摘　　要：搭建了太阳能热水辅助热泵干燥系统,以马铃薯片作为干燥物料,在冬季进行了不同热水温度的太阳能热水辅助热泵干燥实验,以及单一热泵干燥实验。实验结果表明:当辅助热水温度为30℃时,太阳能热水辅助热泵干燥系统制热量与COP值高于基础组,也高于辅助热水温度为20℃和10℃组的值,证明太阳能热水辅助热泵干燥系统能有效的提高系统效率,且辅助热水温度越高,太阳能热水辅助热泵系统更节能;同时总结了系统制热量与COP值随着干燥箱内温度、“薯片”水分迁移量的变化呈曲线上升的趋势。A solar hot water assisted heat pump drying system was established.Potato chips were used as drying materials.Experiments of solar hot water assisted heat pump drying and single heat pump drying were carried out in winter.The experimental results show that when the auxiliary hot water temperature is 30℃,the average heat production,COP and energy saving rate of the solar hot water assisted heat pump drying system are increased by 3.82%,8.24%and 5.27%,respectively,compared with the single heat pump drying system,which proves that the solar hot water assisted heat pump drying system can effectively improve the system efficiency.At the same time,through the experimental analysis of the drying system,the auxiliary hot water temperature should be greater than 20℃,solar hot water can play the role of auxiliary heat pump unit to improve efficiency.
