摘要：

针对粮食就仓干燥的特点,提出一套由太阳能辅助热泵干燥装置、通风地上笼送风系统以及粮食翻滚搅拌机械组成的就仓干燥工艺,可实现粮食就仓干燥的低能耗性、短周期性、均匀性等。以昆明地区为试验基地,设计制造了一套太阳能辅助热泵就仓干燥系统,分析了其运行性能与干燥能耗情况。给定条件下,初步研究结果表明,太阳能分数为15%,系统COPS可以达到5.19,而单位能耗除湿量可以达到3.05kg/kWh。

Abstract:

For grain-bin drying, a storage drying process has been developed, which involves a set of solar-assisted heat pump, ventilation systems and grain mechanical stir. In this way, low-power consumption, short cycle time and uniformity can be achieved in the drying process. A solar-assisted heat pump on the dry storage systems has been designed and manufactured in a grain depot of Yunnan. The energy consumption performance of the unit is analyzed. Under given condition, the initial research result shows that solar fraction of the unit is higher than 15%, system COPs is 5.19, and the SMER can reach 3.05 kg/kWh.
