Abstract

In this research, a Kalina system integrated with the parabolic trough solar collector is proposed to produce power-cooling load and power-heating load for summer and winter, respectively. The proposed system is modeled using the conventional and advanced exergy, exergoeconomic and exergoenvironmental analyses. Based on exergy modeling, in summer collector and in winter auxiliary heater are the worst components respectively with 19629 kW and 11561 kW exergy destruction rate while according the advanced exergy analysis the major portion of their exergy destructions are related to the endogenous part while the avoidable endogenous parts are zero. On the other hand, the avoidable exogenous subdivision of the collector in summer mood and auxiliary boiler for winter are signicant with values of 4492. 84 kW and 2676. 31 kW, respectively. From the viewpoint of economic, thermal storage tank with minimum investment cost rate (13. 24 $/h) has the maximum exergy destruction cost rate within 1724. 13 $/h and 1783. 37 $/h respectively for summer and winter while the collector. Advanced exergoeconomic analysis indicates that the substantial portion of its avoidable part is exogenous indicating that the technological improvement of remaining components lead to the decrement of the exergry destruction cost rates of the auxiliary boiler. Moreover, the maximum value of the investment cost rate is related to the collector containing the maximum endogenous avoidable part with values of 646. 465 $/h for summer and 455. 015 $/h for winter. Similarly, in exergoenvironmental analysis, auxiliary heater with the lowest investment environmental impact has the maximum environmental impact associated with the exergy destruction with values of 242. 11 Pts/h and 306. 95 Pts/h respectively for summer and winter due to the utilization of the natural gas. Advanced exergoenvironmental analysis, the auxiliary heater has the maximum exogenous avoidable environmental impact associated with exergy destruction indicating the improvement of other components has a positive e ect on decreasing of its environmental impact.
