- C133 Visualization and Measurement of Adsorbed Amount Distribution of Ethanol in Activated Carbon Adsorbent Bed
説明
It is important for a design of an adsorber to clarify adsorbed refrigerant distribution in adsorbent bed during transient conditions with adsorption or desorption, because the adsorption and desorption process is complex phenomena with heat and mass transfer and strongly effect on the cycle performance of an adsorption refrigerating cycle. Adsorbed refrigerant distributions in an activated carbon particle bed in a metallic rectangular vessel had been quantitatively measured by a neutron radiography method. Ethanol was used as the refrigerant. An umbra method using a checked neutron absorber grid was applied for a quantitative measurement. The measured mass attenuation coefficient of ethanol was 0.386 m^2/kg. It was confirmed from the measurement for an adsorption bed in adsorption equilibrium that the adsorption amount could be quantitatively measured by the method. From the experiments of adsorption and desorption process with heat transfer, it could be clearly visualized that the adsorbed amount in the adsorption process was strongly affected by the position of the heat-transfer surface. In the desorption process, the effect was relatively small, because the heat diffusion in the adsorption bed might be enhanced by regenerated superheated vapor flow.
