The system was evaluated with the ammonia/lithium nitrate/water (NH3/LiNO3/H2O) mixture. The system was designed to produce up to 8 kg/day of ice. The system consists of a Compound Parabolic Concentrator (CPC) with a cylindrical receiver acting as the generator/absorber, a condenser, an evaporator and an expansion valve. The system operates exclusively with solar energy and no moving parts are required. Evaporator temperatures as low as-11°C were obtained for a period of time up to 8 hours. Coefficients of performance as high as 0.098 were obtained. These coefficients were 24% higher than those obtained with the same system operating with the binary ammonia/lithium nitrate (NH3/LiNO3) mixture previously reported in the literature. The results showed that the developed system seems to be a good alternative for refrigeration in zones where electricity is not available.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
