摘要：The purpose of this paper is to investigate the thermal performance of such air flow windows in whichair flow windows integrate windows and ventilation system by drawing the fresh air through the cavity between thepanes before it enters the room. By the extensive CFD modeling it is shown that the method prescribed by the existingISO standard is inadequate in predicting the convective heat fluxes in the ventilated cavity. The transient method isimplemented in a program called Win Vent, developed in connection with this project. There is a large potential forlowering heating demands in buildings with exhaust ventilation by using air flow windows. The multi-node resistancemodel that is the ISO method is used for calculating the thermal performance for normal windows and air flowwindows vision area. The parameter (geometry, boundary conditions, and mesh generation, near wall treatment,turbulence model and radiation model) study is done by using the CFD model.
