This is a sophisticated cooling system that uses a special refrigerant which operates at very low pressure at room temperature. It works by compressing the refrigerant in two stages, cooling it in between with a separate liquid circulation loop, and then condensing it to release heat. This design aims to make the cooling process more efficient, especially for demanding applications.
Why it matters: Since 2013, environmental regulations have increasingly favored refrigerants with low global warming potential. This design, optimized for refrigerants operating at negative pressures, could offer an efficient solution for these environmentally friendlier, but often more challenging, substances.
