英文摘要：

Plate falling film regenerator with a film-inverting configuration is a new type of regenerator that combines the plate falling film absorption technique with the film-inverting technique. Understanding its performance is very important for industry applications. This paper used a new type regenerator and a plate falling film regenerator for comparison. The design conditions of these two regenerators were the same. By solving the mathematical model, the heat and mass transfer characteristics were calculated and compared between the two regenerators at different flow rates of solution, inlet concentrations, inlet temperatures, generation pressures, and heating conditions. The comparison revealed that these two regenerators had different changes of performance under varying operation conditions. In the case replacing the plate falling film regenerator with the new plate falling film regenerator with film-inverting configuration, the differences in the performance of the regenerators under varying conditions must be taken into consideration.
