摘要: During most hot period it is possible to obtain passive cooling by decrease of surface temperatures with airflow velocities caused wind, entering interior the effect pressure difference through openings during time intervals when outside air cooler than interior. This turns inversed temperature more interiors. Shading devices used protect from unwanted solar radiation acting on surfaces change effects interiors according their types. The changes in volume flow rates, and amount can be advantageous or disadvantageous for total loads interval as day. Determination combined shading device efficiency protection strategy natural ventilation, will give opportunity designing optimum device. In validation different types alternatives, zone gains losses convection, sensible gain windows specific are compared. Cooling load calculations run energy analysis simulation program Energyplus using heat balance calculation method. Convection coefficients, exhibiting which calculated datas velocity measurements performed wind tunnel a model 4 without Heat opaque considered output convection. As opening dimensions directly related required expressed discharge coefficients obtained measured front differences between back all alternatives. Shaded unshaded areas occuring facade alternatives considered. All these parameters process. For every simulations had been done open window closed order emerge airflows times changing devices. situations classified follows; Closed window, no device, 1SIM3kap.pen; parallel 90 ο slat angle ground, 2.1SIM5kap.pen; 45 2.2SIM9kap.pen; perpendicular facade, 3.1SIM12kap.pen; 3.2SIM15kap.pen, Open 1SIM3ac.pen; 2.1SIM5ac.pen; 2.2SIM9ac.pen; 3.1SIM12ac.pen; 3.2SIM15ac.pen, 3 components evaluated 01:00-07:00, 08:00-18:00, 19:00-24:00 made situation 1.
