Decision support to conceive optimized transparent transpired collectors (TTC)

Abstract

This research work focuses on the preconception and optimization of transparent transpired collectors (TTC) for preheating air in buildings. To achieve this objective, a theoretical approach based on the developed physical model was adopted to simulate the behaviour of TTC. The daily time evolution of the intrinsic parameters of the concerned solar collector are evaluated in order to analyse their impact on the performance of TTC. The optimizationwas carried out through the variation of the design geometrical parameters such as pitch diameter and pitch holes to maximize both the collector energyefficiency and the recovered heat rate, and thisway, minimizing the temperature difference between the incoming air and the outgoing one. To reach the goal, desirability functions have been defined and implemented for the search of the optimum candidates of design parameters. In the context of our study case, an optimized pair of design variables (holes diameter and pitch) is proposed.
