FIELD: space engineering; method of drainage of heat-transfer agents from hydraulic systems of space vehicle temperature control equipment provided with hydropneumatic compensators. SUBSTANCE: prior to bringing hydraulic main 1 in communication with vacuum, present volume of gas chamber of compensator 2 is measured and initial pressure equal to pressure of atmosphere in habitable compartments is built up. Then, after hydraulic main 1 has been brought in communication with vacuum, change of pressure of air in gas chamber of compensator 2 is checked and after pressure has been equal to 
, drainage of component is discontinued. Device for realization of this method has pneumatic main 1 which connects gas chamber of compensator 2 with habitable compartment and drain pipe line 7 which is used to bring hydraulic main 6 in communication with surrounding space (vacuum). Pipe line 7 is provided with two electromagnetic sensors 8 mounted in series with pressure pickup 9 fitted in between them. Pneumatic main 1 is provided with absolute pressure measuring device 3 and shut-off valve 4. Pneumatic main 1 terminates in pipe union 5 for connecting the external pressure source. EFFECT: high accuracy of calibrated drainage; avoidance of spillage of components in habitable compartments. 3 cl, 1 dwg
