Summary

A solar-powered solid-absorption refrigerating system is being developed for use in areas where the complexity of conventional refrigerating systems is impractical, but solar energy is abundant. An initial investigation showed that a solid absorption process
offered the best compromise between simplicity of the system and a reasonable coefficient of performance when operated with flat-plate solar collectors. An experimental investigation of the absorption and desorption of ammonia in calcium chloride and
strontium chloride was carried out to establish suitable design parameters. To serve as a demonstration plant a small drinkingwater cooler with a 4 m2 collector area was built. On a clear day in Denmark an overall coefficient of performance of 10% was obtained, corresponding to an ice production of 6 kg m-2 of collector area. The demonstration plant is presently being treated at the University of Khartoum.
