摘要：
A plastics porous corrugated plate packing was proposed which had large specific surface area and was punched with holes on its surface. Cross-flow heat-source tower experiment system was established. The influence of air mass flow flux, liquid desiccant mass flow flux on the heat and mass transfer performance of porous corrugated packing was studied and compared with that of herringbone corrugated packing under the same conditions. The results show that the mesh structure of the porous corrugated packing promotes liquid film's crossflow on the both sides of the packing and perturbation of liquid film surface. When the air mass flow flux is 2.5 kg/(m2•s), the heat transfer coefficient of porous corrugated packing is 9.5% larger than that of herringbone corrugated packing and porous corrugated packing's heat transfer is 2 times larger than that of herringbone corrugated packing, which gives reference to enhance the heat and mass transfer and to reduce the volume of heat-source tower. © 2018, Central South University Press.
