Performance of an intermittent refrigerator operated by a flat-plate collector

Abstract A simple form of intermittent refrigerator incorporating a flat-plate collector, five feet by three feet six inches, has been tested. Values for the actual coefficient of performance have been obtained, and compared to the theoretical values. The performance of the flat-plate collector has been analyzed, and figures obtained for the effective cooling produced per unit area of collecting surface. The tests were conducted at Colombo, Ceylon.
