.  Are there good
articles or books on the subject? If so, I'd like references so I can
look them up.  Also manufacturers that make absorbtion cooling devices like
refrigerators and whole house AC units.  One of the things I'm really
interested in is the actual tempeture needed for the heat source?  The reason
I'm wondering about this is because in my RV design I'm using a hot water
boiler for heating and hot water.  Also as much waste heat as possible
from the engine and generator will be dumped into the boiler's tank. 
Is 180-200 F temp water high enough for the heat source in an ammonia
absorbtive air-conditioner?  What is high enough?  Are there chemical
combinations which will work with a 180-200 F heat source?

Thanks in advance.
