利用浅层地能低温储藏粳稻的研究

RESEARCH OF USING SHALLOW GEOTHERMAL ENERGY FOR GRAIN STORAGE IN LOW TEMPERATURE

结合试验仓地质及生态条件,利用浅层地能低温,建造了基于地埋管式浅层地能采集方式的低温储粮系统,研究了运行过程中单位能耗和通风前后水分的变化,并与使用谷物冷却机的能耗情况进行了对比。研究结果表明:浅层地能在制冷方面具有显著的节能优势,能有效保证粮食品质,降低储粮成本,是一种适合大规模推广应用的廉价冷源,符合绿色储粮发展趋势。

Considering the geological and ecological conomon oi expertmc,~L ~, o-- energy, The grain storage system in low temperature had been built based on the way of bur3nng pipe to collect shallow geothermal energy. The unit energy consumption during the running process and the mois- ture change before and after ventilating had been researched, its unit energy consumption had been com- pared with domestic grain cooling machines. The research＇s resuRs indicate that： the shallow geothermal energy has obvious advantages in refrigeration and saving energy, it can effectively guarantee the quality of grain and cut down the cost of grain storage. It is cheap coldsource suitable for large--scale popularization and application , and it is in line with the development trend of green grain storage.
