摘要
我国目前太阳能干燥器的总采光面积约为7200米~2,其中整体式太阳能干燥器约占三分之一。本文概述了整体式太阳能干燥器的结构、工作原理及热工性能。通过实验研究,提出以温升保证率、脱水率、脱水比及热利用效率作为太阳能干燥器热工性能的评价指标,并提出了太阳能干燥器热利用效率的计算方法及公式。针对实验干燥器,综合了该装置脱水率计算经验公式,给出了图线与表格。
Up to now, the total aperture area of solar dryers are about 7200 m2 in China, one third of them belongs to integrated solar dryer. In this paper the working principle, structure and thermal performance of the integrated solar dryer are discribed. The temperatuer rise, dehydration rate, dehydration ratio and heat utilizing efficiency are suggested as indexes to eveluate the thermal performance of the dryer. A method and a formula for calculating heat efficiency of solar dryer are presented.An empirical correlation for calculating dehydration rate of the experimental dryer is concluded and tables and figures are listed.
