气泡泵在单压吸收制冷系统中的研究进展

Research Progress of Bubble Pump in Single Pressure Absorption Refrigeration System

本文介绍了气泡泵的工作原理,总结了近年来国内外在单压吸收式制冷系统中气泡泵的研究进展。提出气泡泵的三种重要影响参数分别为结构形式、运行参数和工质,并对扩散-吸收式制冷循环和Einstern制冷循环在理论和实验研究两个方面进行了阐述。同时对影响气泡泵性能的因素以及气泡泵其他方面的研究进行了分类。最后,指出循环中工质的种类以及多管气泡泵中形成提升量的倍增需要更完善和深入的研究。

The principle of bubble pump is introduced briefly and a number of bubble pumps that apply to single pressure absorption re- frigeration system are summarized and discussed. Configuration, operating parameter and working fluid are presented as the important pa- rameters influencing the performance of the bubble pump. The theoretic and experimental research on bubble pumps with diffusion-absorp- tion refrigeration cycle and Einstein refrigeration cycle are provided. The factors that influence the performance of the bubble pump and re- search in other aspects are classified. Finally, more further research on different types of working medium and the multiplication of lifting capacity formed are pointed out in the future.
