建筑表面应用冷却涂料的数值模拟
Numerical Simulation of Cooling Coatings Applied to Architectural Surfaces
摘要
Abstract
In view of a further inquiry into the impact of the applied high reflective cooling coatings on the external envelope of buildings on the wind and thermal environment of architectural blocks,a numerical simulation has thus been made of four different coating methods of building envelope applied coatings by adopting computational fluid dynamics(CFD)method.The research results indicate that the surface temperature of the building is under a significant effect of the cooling coatings.When the wall absorption rate decreases from 0.85 to 0.10,the wall temperature directly exposed to sunlight can be reduced by up to 15℃.However,for shaded areas not directly exposed to the sun,the temperature actually increases by 1.0~1.5℃.There is a variation of the impact of different coating methods on the environment as well.With roof coatings applied,the temperature of the pedestrian layer rises by about 0.2℃,and the average air age increases by 2 seconds compared to that under a no-coating condition;with the wall paint applied,the maximum temperature drops at pedestrian layer height is between 0.5 and 2.0℃,with the airflow velocity of the pedestrian layer height slowing down by 5%~10%,especially when the leeward wall is heated,the average air age of the pedestrian layer height increases by 4 seconds.关键词
