FIELD: space engineering; temperature control systems of communication satellites; refrigerating plants.
SUBSTANCE: deaeration is performed in thermostatted reservoir. Closed cavity above liquid surface in reservoir is connected with vacuum pump by means of valve and adjustable throttle valve. Fitted between valve and adjustable throttle valve is pressure meter for measuring pressure in said cavity. Evacuation of this cavity is performed in stepwise manner at simultaneous measurement of temperature and pressure. Difference between measured steadied pressure and pressure of saturated vapor of liquid shall be minimum at measured temperature.
EFFECT: simplified construction of deaeration facilities; reduced losses of liquid in the course of deaeration.
