TOWARDS A ONE TON PER DAY SOLAR ICE MAKER

There is a need for heat operated refrigeration systems in areas of th e world which have a warm climate and also have no firm electricity su pply. Research is underway on carbon - ammonia refrigerators driven by the heat of steam condensing in a thermosyphon heat pipe. The heat so urce can be solar energy, biomass, or some combination of the two. Res ults of heat transfer tests on an experimental generator are presented together with future plans.
