朝向修正耗热量地暖!
来源:http://www.cddyt.cn 日期:2020-01-19 发布人:admin
  朝向修正热量消耗是考虑到建筑物的太阳照射,对围护结构的朝向修正热量消耗的一种修正。
  Orientation correction heat consumption is a kind of correction of orientation correction heat consumption of enclosure considering the solar radiation of building.
  当阳光照射到建筑上时,阳光直接穿透玻璃获得室内的热量。同时,阳面围护结构较干燥,外表面及附近温度较高,围护结构将热量传递给建筑物的减速较少。方向校正方向是根据包络线的不同方向,具有不同的校正率。修正的热耗等于竖直包络线的基本热耗乘以相应的方向修正率。
  When the sun shines on the building, the sun directly penetrates the glass to obtain the indoor heat. At the same time, the outer surface of the enclosure is dry, and the temperature of the outer surface and the surrounding area is high. The direction correction direction is based on different directions of the envelope and has different correction rates. The corrected heat rate is equal to the basic heat rate of the vertical envelope multiplied by the corresponding direction correction rate.
  目前,地暖设计计算中不同朝向的修正率一般采用以下值。
  At present, the correction rates of different orientations in the design and calculation of ground heating generally adopt the following values.
  选择上述正朝向率是地面,应考虑冬季的光率、建筑物的使用和屏蔽的情况。对于冬季日比低于35%的地区,东南、西南和南下改正率,宜采用-10%-0%,东西不能改正。
  The above positive orientation rate is the ground, and the light rate in winter, the use of buildings and shielding should be considered. For areas with a winter to day ratio of less than 35%, the correction rates of southeast, southwest and south down should be - 10% - 0%, which cannot be corrected in the East and West.

  风增加了热量
  Wind adds heat
  风的附加热耗是在考虑外界风速的情况下,对围护结构基本热耗的修正。
  The additional heat consumption of wind is the modification of the basic heat consumption of the enclosure structure considering the external wind speed.
  在包络基本热流的计算中,外表面的换热系数对应的风速约为4。中国大部分地区冬季平均风速一般为2-3m/s。因此规定,在一般情况下,地暖是不用考虑风加的。只有建在高地、沿河、或沿海岸的建筑物。
  In the calculation of envelope basic heat flow, the wind speed corresponding to the heat transfer coefficient of the outer surface is about 4. In most areas of China, the average wind speed in winter is generally 2-3m / s. Therefore, in general, it is not necessary to consider wind heating for floor heating. Only buildings built on high ground, along the river, or along the coast.
