低温储粮是一种具有广阔应用前景及实用价值的科学储粮方法。将太阳能制冷应用于低温储粮能有效节约常规能源。本文根据太阳能制冷系统的特点及仓内粮温分布规律,提出了采用太阳能制冷系统进行仓内空气隔离层(仓内粮堆上部空间)环流通风的储粮技术,并在中央储备粮扬州直属库进行了试验。结果表明:采用仓内空气隔离层环流通风冷却方式可有效地抑制高温季节仓内上层粮温的升高。在仓内上层平均粮温回升到15～20℃前将太阳能制冷系统适时地投入运行,能够实现准低温储粮。
Low temperature grain storage is a kind of scientific grain storage method with broad application prospect and practical value. Applying solar refrigeration to low-temperature grain storage can effectively save conventional energy. According to the characteristics of solar energy refrigeration system and the law of grain temperature distribution inside the warehouse, this paper puts forward the grain storage technology adopting the solar energy refrigeration system to circulate the air inside the warehouse (the upper space of the warehouse) Conducted a test. The results show that the circulation ventilation cooling method of air isolation in the warehouse can effectively restrain the increase of upper grain temperature in the high temperature season. In the upper compartment average grain temperature rose to 15 ~ 20 ℃ before the solar refrigeration system put into operation in a timely manner, to achieve quasi-low temperature grain storage.
