Thermal and Economic Analysis Review on Flat Plate, Parabolic Trough and Evacuated Tube Solar Collectors for Process Heat Applications

Chandraprabu Venkatachalam , Samuel G. Mariam and Abdi Chimdo Anchala

Abstract:
Energy plays a pivotal role in our society because of new life trends which are accompanied with high energy consumption. To meet these needs renewable energy technologies such as solar energy systems have proven to be advantageous in many ways. This paper presented a review of thermal and economic analysis of solar energy collectors and processes. Three non-concentrating and concentrating collectors have been analyzed, which includes flat-plate collectors and evacuated tube collectors from the first category and heat transfer enhancement from the second category. Initially, an introduction into the nature of solar energy was attempted followed by a description and working principle of all three collectors. This was followed by an optical, thermal and thermodynamic analysis of the collectors and a description of the methods used to evaluate their performance. Another important consideration for solar collectors will be the economic analysis, which includes the manufacturing, operation and maintenance costs, etc. Beside these, complexity, uniform flux distribution and working fluid selection of some other important factors in solar collector systems. Typical applications of the various types of collectors have also been reviewed and presented. Through the literature review, it is shown that exergy analysis gives a representative performance evaluation method and is emphasized as a valuable method to evaluate and compare possible configurations of these systems.
