Absorption Refrigeration Cycle 1

[JLW]

Does anyone know of a good reference for the design of an
absorption refrigeration cycle?

I'am designing a small cooler and because of size constaints
am unable to use a compressor.

Evaportor temp: 32F
Ambient room temp: 75F
Cooling capacity: 200 BTU/Hr

Thanks,

JLW

Why dont you use thermoelectric cooling for that small load? It is simple and reliable, kind of the opposite of absorption.

I don't know much about cooling loads this small, but with water chillers in the 500 to 1000 ton range, absorbers are physically very large as compared to centrifugals or screw machines of the same cooling capacity. If you don't have room for a compressor, I'm not sure an absorber will help much in that regard. The units I'm familiar with have water as the refrigerant. Unless there's another style (and there could be), you won't be able to get anywhere near 32*F. Even with chilled water ouput temps near 40*F, the refrigerant water isn't far from the freezing point. One little blip and it'll freeze up.

Thanks for the input, I think I'll persue thermoelectric cooling for this application. Melcor looks like they have some products that will suit my needs.
