The Simulation And Analysis Of Thermal Characteristic Of Double Skin Facades

Double skin facades can bring beautiful architecture outline, comfortable indoor environment and good effect of energy saving. Nevertheless, the design of double skin facades is a complicated job which needs to consider many factors synthetically. If only we know its energy saving performance, we can correctly design a system of double skin facades meeting the local climate well.In this paper, the double-glass curtain wall and energy-saving thermal process is analyzed by the double glass curtain wall of noise, noise, ventilation and the energy-saving properties, the thermal channel wall of the simple mathematical model, listed under stable conditions of the heat balance equation. And CFD numerical calculation based on principle, Fluent simulation software using the single-floor double glazing simulation study NEW K-εturbulence model to simulate the thermal channel air flow. Through the different drafts access channel height and the width of thermal contrast to the simulation analysis, come alone floors double glazing wall in the design height of not more than 3.5m, Design should try to avoid greater than 1.6 m width of the glass curtain wall, the best design for the width of 1.4m. access to drafts height to 0. 35 m or so. Meanwhile, in the summer, heat Channel sunbreaker to be significantly lower in the envelope heat reduce the air-conditioning energy consumption of buildings.In the double glazing simulation analysis, consider the double glass curtain wall and HVAC design specific combination cited four examples, tall building should come as air cavity is divided into several parts, using layers independent systems, which minimize the impact of seeing all levels, also avoid the air cavity different altitudes too high a temperature gradient. This is the double glass curtain wall in the theory and performance analysis done, and the combination of specific examples, A preliminary study of the curtain wall and HVAC integration strategy, designed to study the reality has some significance.
