Gas Absorption Cooling Info

Yahoo Message Number: 82375
Hi,

There has been plenty of buzz about gas absorption cooling units recently. All of it understandable given recent events with failures, fires, damage and disgruntled customers. The magazine Good Sam Highways did an informative article in their August-September 2012 issue on page 28 with the RV Doctor. I've updated my thread with this information
here:

http://www.muniac.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=68#Post68 For those interested, scroll to bottom post. I paraphrased some of the salient points for those not able to access this paper. We opted for a replacement cooling unit to keep our Norcold chugging along so I've added a few of my own impressions. The magazine article goes into refurbishing, rebuilding and re-manufacturing procedures which didn't strike a chord with us. The biggest drawback of "almost new" is who's doing the work. Results vary accordingly and a nice coat of paint can cover a multitude of sins. I think your best value comes from a small independent company that's in touch with safety, quality and its customers. In other words someone, that stands behind their product. In times of need who wants a menu and automated attendant layered within inaccessible departmental structure. Or reams of red tape that somehow excludes what the customer needs.

Please do check your absorber coils and vessel for excessive heating. An indication of poor chemistry flow and possible problems. For reference, our Pines RV Refrigeration cooling unit's absorber and vessel have remained just warm to the touch regardless of outside temperature. Our frig runs nicely on 7. Also grease the twist snap clips on your outside access panel for easy removal and to prevent premature breakage. Take off that panel and inspect things often. Stay in touch with your cooling unit and remember that safety is no accident.

Hope this information helps a few folks out there.

Best - Scott

'poor chemistry flow'
That is a new term to me. Scott, what is 'poor chemistry flow?'

Your inspection tips are right on.

Lee - I made a general reference to the mix of water, ammonia, hydrogen and associated vapors as "chemistry" flowing inside the piping. From the dictionary:

1. The science that deals with the composition and properties of substances and various elementary forms of matter.
2. Chemical properties, reactions, phenomena, etc.

Plus a little word smithing and creativity and voila! There you have it. A dry subject just begging for improvements. As mentioned, I hope it helps a few folks and provides some entertainment in the process.

"Degradation of Gas Absorption Chemical Processes' would be more acceptable. Your use of the word Chemistry turns a noun into an adverb.

Scott, sorry to come back to this but I now remember that the Gas Absorption refrigerator process is a 'physical' not 'chemical' process - gas-liquid-gas, etc. So the words 'chemical' or 'chemistry' don't even enter into the description.

'Poor physical flow' . . . not a bad, melodic ring, eh?

Ye Gods Lee, I struggle to learn about my coach on this group, English Language courses are a bit beyond me!

Lee - The point of the article is to pass along some helpful information. If one accident can be avoided then purpose served. The gas absorption process is a complex one beyond the scope of the article. That said, I do have some PDF links there about it for those wishing to delve deeper. I'm going to assert the article has value even though a few "terms" may be imprecise. As someone who flunked English, I doubt reaching literary excellence is in the cards for me anytime soon. But thanks for the critique, opinion and feedback. I always embrace the learning process.

Scott, I do appreciate your effort. Nevertheless, I do think there are many in the Group that do relate to the difference between a chemical and physical change. With all due respect, it is a high school science concept.

Well I for one sure care (sarcasm). The others are just too polite to say so.
