在自行设计的实验装置上，对扩散吸收制冷机气泡泵的抽气性能进行了研究。以R134 a-DMF（N，N-二甲基甲酰胺）溶液为工质，选取R134 a质量分数分别为20%、25%、30%和35%的4种不同内径（6 mm、8 mm和10 mm）的提升管进行实验。结果表明：（1）提升管内径为6 mm的气泡泵的泵送比最小，而提升管内径为8 mm和10 mm的气泡泵的泵送比相近。(2)抽运比随气体流量的增加而减小，随R134 a浓度的增加而增大。(3)生成温度随热输入的增加近似线性上升，随R134 a浓度的增加下降幅度不大，随提升管内径的增加下降明显。(4)系统压力随热输入的增加略有增加，但随R134 a浓度的增加而明显增加。所得结果对扩散吸收式制冷机气泡泵的设计有一定的指导意义。
The pumping performances of bubble pumps for the diffusion absorption refrigerators were investigated on the purpose made experimental setup. The R134a-DMF (N, N-dimethylformamide) solution was used as the working fluids and R134a mass fractions of 20%, 25%, 30% and 35% were selected for three lifting tubes of different inner diameters (6 mm, 8 mm and 10 mm). The results showed that: (1) The pumping ratio of the bubble pump with the lifting tube of 6 mm inner diameter was the smallest while those of 8 mm and 10 mm lifting tubes were similar. (2) The pumping ratio decreased with the increase of the gas flow rate but increased with the increase of the concentration of R134a. (3) The generating temperature increased approximately linearly with the increase of the heat input, decreased little with the increase of the concentration of R134a and decreased obviously with the increase of the inner diameter of lifting tube. (4) The system pressure increased slightly with the increase of heat input but increased obviously with the increase of the concentration of R134a. The results will be helpful to the design of bubble pumps for the diffusion absorption refrigerators.
