Application of heat-exchangeunits in binary return system for technology ground work developing of spaсecraft

Anon-board binary return system module, which is used as thermal control chamberinstrument for technology ground work developing of spacecraft, has beendeveloped. We provide the analysis of the specification of the binary returnsystem module. We present the advantages of mechanical pump-based temperaturecontrol chamber for heat transfer fluid injection by means of binary returnsystem module versus the single-phase module.
