Key findings
- Frames the central problem as low SCP/COP hindering commercialization — a bed-level transport problem, not capacity.
- SCP levers catalogued, all transport-focused: multibed/multistage, finned beds, coated and metal-additive beds (up to +40% SCP), aerogel structures, metal foam, TPMS beds (+12.4% vs finned), fluidized beds.
- Recurring mechanism for SCP gains = enhanced heat/mass transfer (reduced thermal resistance, faster cycle), not increased equilibrium uptake.
- Does not mention “fractal” or “hierarchical” geometry by name → fractal bed geometry is absent as a named design lever in mainstream adsorption-cooling reviews.
Relevance
The high-weight meta source for fractal-hierarchical-bed-geometry: confirms transport is the dominant SCP lever, and that “fractal” is a genuine white space in the design literature.
