一、概述朝向修正是多年来供暖设计计算中一个争论较大的问题。在1974年制订暖通规范之前,是按苏联的做法,即以南向为0,而对北向附加10％。采用这样的修正值时,南向室温过高,北向过低,温度相差很大,说明以这样的百分数给出的差值过小。因此,有些单位便自行对北向附加到30％,甚至更大。这样虽使南、北朝向房间的温度差别确实得
I. Overview The orientation correction is a major issue in heating design calculations over the years. Prior to the establishment of the HVAC specification in 1974, it was according to the Soviet Union’s practice, ie, the southward direction was 0, and the northbound direction was 10%. With such a correction, the southward room temperature is too high, the northward room is too low, and the temperature is very different, indicating that the difference given by such a percentage is too small. Therefore, some units will add 30% or even more to the north. Although this makes the temperature difference between the south and the north facing the room really
