EXPERIMENTAL INVESTIGATION ON THE PERFORMANCE OF A LITHIUM CHLORIDE WHEEL

ABSTRACT
This work has investigated the influence of change in operation conditions on the performance of a Lithium Chloride (LiCl) wheel. A rigorous experimental rig that facilitates the measurement of temperature, pressure, pressure drop, relative humidity, airflow rate and rotational speed is used. The measurements covered balanced flow at a wide range of rotational speeds (0 - 9.8 rpm), regeneration temperatures (50-70°C), airflow rates (280-540 kg/h) and relative humidities (30-65%) at ambient condition. The influence of those operation conditions on the wheel sensible effectiveness and coefficient of performance (COP) are analyzed. The result revealed that a maximum COP occurs at a rotational speed of 0.2 rpm (12 rph). The results also concluded that Kays and London correlation is sufficient in the prediction of the effectiveness of the LiCl wheel. It represents the experimental data with an average absolute percent deviation (AAPD) of 2.16 and a maximum absolute percent deviation (APDmax) of about 6.00.
