Solar-power based sorption refrigeration systems do not suffer from the problem of greenhouse gas
emission and release of ozone layer depleting substances as in the case of conventional vapour
compression refrigeration system. Absorption based systems are already commercially available while
adsorption based systems are still in research and development stage. Progress and development of
solar-powered adsorption cooling systems have been described in this paper. Factors preventing
commercialization of this system have been discussed in detail. The state of the ongoing research, to
make the system more efficient and cost effective, has been presented.
