Research on Passive Solar Ventilation and Building Self-Sunshading

摘要

Strengthen heat insulation, prevent heat, reasonable decorate a building group, the nature of the room is ventilated wait for a method with setting window sunshade, try to be applied integrated, will surely get the favorable result that prevent heat. This study focuses on how to achieve natural ventilation and shade for energy saving by using of passive solar ventilation technology combined of building self-shading technology in building design. Simulates and analyses the velocity and temperature fields inside the external respiration double skin facade of a building. This research was carried out at CFD FLENT software, and heating load of Solar are calculated by using the Solar Load Model of FLENT, different forms of glass curtain wall combined with sunshade are calculated in physical model. All-year hourly dynamic heat load, ventilation and Indoor Dynamic Thermal Environment are calculated based on the hourly calculation results and detail analysis, which will provide useful guidance for using of solar passive ventilation technology combined of building self shading technology in building design.
