Abstract: A prototype Compound Parabolic Concentrating (CPC) solar energy collector for a sorption refrigerator is presented. It consists of two CPC reflectors, two absorbers and a single glazing cover. The absorber is made with seamless steel tube covered in a selective surface (absorptance: 0.95) and contains aluminium fins, activated carbon and ammonia. The parabolas are manufactured from aluminium foil and a reflective microfilm is bonded on its surfaces to provide high solar reflectance (0.95). The concentration ratio of the collector is about 2.4 and corresponds to an incidence half angle of 25°. A numerical model of the absorber is described. Simulations with a daily solar radiation corresponding to tropical areas are presented.
