DEVICE TO CONTROL AIR HUMIDITY IN MANNED SPACE VEHICLE CREW COMPARTMENT Russian patent published in 2009 - IPC B64G1/48 F24F3/14 

FIELD: aerospace engineering.

SUBSTANCE: proposed device comprises heat exchanger-condenser (13) with intermediate moisture collector with its moisture chamber communicating with hydraulic circuit of SV thermal control system, while its air chamber communicates with crew compartment (1). Aforesaid intermediate moisture collector communicates, via condensate pump-out pump (17), with detachable condensate collector of SV thermal control system. Proposed device comprises two cartridges (7, 19) with reversible moisture absorbent, two airflow regulators (4, 11), bypass air duct (22) incorporating throttle flap (6) and distributor valve (16). Each cartridge incorporates sorbent heater. Inlet of every cartridge (7, 19) communicates, via air ducts, with the 1^st and 2^nd outlets of the 1^st airflow regulator (4) with its inlet communicating, via 1^st fan (2), with crew compartment (1). Outlet of each cartridge (7, 19) communicates, via air ducts, with the 1^st and 2^nd inlets of the 2^nd airflow regulator (11) with one of its outlets communicating with crew compartment (1) and the other one communicating with aforesaid air chamber of heat exchanger-condenser (13) and, further on, via 2^nd fan (14), with crew compartment (1). Air ducts, at the inlet of cartridges (7, 19), communicate via bypass air duct (22). Intermediate moisture collector of heat exchanger-condenser (13) communicates, via distributor valve (16) with water recovery system.

EFFECT: air drying at all stages of SV operation, reduced weight and power consumption.
