摘要：

Energy-efficient dehumidification systems are necessary to reduce energy consumption and CO2 emissions into the atmosphere. Desiccant systems could be an alternative to conventional air dehumidification systems based on direct-expansion units. In the present work, the main objective was to develop and experimentally evaluate a 3D printed desiccant system manufactured using green desiccant materials. Hence, the adsorbent capacity of three 3D printed desiccant materials were studied: polylactic acid (PLA), pine wood with PLA (PW-PLA) and olive pit with PLA (OP-PLA). The results showed that PW-PLA was the material with the highest adsorption capacity of those analysed, up to 12.7 % higher than OP-PLA. A fixed bed desiccant system was fabricated using PW-PLA filament and its latent energy performance was investigated under different inlet air conditions and low regeneration temperature, 50 degrees C. The evaluation of the energy performance of the 3D printed desiccant system revealed adequate moisture removal capacity values, up to 30 g/sm3, with low pressure drop, less than 552 Pa. These results show the promising potential of 3D printing and green desiccant materials for manufacturing ecological air dehumidification systems.
