I need inforamtion on a useful heat pump

[DanTheMan]

I am looking for information on heat pumps. I have an industrial aplication where a heat pump could save us a lot of steam and cooling load by moving heat from one place to another. We were looking at ammonia-water absorption heat pump systems so we could use a pump instead of a compressor. So far we have only been able to find limited info on these systems (specifically heat of absorption) and I was hoping someone out there had some info that could help. We are operating between 0-50psig, and 140-220F, if there are other refrigerants that would work better for this I would enjoy hearing about them too.
Tanks in advance.

You should really try google. I used your own "search phrase "ammonia-water absorption heat pump" and came up with about 400 references.

The top one:

http://rclsgi.eng.ohio-state.edu/~christ-r/ceat/theory/theory.html

will run you through the basic theory. Looks OK but no fancy graphics and they dont sell the units.

Best Regards

Thanks, I must not have been as specific as I should have when I searched because I didn't come up with many useful links. I was looking for more in depth data if I could get it. I am familliar with the cycle, just not all of the particulars and pitfalls.

Dan:

Got to Trane.com and seach first for "Absorption Chillers" and then "Heat Pumps".

They have all types of both: single stage, two stage and DFA AAbsorption as well as closed and open loop heat pumps.

All sorts of sales, applications, case studies, service and selection info as well
