Ultralow-temperature-driven water-based sorption refrigeration enabled by low-cost zeolite-like porous aluminophosphate

Thermally-driven water-sorption refrigeration is a promising environmentally friendly technology, but finding suitable porous materials is challenging. The authors report a very high coefficient of performance using a low-cost zeolite-like aluminophosphate as a water sorbent, suitable for use with low-grade thermal energy.
