Summary

THE PAPER PRESENTS AN ANALYSIS OF AN INTEGRATED ABSORPTION MACHINE WITH A WATER HEAT-DRIVEN LIQUID DESICCANT DEHUMIDIFIER FOR AIR CONDITIONING SYSTEMS. A MATHEMATICAL MODEL FOR THE LIQUID DESICCANT UNIT IS DESCRIBED AND THE GOVERNING EQUATIONS ARE SOLVED. THE MODEL IS APPLIED TO THE DEHUMIDIFYING CHAMBER (DHC) AND THE REGENERATION CHAMBER (RGC) IN A COUPLED MODE. RESULTS SHOWED THAT THE COOLING WATER TEMPERATURE AND THE TRANSFER POTENTIALS ARE THE CONTROLLING FACTORS AFFECTING THE DHC WHILE THE MASS TRANSFER POTENTIAL AND THE ABSORBENT AIR MASS RATIO ARE DOMINANT IN THE RGC. FOR A 315/304 K (42/31 DEG C) DRY BULB TEMPERATURE/WET BULB TEMPERATURE OUTSIDE AIR, THE INTEGRATED SYSTEM HAS AN ESTIMATED OVERALL COP OF 1.21 FOR A SUPPLYOF HOT WATER AT 413 K (140 DEG C) FED TO THE GENERATOR AND A COOLING WATER SUPPLY AT 303 K (30 DEG C). THIS COP IS 50% HIGHER THAN THE COP FOR THE ABSORPTION CHILLER ALONE (0.81).
