摘　　要：本文讨论了两种类型太阳能干燥器的通风系统以及集热器最佳面积配比,通过数学模型的计算与分析,得到了两个结论:(1)在回流式通风系统中,采用大回流比的设计,能有效地消除外界气象条件变化对干燥器运行工况的影响;(2)空气集热器面积的合理配比应以干燥器排湿风量为标准来确定。In this paper, two types of ventilation systems of the solar dryer and determination of optimum collector area are described. Through calculations and analyses using mathematical models, two conclusions are obtained which are very useful to designs of solar drying systems, namely, 1) in re-circulating ventilation system, when recirculating ratio ≥20 is adopted, the impact of outside meteorological changes on the operation of the solar dryer can be eliminated effectively; 2) optimum air collector area would be determined by reference to the amount of exhausted humid air of the dryer.
