چکیده
A comprehensive thermodynamic analysis is used to characterize the exergy destruction rate in any part of the solar air preheating system (SAPHS) and calculate its efficiency. The system consists of a solar evaporator, a heat exchanger to air preheating and an auxiliary pump. A computer simulation program using EES software is developed to model and analyses the SAPHS. The system provides preheated air during the year.
The thermodynamic analyses involves the determination of effects of air preheating (APH) heat exchanger pinch point temperature, solar radiation intensity and overall heat loss coefficient of the solar evaporator on the performance of the SAPHS. The result showed that the main source of the exergy destruction is the solar evaporator. In the solar evaporator, 115.9 kW of the input exergy was annihilated. Other main source of exergy annihilation is the APHHE, at 7.45 kW. The overall energetic and exergetic efficiencies of the SAPHS were 70.11% and 9.766%, respectively.
