РАСЧЕТ ПАРАМЕТРОВ СОЛНЦЕЗАЩИТНЫХ УСТРОЙСТВ

Abstract

Questions of overheating of premises at the expense of solar radiation in various regions of the country are considered. The assessment of the existing normative documents on design of solar control and shading devices is carried out. Are shown absence in them effective methods of calculation of optimum carrying out of the shading elements of solar control and shading devices. Methods of calculation of parameters of the main types of solar control and shading devices (SCSD) in the form of awnings, vertical and horizontal lamellae established before fenestrationareoffered. Methods consider orientation of windows, a trajectory of apparent motion of the sun on the heavenly sphere, the latitude of the area, a power component of solar radiation. Are brought numerical an example of calculation of parameters of solar control and shading devices and the recommendation about effective use of solar control and shading devices in the form of awnings, vertical and horizontal lamellae. Calculations and the analysis of protective characteristics of SCSD are carried out that allows to create preliminary recommendations about efficiency of the SCSD various types. Solar control and shading devices in the form of stationary awnings both continuous, and trellised will be effective only at high values of heights of standing of the sun. With average heights of the sun and furthermore with low heights stationary awnings become not expedient because of disproportionately big carrying out. SCSD in the form of blinds with horizontal and vertical arrangement of the lamellae located are more effective as it is perpendicular to a wall surface, and under some corner to it. Recommendations about effective use of different types of blinds depending on orientation of fenestrationare provided in article.
