Abstract
The aestival air conditioning load of the residential building envelops is affected by their own geometric and thermal parameters in the Yangtze Valley; however their influence factors are still unclear. This Paper mainly considers the parameters such as heat transfer coefficients of building envelops, area ratio of window to wall and shading coefficient. In virtue of the princi-ple of orthogonal test, it calculates and analyzes the aestival air conditioning load of the southern building envelops in the design situation, so as to determine the main influence parameters. For the southern aspect, the unit area load linearly increases with all the parameters. Among them, the area ratio of window to wall is the most important one, when it is greater, shading coefficient and heat transfer coefficient of the window have more dramatic effect, otherwise heat transfer coefficient of the wall do. By dint of the correlations of the wall-envelop load ratio and unit area load with the parameters, the energy saving potentials can be deter-mined and effective suggestions are provided for the energy saving measures for the building envelops in this area.关键词
