【摘要】 在太阳能的开发利用中,竖直墙面单位面积接收的太阳辐射量是个重要的基本参数,本文采用计算机编程的方法,来模拟计算此参数.算结果显示:在昆明,墙面方位角为±45°时,竖直墙面接收到的太阳辐射量最大.当方位角在-45°~45°之间变化时,竖直墙面单位面积上全年接收到的太阳辐射量在3.99×103MJ/(m2.a)~4.04×103MJ/(m2.a)之间变化;当方位角大于45°以后竖直墙面单位面积上全年接收到的太阳辐射量逐渐下降,最少为3.69×103MJ/(m2.a).更多还原

【Abstract】 In the application of the solar energy,the solar radiation gained by the facades of building is an extremely important parameter.This paper refers to the simulated calculation of this parameter through computer program.the results are as follows: In Kunming,the solar energy radiation received by the facades is the largest when the azimuth angle just reach about±45°.When the azimuth angle between-45°and 45°,the solar radiation received by the facade of building is in the range of 3.99×103 MJ/(m2·a) to 4.04×103 MJ/(m2·a).The solar radiation gained by facade wall decreased rapidly to 3.69×103 MJ/(m2·a) when the azimuth angle is greater than 45°.In a word,the solar radiation received by the facade of building in Kunming is very abundant.The investigation of this paper is valuable for the design and application of solar energy integrated with the building.更多还原
