Calculation Model of Solar Diffuse Radiation Transportation Through Shuttle Louvers and Program Realization

Abstract:

Two adjacent shuttle louvers were first taken as the research object, the calculation model of solar diffuse radiation transportation through shuttle louvers was established. Based on the model analysis, the calculation program of solar diffuse radiation was developed with the MATLAB to describe the shape, size, tilt angle, and surface optical properties of shuttle louvers. Then, the correctness of the calculation program was verified, and the sensitivity analysis was carried out on the partition number of shuttle louvers. Analysis results show that the relative error rate decreases with the segments, but changes no more if the partition number is over 8. Finally, a comparative study of the error by the proposed method and that by traditional methods with flat hypothesis model shows there exist the error increases with the tilt angle.
