Simulation study of a hybrid absorber-heat exchanger using hollow fibre membrane module for the ammonia-water absorption cycle.
Author(s) : CHEN J., CHANG H., CHEN S. R.
Type of article: Article, IJR article
Summary
An innovative hybrid hollow fibre membrane absorber and heat exchanger (HFMAE) made of both porous and nonporous fibres is proposed and studied via mathematical simulation. The porous fibres allow both heat and mass transfers between absorption solution phase and vapour phase, while the nonporous fibres allow heat transfer between absorption solution phase and cooling fluid phase only. The application of HFMAE on an ammonia-water absorption heat pump system as a solution-cooled absorber is analyzed and compared to a plate heat exchanger falling film type absorber. The substantially higher amount of absorption obtained by the HFMAE is made possible by the vast mass transfer interfacial area per unit device volume provided. The most dominant factor affecting the absorption performance of the HFMAE is the absorption solution phase mass transfer coefficient. The application of HFMAE as the solution-cooled absorber and the water-cooled absorber in a typical ammonia-water absorption chiller allows the increase of COP by 14.8% and the reduction of the overall system exergy loss by 26.7%.
