中文摘要：

干燥物料需要消耗大量的能量。我国的干燥能耗占工业总能耗比例达到了12%。机械化程度低是我国干燥能耗大于发达国家的主要原因。将热泵技术应用于物料干燥节能效果明显,并且热泵干燥是一种温和的干燥方式,干燥产品品质好,干燥温度调节范围宽,干燥参数易于控制。相比于热泵干燥,太阳能干燥运行费用低,环境污染少,也得到了广泛的关注。把太阳能与热泵结合起来进行物料干燥相比原有单一热泵系统有较大改进和提高。论述了国内外太阳能辅助热泵干燥技术。

英文摘要：

Drying material ivill use a lot of energy. The energy consumption of drying takes up 12%of the total energy consumption of industpy in China. Tlve greater drying consumption in our country thanthat in the developed countries h caused by the loiv degree of mechanization. The heat pump technologyapplied, to the material drying can get an obvious energy saving effect, meanwhile^ the heat pump drying isa moderate drying method, ivith better drying product qualUy, wide adjusting range of drying temperature,and easier parameters control. Compared with, the heat pump drying, the solar drying operation cost is loiverivith less environmental pollution tvhich also received wide attention. Solar-assisted heat pump dryingtechnology has greater improvement compared to the original single heat pump system. The solar-assistedheat pump drying both at home and abroad is expounded.
