Abstract:
There is necessity of cooling in rural areas of developing as well as developed countries
having a large proportion of people living there, and in these locations, grid electricity is
presently unavailable or not reliable, and availability of fuels are also difficult or too
expensive. In order to obtain storage of vaccines and lifesaving drugs, food preservation and
grain storage, refrigeration systems based on usage of solar energy can be considered to be
the optimal solution for such areas which receive high solar insolation. The solar
refrigeration can be expected to play a significant role in meeting the needs of people in the
rural areas of developing countries for refrigeration. The improvements required are mainly
in the areas of increasing system performance and lowering costs. With probable increase in
the costs of conventional energy sources, it is expected that solar technologies will become
competitive with the conventional system in future.
