NOVEL ABSORPTION REFRIGERATION SYSTEM WITH A HOLLOW FIBER MEMBRANE-TYPE GENERATOR

摘要

In this paper a hollow fibre membrane-type generator has been introduced with a trial to be applied intothe vapour absorption refrigeration system (VARs). Since a hydrophobic hollow fibre membrane allows thepassage of refrigeration vapour and retains LiBr solution, it could substitute for the conventional generator ofVARs not only to be scaled-down and weigh-lighted, but also not to be influenced by vibration and slopingroad while driving.This study presents a parametric steady-state simulation model to look into a novel LiBr-water singleeffect absorption cooling cycle combined with a hollow fibre membrane-type generator. The numericalmodel is simulated based on the heat balance coupled with the mass transfer for the vacuum membranedistillation, and mass and energy balance for a whole novel absorption cycle. The simulation results areutilized to examine the effects of various working conditions on the cooling capacity and the Coefficient ofPerformance (COP).
