Operational rules extracted
- Keep drive-temperature fluctuation within ±3 °C.
- Shape ramps in steps (70→73→76 °C): +4.6% COP over direct ramp.
- Real fluctuating duty: up to −7% capacity, −19% COP vs constant-source ratings — stack this with hot-ambient derating (Madinah study: COP 0.53 vs 0.6–0.8 nominal) for a realistic field-COP picture in adsorption-limitations-and-mitigations.
- New use case: PEMFC waste-heat-driven cooling (CCHP).
