| Abstract: |
Studies have been made of the intennittent zeolite-water and charcoal-methanol adsorption
refrigeration systems for possible use in solar powered cold storage units in tropical rural areas. A
commercially made intennittent zeolite-water refrigerator was tested and found not to perfonn well,
possibly due to damage in transit. Attention was then directed to the experimental detennination of
charcoal-methanol adsorption properties using activated carbon samples imported from the United
Kingdom and samples made in Thailand. One of the imported types of activated carbon was then used
in a solar refrigerator designed, constructed and tested in the Asian Institute of Technology.
The solar collector, of area one square metre, contained the activated carbon from which methanol
was distilled by day and onto which methanol was readsorbed at night. The perfonnance of the solar part
of the system exceeded our expectations. The unit was able to produce 4kg of ice at -4°C by the
evaporation of the distilled methanol after a clear day. An economic evaluation suggested that such
refrigerators could be less expensive than solar photovoltaic refrigerators currently used for vaccine storage
and freezing ice packs in remote areas. | |||
