[Digestion] AC compressor on engine for chilling

[Zietsman, Rex]

Stan,
Have you tried buying an absorption chiller? We have been quoted $100k
for a 400kW chiller by York. These machines, while conceptually a good
idea, are simply off the cost scale. The next best thing is to use a
fridge design. That is a lot more difficult to install and make to work
than bolting an AC compressor onto a motor that may already have the
bracket for it and the pulley to provide a V-belt drive. If you have a
neat way of going the absorption chiller route, I am all for it - gimme,
gimme!

Gentlemen,
Regarding the water based CO2 scrubbing, wouldn't this give you methane
that was saturated with water vapor?  I'm not sure what this would do in
an engine.  Maybe cause icing in your carburetor?
The beauty of absorption cooling is that it is driven primarily by low
quality (thermal) energy rather than expensive shaft power or
electricity. Hence you could make electricity with your methane and then
use the waste engine jacket and exhaust pipe heat to create cooling.
Have your cake and eat it too.
