/T collectors, absorber plate parameters, and absorber configuration design types are extensively discussed. Exergy analysis shows … that the coverless PV/T collector produces the largest total (electrical+thermal) exergy. Furthermore, PV/T collectors are …

between exergy and Second Law efficiencies is not clearly recognized by many. It is attempted here to clarify the definitions … and use of energy and exergy based performance criteria, and of the Second Law efficiency, with an aim at the advancement …

considering the heat/exergy loss to the environment. For the criteria without considering the heat/exergy loss to the environment … the heat/exergy loss to the environment is taken into consideration, the first and second law efficiencies display the … performance: one is to improve the heat/exergy input; the other is to enhance the heat-work conversion ability of the system. The …

. Parametric optimization is conducted by means of genetic algorithm (GA) to find the maximum exergy efficiency. It is shown that … system can reach the maximum exergy efficiency of 60.33% under the conditions of the optimal slope angle and hour angle. …

based on the exergy method is introduced to evaluate the system performance, exergy loss of each component and total exergy … process and non-dimensional exergy loss of each component are analyzed in detail. The results show that the performance of the … temperatures. Exergy losses in the expansion valves, pump and heat exchangers, especially refrigerant heat exchanger, are small …
