梭形翻板太阳直射辐射传输计算模型及实现
Calculating Model of Solar Direct Radiation Transporting Through Shuttle Louvers and Realization
摘要
Abstract
Firstly,two adjacent shuttle louvers were taken as the research object,the new model employed analytical method to analysis the fraction of beam radiation passing directly through the louvers,specular reflection fraction of beam radiation using the number and direction of reflection based on ray-tracing method,and net-radiation method was used to analysis diffuse reflection fraction.Secondly,based on the model analysis,the calculating program of solar direct radiation was developed with the MATLAB software to describe the shape,size,tilt angle and surface optical properties of shuttle louvers.Finally,the errors of the traditional calculation methods were analyzed,and found that "flat hypothesis " model would overvalued results of solar transmission,especially when the opening is directly facing the incident beam radiation.And the relative error is 5 % or more for the rest situation.关键词
