一、通风低温储粮的现状应用风机将自然空气打入粮堆进行低温储粮在最近一段时间里发展较快.而以往是应用制冷获得冷源,根据所计算的冷负荷、送风量、处理空气方式进行送回风系统设计,使整个储粮区空气分布均匀,减少区域温差.其仓内温度和相对湿度参数,其基数和精度为13±2℃,65±10%;18±2℃,65±10%.日本有一种制冷常温仓,参数为22±1℃,65±10%,具有简易制冷设备.在我国由于成本高,不易推广.
First, the status quo of ventilation and low temperature grain storage Application of fan to natural air into the grain storage for low-temperature grain storage in the recent period of rapid development.In the past is the application of refrigeration to obtain cold source, according to the calculated cooling load, air volume, Air handling system is designed to return the air, so that the air distribution throughout the grain storage area is uniform and the regional temperature difference is reduced. The storage temperature and relative humidity parameters are 13 ± 2 ℃ and 65 ± 10% ℃, 65 ± 10% Japan has a room temperature refrigeration warehouse, the parameters of 22 ± 1 ℃, 65 ± 10%, with simple refrigeration equipment in China because of the high cost, not easy to promote.
