Experimental Study of Temperature Distribution and Heat Transfer Coefficient of Vertical Exterior Surface of A Building
摘要
Abstract
The variation of temperature and the heat transfer coefficient of vertical external wall of a building were studied.Experimental results showed that the temperature difference of the vertical external wall is affected by the building height, wind speed ,solar radiation intensity and air temperature.Through the multidimensional fitting to the temperature difference of the vertical external wall at different times and different height, the relationship is obtained: with the standard deviation of no more than 2.9 ℃.Besides, the wind speed and the height of the building have a certain impact on the heat transfer coefficient of the exterior building surface.The heat transfer coefficient of the exterior building surface was obtained by regression analysis.关键词
