Study on characteristics of water vapor absorption of a hollow fiber membrane-based absorber

摘要

As an attempt to apply vapor absorption refrigeration system to automobile, an adiabatic hollow fiber membrane-based absorber is proposed. By using the micro-porous hydrophobic hollow fiber membrane which has hydrophobicity, liquid lithium bromide solution is mechanically confined by the hydrophobic layer and flows through HFM Water vapor passes across the membrane layers, and is absorbed into the stream of lithium bromide solution. This study focuses on the experimental operation to investigate the characteristics of water vapor mass flux across the hollow fiber membrane under various operating conditions.
