SPACE OBJECT AIR THERMOSTATTING SYSTEM Russian patent published in 2002 - IPC

FIELD: rocketry and space engineering; control of temperature and humidity parameters of spacecraft in the course of ground preparation at launch position, especially in winter when air sucked for thermostatting has low temperature and humidity requiring heating and humidification, i.e. proper and reliable conditioning. SUBSTANCE: proposed air thermostatting system is provided with fan, supply pipe line with filter and shut-off and adjusting fittings connecting the inlet of system with vertical pipe line laid over servicing unit and connected with access hatch of spacecraft, 1st and 2nd stage air cooler and refrigerating center connected with them, electric heater, thawing line of air coolers including thawing fan and thawing electric heater and control panel; proposed system is additionally provided with reservoir connected with supply pipe line and heat-insulated air humidifier connected with this reservoir by means of vertical pipe line fitted with adjustable gate; said air humidifier is made in form of steam generator consisting of cylindrical reservoir filled with distilled water and provided with sleeve and level scale, low and high level sensors; secured in lower portion of said reservoir are tubular electric heater units and steam heater made in form of tubular electric heater mounted inside sleeve and closed with hermetic cover; sleeve is connected with supply pipe line through outlet branch pipe and steam line. EFFECT: improved quality; enhanced efficiency and reliability due to humidification of air with pure heated steam free from condensed moisture. 3 dwg
