目前GB 50736—2012已给出中国北纬20°~50°地区的夏季太阳总辐照度,尚缺少北纬10°~20°之间低纬度地区的规范值。为解决该问题,对处于低纬度地区的永暑、西沙的太阳辐射数据进行统计整编,并根据中国太阳辐射基础数据的确定原则,在现行规范的基础数据上补充太阳高度角为3°、大气透明度等级为4时的太阳辐射基础数据;然后通过插值法与理论计算生成中国北纬10°和15°地区、大气透明度等级为4时的夏季太阳总辐照度表,为低纬度岛礁地区太阳辐照度研究和太阳能应用提供规范数据。
Abstract
Solar irradiance is an important basic parameter for building thermal design, HVAC design and solar energy utilization. At present, Design code for heating ventilation and air conditioning of civil buildings GB 50736—2012 provides the global solar irradiance for summer in the region of 20°-50° north latitude, but there is still a lack of standard values in the low-latitude region below 20° north. To solve this problem, the solar radiation raw data of Yongshu and Xisha, which is at a latitude of 9°40’N and 16°50’N respectively, are organized. Then the processed data are used to calculate fundamental data of solar radiation at a solar elevation of 3° and atmospheric transparency of level 4. Based on the supplemented fundamental data table, through interpolation and theoretical calculation, the global solar irradiance for summer is generated for the area at 10°N and 15°N latitude with atmospheric transparency of level 4. The results provide standard data for the research solar irradiance and application of solar energy in low latitude areas.
