摘　　要：分析密集烤烟房热负荷的组成,以烤房整体为对象分析其传热传质过程,建立合理的烤烟房能耗模型,探究烤烟房负荷分布规律。以云烟97品种为例,计算其烟叶烘烤过程的逐时负荷。研究结果表明:烤烟房负荷分布规律主要受烟叶失水速率影响,与排湿负荷分布规律类似;最大热负荷出现在定色期后期;烤房的围护结构负荷随着时间的增长而增大,总量约占烤烟房热负荷总量的15%。This paper aims to analyze the constitution of the heating load of bulk curing barn and the heat and mass transfer process for the whole bulk curing barn and set up the energy consumption model to explore the load distribution of bulk curing ham. Calculating the hourly load in the process of tobacco curing by Yunyan97 as an illustration. The results shows that the load distribution is mainly affected by the dehydration rate of tobacco, which is similar to the distribution of humidity load; the largest heat load appeares in the later period of the color fixing stage; the envelope heating load increases with the growth of time, which amount is 15% of the amount of the heating load of the bulk curing barn.
