根据不同季节的太阳高度角随地理纬度变化这一原理 ,确定畜舍塑料暖棚面与地面的最佳夹角 ,使冬季大寒 (最冷 )这天正午时分 ,太阳辐射的入射角与塑料棚面垂直 ,以其充分利用太阳的辐射热能 ,提高畜舍内的温度。通过对地处北纬 4 6°霍林郭勒市牧民一户牛舍和一户羊舍的温热环境和舍内空气质量的测定表明 ,大寒这天舍外气温 - 2 4～ - 10℃下 ,牛舍内的温度平均 8.2℃ ,羊舍内的温度平均 6 .1℃ ,空气质量在卫生要求的范围内 ,达到了防寒抗灾的目的
According to the principle that the elevation angle of the sun varies with the geographical latitude in different seasons, the best angle between the plastic shed and the ground is determined so that the incident angle of the solar radiation and the plastic shed Vertical surface, with its full use of solar radiation heat, raising the temperature inside the house. Through the determination of the warm environment and air quality inside a shed and a herd of cattle in Huolinguole city at latitude 46 ° north latitude, , The average temperature inside the barn is 8.2 ℃ and the average temperature inside the barn is 6.1 ℃. The air quality reaches the target of cold disaster resistance within the health requirements
