SOLAR-POWERED ADSORPTION CHILLER WITH CPC COLLECTION SYSTEM: COLLECTOR DESIGN AND EXPERIMENTAL RESULTS
A new class of compound parabolic concentrator (CPC) useful in solar, solid sorption cooling is presented. The main feature of this class of CPC is that only a portion of its tubular receiver is exposed to sunlight. During the daily phase of the refrigeration cycle the non-exposed portion is covered with a thermal insulation, which is removed at the beginning of the nightly phase, in order to improve the natural cooling of the sorption bed. Geometric characteristics of the proposed CPC are given as a function of the concentration factor and the fraction of receiver area which is exposed to radiation A prototype of chiller using this type of collector and the activated carbon – methanol pair is described. The concentration factor is 1.41 and the receiver area is exactly half exposed to sunlight. The prototype was tested in Burgos (Spain) and the measured solar COP ranged from 0.078 to 0.096.
