摘要

研究横向谷冷通风技术在36 m×24 m大跨度平房仓稻谷储藏中的应用。结果表明:大跨度平房仓采用横向谷冷通风技术后,通风路径为传统通风系统的4倍以上,冷热交换更加充分,谷冷通风降温耗能低。降温后粮堆温度均匀性好,粮堆高度方向粮温基本一致,沿谷冷通风的气流前进方向温度梯度差平均不大于0.3℃/m。在大跨度平房仓稻谷储藏中应用横向谷冷通风技术冷却效率和降温均匀性更好。
        The application of transverse ventilation technology for cooling grain in long-span warehouse(36×24) was studied. The result showed that the ventilation path was more than four times of that by tradition ventilation, the cold-heat exchange more sufficient, with lower energy consumption. After ventilation the temperature in grain pile was more uniform in grain height direction.The average difference of temperature gradient along the cool air direction was less than 0.3 ℃/m. The cooling efficiency and temperature uniformity was better in long-span warehouse by transverse grain-cooling ventilation technology.
