研究了通风、环流一体化系统其中一种通风方式即吸出式环流控温通风过夏试验。由于冷源储存得当,实现了全过夏期间仓温控制在22℃以下,仓湿控制在35%以下,最高粮温控制在20℃以下,没有结露等任何不安全储粮现象发生,效果要优于纯空调储粮模式,而且在整个过夏期间,不需要排积热通风,窗户始终处于密闭状态,仅靠粮堆自身的冷源,大大降低对智能通风中排积热的依赖,这将极大地降低企业资金投入和维修管护,极大地改善保管员劳动强度,具有极高推广价值。试验仓保管的玉米第一年过夏纯电费为0.445元/t年,扣除新粮的均温均质通风和夏季排积热通风,实际综合费用为-0.33元/t年,第二年过夏综合电费为0.17元/t年。
The ventilation, circulation system integration one of the ventilation that sucked out of circulation temperature control ventilation over the summer test. Due to the proper storage of the cold source, the warehouse temperature control is below 22 ℃, the warehouse humidity control is below 35%, the maximum food temperature is below 20 ℃, and no unsafe grain storage occurs during the whole summer. It is better than pure air conditioning grain storage mode, and during the entire summer, does not require row of thermal ventilation, the window is always in airtight state, rely solely on its own cold source of grain reactor, greatly reducing the heat in the intelligent ventilation in the row, This will greatly reduce the capital investment and maintenance management and maintenance personnel greatly improve the labor intensity, with a very high value of promotion. In the first year of corn storage in the test warehouse, the pure electricity cost in the first year was 0.445 yuan / t. After deducting the average temperature of fresh food and ventilation in summer, the actual comprehensive cost was -0.33 yuan / t, the second year was over Summer comprehensive electricity is 0.17 yuan / t year.
