چکیده انگلیسی
In this paper after thermo-economic modeling of a solar heater using flat plate collector, the system is optimized. For this purpose, six variables are selected as decision variables. Then Particle Swarm Optimization algorithm is applied to obtain the maximum efficiency and the minimum of the total annual cost as two objective functions. The results of optimal designs are a set of optimum points, named Pareto front. The trend of variation in both efficiency and total annual cost with change in decision variables is also performed and the results are discussed. Mass flow rate as well as insulator thickness are found as two important decision variables which cause a confliction between objective functions. On the other hand, collector length has no effect on the confliction. To generalize the optimum results, the optimization of the system is performed for the different rates of heat transfer. The results reveal that, the efficiency is relatively changed for 0.123%, â0.740% and â1.506%, respectively in the cases of 0.5Â kW, 1.5Â kW and 2Â kW compared with the case of 1Â kW. The above changes for the total annual cost are obtained 44.30%, â40.98% and â77.87% which verify the thermoeconomic improvement in the lower rate of heat transfer.
