摘　　要：为了确定扩散吸收式制冷系统(DAR)热源温度与输入功率的关系,建立以氨-水-氦为工质的扩散吸收式制冷系统,采用对比实验,在两种加热方式下,对热源变化给系统带来的影响进行了研究,用温度曲线的方式描述了系统各参数的变化。实验表明,当精馏器入口温度达到140℃时实验达到最好结果。因此,对于DAR系统必须匹配合适的输入功率。To ensure the relationship between heating temperature and input power of diffusion-absorption refrigeration （DAR） , an experiment system of diffusion-absorption refrigeration was set up based on ammonia（refrigerant） and water（absorbent） as the working fluids, together with helium as inert gas. Experiments were conducted to measure the rising time and the generating temperature. Test curves were used to describe the running of system. The best result occurred when temperature in dephlegmator reached 140℃. The experiment indicated that the suitable input power was necessary for DAR.
