I need inforamtion on a useful heat pump

I need inforamtion on a useful heat pump

(OP)
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.

RE: I need inforamtion on a useful heat pump

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

Happy hunting!!
