北京理工大学珠海学院 2020 届本科生毕业设计太阳能氨水吸收式保粮系统设计/摘 要我国作为粮食产量大国，粮仓在我国占据着很重要的角色，本次新冠肺炎的爆发，多地开始新建粮仓。按照储粮性能可将粮仓分为气调仓、低温仓、准低温仓和一般常温仓，而传统的低温仓和准低温仓比较耗能，更有一部分偏远地区因为电力短缺让储粮很困难。而太阳能资源在某些偏远地区非常丰富，是解决这个问题的突破点。本设计以珠海本地的高大平房粮仓为例，设计了以太阳能结合氨水吸收式制冷机的保粮系统，充分利用低品位能源以及减少制冷机对环境的污染。同时得到广泛应用的话也可以解决偏远山区电力短缺的问题。此次设计，通过查阅相关资料，计算得出粮仓冷负荷，在这基础上对制冷系统和太阳能热水系统进行设计，同时合理的对系统设备进行选型并绘制出粮仓的平面结构图，最后进行本次设计的保粮系统进行经济性分析。此项技术大面积推广有利于充分利用低品位能源，减轻大型公共建筑耗能高以及偏远地区电力短缺储粮难的问题关键词：粮仓；氨水吸收式制冷；低品位能源；经济性北京理工大学珠海学院 2020 届本科生毕业设计Design of Solar Ammonia Absorption Grain Preservation SystemAbstract As China is a large grain production country, the grain silo occupies a very important role in our country. With the outbreak of new coronary pneumonia, new grain silos have been built in many places. According to the performance of grain storage, the grain storage can be divided into modified atmosphere storage, low temperature storage, quasi-low temperature storage and general room temperature storage, while traditional low temperature storage and quasi-low temperature storage are more energy consuming, and some remote areas are difficult to store grain due to power shortage . And solar energy resources are very abundant in some remote areas, which is a breakthrough point to solve this problem. This design takes the local tall bungalow grain storehouse in Zhuhai as an example, and designs a grain preservation system that uses solar energy co...
