通过对机械通风系统中地上笼风网的两种设计类型:“山”型和“圭”型风网进行的机械通风降温和环流熏蒸综合储粮试验,发现两种风网类型都能达到预期效果,但“圭”型风网设计效果更为理想,通风均匀性得到提高,能耗降低,1∶1.5的通风途径比既能满足通风降温的需要,也适合于通风降水。 Through the mechanical ventilation cooling and circulating fumigation comprehensive grain storage test conducted on two types of ground cage net in the mechanical ventilation system: “mountain” type and “Gui” type wind net, it was found that both types of wind net can achieve the expected However, the design of “Gui” type wind net is more ideal, the ventilation uniformity is improved and the energy consumption is reduced. The ventilation ratio of 1: 1.5 can not only meet the needs of ventilation and cooling, but also be suitable for ventilation and precipitation.
