The Effect of Absorber Packing Height on the Performance of a Hybrid Liquid Desiccant System

A hybrid system consisting of vapour compression unit, a liquid desiccant system, and a flat solar hot water collector were designed, fabricated and tested. This combination allowed for a separate control of humidity and temperature without energy penalty. Various packing heights of the absorber component were tested to determine the optimal performance of the combined unit. A 1000mm packing height with cross-sectional area of 600×600mm, proved to be the best height that gives promising improvements in the coefficient of performance of the vapour compression unit.
