A simple solar energy powered intermittent absorption refrigeration system was designed, fabricated and tested. The system uses a generator charged with ammonia and water. The heat source is a solar radiation collector that collects and radiates solar thermal energy onto a black body generator. The generator drives the refrigerant around the system through a condenser and an evaporator. The system was evaluated by leaving it outside under solar radiation and monitoring temperatures at various points inside the collector, the generator, and the evaporator through the use of thermocouple sensors. The average highest and lowest temperatures inside the solar collector were 100°C and 40°C respectively. The average lowest refrigeration temperature was 4°C. The coefficient of performance (COP) of the system was estimated at 0.487.
