Rationale and Selection of a Distillation Subsystem for Water Reclamation from Urine

A selection of a distillation subsystem with a rotary multistage vacuum distiller (RMVD) and a heat pump (HP) for the system for water reclamation from urine for the international space station is substantiated. The results of computational/experimental analysis of specific energy for distillation with RMVD and HP of different type used are presented. The test results of an experimental system mockup are given. It is shown that the subsystem of a given type is stable in operation, features high condensate processing rate and low specific energy demand.
