Abstract
In this study, numerical simulation on vapor flow in the absorber in an absorption heat pump have been performed in order to investigate the behavior of non-absorbable gas and its effect on absorption phenomena. Various factors affect the behavior of non-absorbable gas, such as heat and mass transfer due to vapor absorption and flowing down of the absorption solution. We clarify the dominant factors for the distribution of non-absorbable gas by decomposing the factors that affect the distribution of non-absorbable gas and understanding the individual effects. In this study, we focused on effect of behavior of vapor absorption in absorption solution. In particular, the difference in the distribution of non-absorbable gas due to changes in difference depending on the inflow direction of steam was investigated. As a result, it was found that a large amount of non-condensed gas stays on the downstream side.
