Solar Adsorption Ice Maker Using Maxsorb III/Ethanol — Field-Validated, Mosul, Iraq (Soheel et al., Env. Progress & Sustainable Energy 2026)
confidence: high
Source: https://doi.org/10.1002/ep.70510
Source: Wiley EP&SE (2026). Rare volume of field replication for this literature (most are one-off prototype runs). Credibility: High — peer-reviewed with measured field data; COP-definition caveat flagged.
Key numbers
- 1 m² collector; optimum: 0.8 kg ethanol/kg carbon, 3 kPa evaporator.
- 2.1 kg ice/day, evaporator sub-zero 5.8 h, max COP 0.583 (cycle basis, pending verification).
- +110% ice yield, +35.6% COP vs carbon–methanol (NORIT PK1) benchmark.
- Maxsorb III: 3045 m²/g BET, 1.70 cm³/g pore volume; low charge + low evaporator pressure won the test matrix.
Why it matters
The classic Pons/Guilleminot carbon–methanol ice maker baseline (~0.10–0.12 COP_solar, ~4 kg ice/m²·day under Trombe-era optimism; wiki records the realistic band) now has a directly-benchmarked successor pair. Ethanol sidesteps methanol toxicity and thermal decomposition above ~120 °C — a known kill-mode for solar carbon–methanol builds. Updates solar-adsorption-cooling and the working-pair guidance in diy-adsorption-chiller.
