摘　　要：结合金属氢化物的特点,提出了一种新型太阳能吸附式制冷循环系统;具体介绍了系统结构形式,建立了系统能量转换与分析模型,并对构成系统的各部件进行了分析;根据具体算例,计算了系统各部件的效率与损失,结果表明,系统具有较好的节能效果,且系统优化应以太阳能辐射量为基准,以提高金属氢化物系统中的氢气转化率为目标进行。系统优化的另一方向在于发展与其他太阳能利用技术相结合的复合式系统。Based on the metal hydride heat pump＇ s characteristics , a novel solar adsorption refrigeration system 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 exergy efficiency and the quantity about the exergy loss of the system were discussed based on an example. The results show that the system has a better energy - saving effect, and it is affected by the quantity of solar radiate 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 radiate energy. The other orientation of the system＇ s development is to use the system coupled with other solar energy technology.
