摘要
建立了一套以TFE（三氟乙醇）为制冷剂，TEGDME（二甲醚四甘醇）为吸收剂，He（氦气）为压力平衡剂的水冷式扩散－吸收制冷系统，并进行实验研究。结果表明，当热水温度达到112～135℃时，机组可正常制冷，平均制冷功率约0．32kW，最大达0．58kW；同时获取了各换热器的实际传热系数，为kW级扩散－吸收式制冷机组的设计提供理论基础。
An experimental study on a water- cooled diffusion -absorption refrigeration （DAR） machine working with TFE （2,2,2 -Trifluoroethanol） as refrigerant, TEGDME （Tetraethylene Glycol Dimethyl Ether） as absorber and helium as the auxiliary inert gas was presented. It was found that when the heating temperature reaches 112 - 135℃ ,the averaged cooling capacity is about 0.32kW with a maximum value of 0.58kW. The actual heat transfer coefficient of each heat exchanger component is obtained, which is very helpful for further development of the DAR system with kW - level cooling capacity.
