Abstract
By constructing a set of visualization experimental platform for bubble absorption in the vertical tube, the influence of the working parameter changes on flow pattern change and absorption height in absorption process was explored for using R124/DMAC as working fluid. The absorption height can represent the absorption capacity of the bubble absorber. Low absorption height means high absorption capacity under the same conditions. Experimental results show that the absorption height is related to the refrigerant vapor flow rate, absorption solution flow rate, and its inlet temperature and mass fraction, the nozzle orifice diameter, absorption pressure and cooling effect. By increasing the solution flow rate and the absorption pressure, enhancing the cooling effect, decreasing the solution inlet temperature and mass fraction and the nozzle orifice diameter, all bubble absorption heights can be reduced and the absorption capacity of the absorber can be improved. By performing the multiple linear regression of experimental data, a correlation equation for estimating the R124/DMAC bubble absorption height was given within ±20%, error band.
