In the area of the application of renewable energy (solar) to refrigeration, An experimental solar, diffusion absorption refrigerator driven by two modules of flat plate solar collectors and working on methanol as refrigerant and a mixture of Lithium Bromide and Zinc Bromide as an absorber was built. Performance tests were carried out to determine the performance of the vapour bubble pump for the natural circulation of refrigerant – absorbent combination in the system.
