| Abstract | The Design and Development of a Solar Powered Refrigerator An ammonia-water intermittent absorption refrigerator with a 1.44 m2 flat plate solar collector has been constructed and successfully operated as a first step towards the development of a village ice maker. No oil or electricity is used, and refrigeration at night. a Regeneration takes place during the day Rapid absorption is obtained by means of new feature (first proposed by AWARTMAN, 1969) in which the heat of absorption is dissipated from the flat plate . In the generator 33 1b of solution containing 46% ammonia in water is used. On a clear day the solution temperature rises from 86 F to 190°F and 2 1b of pure ammonia are condensed at 90°F, refrigeration the temperature of the ammonia drops to 19°F. During The astimated overall solar coefficient of performance (cooling effect divided by solar heat absorbed) is 0.09, which through small compares with previously published works. It is recommended that a flat auxiliary mirror be used to enhance the solar heating of the generator, and that an expansion valve with dry evaporator coils be tested next. |
