摘　　要：结合金属氢化物热泵的特点,提出了一种耦合氢能的太阳能热泵干燥系统。具体介绍了其系统工作原理及流程,建立了系统各设备的能量转换及炯分析模型;以干燥种子的算例分析了不同参数对系统性能的影响。结果表明,系统具有较高的除湿率(SMER)值,且其主要与太阳能辐射量大小有关;系统优化应以太阳能辐射量为基础,以提高金属氢化物热泵的(火用)效率为目标,而系统与太阳能蓄热技术的耦合运用是发展的另一个方向。Based on the metal hydride heat pump＇s characteristics a novel solar heat pump drying system coupled with hydrogen energy was presented. The models of energy conversion and exergy analysis were set up. The flow and working principles of system was introduced in detail. The effects of different parameters on the system＇ s performance were discussed based on an example of drying seeds. The results showed that the system has a higher SMER value, and it is affected by the quantity of solar radiation energy mainly. The goal of the system＇ s optimization is to increase the exergy efficiency of metal hydride heat pump, based on the quantity of solar radiation energy . The other orientation of the system＇s development is to use the system coupled with other solar energy technology.
