Abstract

A comparative analysis between a parabolic trough collector (PTC) and a compact linear Fresnel reflector (CLFR) is presented. A mathematical model for each concentrator is developed, a computational algorithm in order to solve the rigorous mathematical model is proposed, and a numerical simulation exploring the critical variables that define the operational performance of both concentrators is done. According to the obtained results, it can be concluded that the parabolic trough solar collector has important advantages that makes it the best option to be used as a direct generator of an advanced solar-GAX cooling system. Its thermal efficiency is about higher than that of the Fresnel concentrator, therefore, the energy demand of the cooling cycle could be satisfied with a smaller equipment, if this concentrator is used.
