Water azeotropes can be used for spacecraft high-performance / freeze-proof heat pipes, loop heat pipes, and pulsating heat pipes. Related important applications include pumped single-phase and two-phase pumped loops, thermosiphons and loop thermosiphons, Rankine cycle power generation systems, i.e. power plants, reverse Rankine cycle refrigeration systems, especially ones for use in manned areas, and higher temperature reverse Rankine cycle refrigeration / air conditioning systems for electronics cooling systems.
The largest application for this technology will be next-generation freeze-proof commercial heat pipes for electronics cooling and air conditioning equipment. The technology would also be applicable to Rankine cycle power generation, reverse Rankine cycle refrigeration/AC systems, pumped single-phase and two-phase cooling systems, thermosiphons, loop thermosiphons etc.
