单压吸收制冷系统中气泡泵的研究进展

摘要

Single pressure absorption refrigeration is a technique that can use low grade heat source and is beneficial to environmental protection and energy efficient use. It has the very broad application prospect. Bubble pump is a critical component that makes the single pressure absorption refrigeration system work normally, provides power cycle for single pressure absorption refrigeration systems. So the study of the performance of the bubble pump to the whole operation of the system is of great significance. This paper introduced the working principle and bubble pump flow model and summarized the experimental research situation in recent years and influence factors of bubble pump lifting performance. Furthermore, prospective bubbles pump research was also presented.%单压吸收制冷能够使用低品位热源,是一种有利环保和能源有效利用的技术,具有十分广阔的应用前景.气泡泵是实现单压吸收制冷系统正常运转的关键部件,为单压吸收制冷系统的循环提供动力,因此研究气泡泵的性能对整个系统的运行具有重要的意义.文中介绍了气泡泵的工作原理以及流动模型,概括了近年来关于气泡泵的实验研究现状以及影响气泡泵提升性能的因素,并对气泡泵未来的研究进行了展望.
