FIELD: spacecraft temperature control systems; spacecraft ground servicing.
SUBSTANCE: proposed device has drainage and filling tanks, filling line and spillage line which connect drainage tank with system being filled. Tanks are connected with vacuum unit and with compressed gas source by means of lines which are provided with valves and pressure recorders. Filling line is also provided with pump and valves disconnecting the inlet branch pipe of pump from filling and drainage tanks and outlet branch pipe of pump from filling pipe union of system being filled. Vacuum unit is connected with filling and spillage lines by means of additional lines which are provided with valves. Area of filling tank above heat-transfer agent surface may be connected with filling line via valve. Device may be provided with reservoir whose liquid cavity is connected with lower part of filling tank through valve and temperature and pressure recorders; gas cavity is connected with compressed gas source and vacuum unit through pressure recorder and valves. Liquid cavity may be also connected with filling line by means of valve behind the valve disconnecting the pump from filling pipe union. Pump inlet may be connected via valve with definite point of spillage line.
EFFECT: improved quality of filling procedure due to enhanced monitoring of gas content in filling line and high degree of evacuation of system at heat-transfer agent de-aeration.
