Abstract
With the aim of reducing the size and increasing the energy efficiency of absorption chillers, the use of microporous membrane technology in these systems is at present under study. In particular, the simulation of a H2O-BrLi absorber using porous fibers for the heat and mass transfer between the solution and the vapor phase is considered in the present work. Heat and mass transfer process are modeled by means of selected correlations and data gathered from the open literature. Using the model developed, a simulation of the absorber is performed using typical operating conditions of absorption cooling chillers.
