From the viewpoint of the environmental friendliness and energy-saving, the thermal driven absorption refrigeration system is considered a good alternative to the compression system. However, the performance of the absorption system has been much lower than that of the compression system at present. To improve the performance of the absorber, which is one of the most critical components in the absorption systems, an experimental system for ammonia-water bubble absorption was established in this paper. As for open ammonia-water bubble absorption, under different ammonia vapor mass fluxes the changing laws of solution mass, solution absorption rate, ammonia vapor absorption rate and ammonia-water concentration in absorption process were studied and discussed. Meanwhile a reference is provided for subsequent research on effect of nano additives on ammonia-water bubble absorption process.
