【摘要】 该文研究了北京地区钢结构组合式种子仓房夏季的温湿度及其分布。测试期间 ,仓外最高气温 3 6.6℃ ,仓内最高平均空气温度为 2 7.4℃ ,种堆最高平均温度为 2 5 .8℃ ,仓内外最高空气温差达到 9.2℃ ,仓内空气与种堆最高温差 1.6℃ ;种堆上层温度高于下层温度 ,但温度梯度较小 ,最大温差为 0 .5℃ ;种堆最高相对湿度为 62 % ,表明该类型仓房内的温湿度条件能满足玉米、小麦等种子贮藏条件。仓房南墙内外墙体表面的最高温度差 2 0 .4℃ ,仓房北墙最高热流量为 67.0 W/ m2 ,南墙最高热流量为 12 0 .5 W/ m2 ,表明该仓房墙壁密封性能较好。最后对仓房管理和需要进一步研究的方向提出了建议。更多还原

【Abstract】 Experiments were conducted in steel structure seed store house in Beijing in summer to investigate temperature and relative humidity. In the test period, the maximum temperature outside is 36.6℃, the maximum average temperature of the air inside is 27.4℃, and the maximum average temperature of the seed is 25.8℃, the difference of the maximum air temperature between the outside and inside of the store house is 9.2℃, the difference between inside air and seed is 1.6℃; temperature of upper layer of seed is 0.5℃ higher than the lower one; the maximum relative humidity of seed is 62%, and this level can meet the condition of the seed store, such as corn, wheat; the difference of maximum temperature between both sides of the south wall is 20.4℃; and the maximum heat conduct of the north wall is 67.0 W/m 2, while the south one is 120.5 W/m 2. It indicates that the airtight capability of the store house is very good. Finally, the suggestions management and problems that need to be studied further are put forward.更多还原
