Exergoeconomic analysis of a solar assisted tea drying system

Abstract

In this study, an integrated system which consists of a batch type tea dryer and a PV/T unit is developed and analyzed through the exergoeconomic approach. The EXCEM method based on mass, energy, exergy, and cost balances is performed to find out the exergoeconomic performance of the drying system. The parametric studies are used to see the effect of changing properties utilized in the system on performance. The results of the present study show that the capital cost and the capital productivity of the system are $5953 and 1.54, respectively. The energetic and exergetic loss ratios are calculated as 76.45?MJ/$ and 72.63?MJ/$, respectively. The exergy efficiency and exergy destruction for the whole system are found to be 74% and 201.6?GJ, respectively.
