SPACE OBJECT TEMPERATURE CONTROL SYSTEM Russian patent published in 2004 - IPC

FIELD: space engineering; control of temperature and humidity of gaseous media in pressurized compartments. SUBSTANCE: proposed temperature control system includes heating and cooling loops with liquid heat-transfer agent liquid activators connected through at least one intermediate liquid-to-liquid heat exchanger, control system, sensors showing pressure differential on liquid agent activators, sensors showing flow rate of liquid heat-transfer agents and flow regulator; provision is also made for bucket-type pump, unit for conversion of pressure of atmosphere of liquid compartment at point of delivery of gas-and-liquid mixture before centrifugal separator, centrifugal separator, second bucket-type pump, filter unit and activator of circulation of atmosphere in manned compartment of space object; inlet of first bucket-type pump is communicated through first and second valves with inlets of activators of circulation of liquid heat-transfer agent in heating and cooling loops; outlet of first bucket-type pump is communicated through third and fourth valves respectively with outlets of the same activators and outlet of first bucket-type pump is communicated through fifth valve with area of minimum flow section for conversion of pressure of atmosphere in liquid compartment of space object at point of delivery of gas-and-liquid mixture before centrifugal separator; outlet of this unit is communicated with inlet of centrifugal separator whose outlet is communicated with inlet of second bucket-type pump; outlet of this pump is communicated through sixth valve with inlet of first bucket-type pump and outlet of centrifugal separator is communicated through filter unit and atmosphere circulation activator with atmosphere of manned compartment of space object. EFFECT: possibility of creation of normal operating conditions for centrifugal pumps (liquid circulation activators). 2 cl, 1 dwg
