FIELD: space engineering; filling liquid loops of spacecraft temperature control systems with de-aerated low-boiling heat-transfer agent.
SUBSTANCE: prior to filling the loop with heat-transfer agent, required amount of heat-transfer agent shall be drained to metering reservoir. Increased pressure satisfying definite hydrostatic conditions shall be maintained in lines. Filling device is additionally provided with unit whose inlet is connected to thermostatted reservoir filled with de-aerated heat-transfer agent and is connected with outlet hydraulic joint of unit by means of pipe line through valve and filter; outlet hydraulic joint is connected to inlet hydraulic joint of liquid loop of temperature control system. Connected between filter and valve are compound pressure and vacuum gauge, metering reservoir and evacuation line.
EFFECT: improved quality of filling the loop.
