Big Offgrid System Request for Guidance [RE-wrenches]

[Blair May]

Nothing like VFD/water cooled compressors, things sure have come a long
way in that field. Have a grocery store that heats H2o for flooring &
sanitation in winter then in the summer has a air cooled condenser. 2
large older 280rpm central compressors that are being changed out as we
speak. Good work!

by design (earth couple the building, super insulate, install ground

assist (look into the new aDsorption chillers) as Kurt suggested.  Super
insulate the walk-in cooler, etc. I did an energy conservation &
renewable energy plan for Sunrise Ranch Community in Colorado and we
came up
with a menu of 110 energy conservation strategies to reduce thier KWH
load 40% before applying PV or Wind.

We are remodeling a 1938 hotel in New Mexico and have been able to
project some rather impressive savings by carefully managing and moving
heat.  e.g. Specify all of the kitchen and bar refrigeration for remote
compressors, then feed these plus all of the walk-ins (including the
wine cellar) from a custom rack system with water-cooled condensers.
This removes heat and noise from the kitchen, dramatically lowers both
the energy load and the maintenance requirements on the kitchen units,
and 
provides hot water.  Oh, and the walk-ins are all located in an unheated
portion of the basement.

Very interested in what adsorption chillers you have used - I have been
working with a team that has installed several of the large Japanese
units and is working with some other players considering entry to the US
market.
