摘　　要：在现行暖通设计规范中,围护结构负荷朝向修正率取值范围较大,且无法体现太阳辐照度地区差异引起的差别,导致不同地区设计计算结果与实际朝向负荷不相符。相关节能设计标准中亦未考虑朝向修正。综合考虑太阳能热能等级分区和建筑热工设计分区划分标准,选取典型城市,计算得到了适用范围广、较准确的负荷朝向修正率和节能朝向修正率。In the current heating design standard, the value scope of the correction factor for orientation of building envelope heating loads is rather large, and it cannot reflect the differences of solar radiation intensities in various regions which results in that the design calculation results fail to match the respect practical situation. The related energy efficiency design standard does not take the orientation correction into account. Synthetically considering graded solar energy zoning and building thermotechnical design zoning standard, chooses the representative city of every region. Calculates and obtains heating load and energy efficiency correction factors for orientation for wider and more accurate application.
