Study on Heat Transfer of Solar Composite Wall
In this article,heat model of solar composite wall structure was set up.Associated with three air flow patterns which refer to stillness,natural convection and forced convection,simulation on heat resistance of solar composite wall was emphatically carried out respectively.Compared with common wall without solar panel,it was found that there was significant increase in heat resistance when the interlayer air was in stillness or in natural convection,and the conditioning load was decreased remarkably due to the walls reducing heat gain.Besides,it was also found that,under these two conditions,the heat resistance was affected by interlayer temperature difference and interlayer thickness.However,when forced convection was taken into account,the increase ratio of heat resistance became lower and the influence of velocity and interlayer temperature difference and thickness became weaker.The optimum interlayer thickness of different interlayer difference in conditions of natural convection was given in this article.Compared with thermal retardation wall,it was shown that the whole efficiency of solar composite wall was better than that of thermal retardation wall.
