摘　　要：马铃薯原料库内含有大量的余热和CO_2等污染物,需要及时排出。在COMSOL Multiphysics 5.3a环境下,以马铃薯贮藏库为研究对象,建立置换通风系统的参数化模型,分析库内气体的流线场和温度场,得出热气流卷吸排出余热和污染物的运动形式,即中心截面在高度为0.8m处温度降至10℃并保持稳定。对马铃薯原料库中置换通风系统的设计具有一定的参考意义。Potato raw materials warehouse contains a lot of waste heat and CO2 and other pollutants,which need to be discharged in time.In the COMSOL Multiphysics 5.3 aenvironment,taking potato storage as the research object,aparametric model of displacement ventilation system was established.The flow field and temperature field of the gas in the reservoir were analyzed,and the motion forms of the residual heat and pollutant in the hot air flow were obtained.The temperature dropped to 10 ℃ and remained stable,when the height was 0.8 min the center section.It was of certain reference significance for the design of the displacement ventilation system in the potato raw material warehouse.
