A new technology for obtaining clean water from liquid waste in closed life support systems and equipment for its implementation has been developed. The main elements of the system are the original centrifugal distiller (CD), which ensures the efficiency of the system at arbitrary orientation of gravity, as well as weightlessness, with intensified heat and mass transfer processes and thermoelectric heat pump, which reduces the specific energy consumption of the system.

The comparative tests of multi-stage centrifugal distillers are conducted with two types of heat-pumps – mechanical steam compressor and thermo-electric heat-pump, advantages and lacks of their use are certain in the systems of life-support for space aircrafts with a crew onboard. Developed and executed measures on modernization of construction and separate elements of centrifugal distiller and thermo-electric heat-pump, that allowed to promote efficiency of their work.

Experimental research of heat exchange is conducted during condensation of water, chladone of R-141b and mixtures of chladones of R-22 and R-407С in a horizontal pipe with the passive intensifiers of heat exchange – wire rings and wire longitudinal scope at the circular, расслоенном and asymmetric flow of phases. The field of temperatures is measured in the vertical section of the thick-walled test area, passing through circular intensifiers.
