TECHNIQUE TO DRY AIR FOR DEHYDRATION OF ANTENNA WAVEGUIDE AND GEAR FOR ITS REALIZATION Russian patent published in 2004 - IPC

FIELD: protection of antenna waveguides against effects of unfavorable environmental factors by supply of dehumidified air under excessive pressure into protected spaces.

SUBSTANCE: specific feature of invention lies in successive switching on of first or second absorbers correspondingly to mode of moisture absorption from air blown-through it and to mode of dehumidification of moisture absorber by its heating. Dehumidification of one absorber is carried out by portion of flow dried by another absorber with its preliminary heating. Outlet of dehumidified air of one absorber in proposed gear is linked between one pair of outlets of relief valves and outlet of dehumidified air of another absorber is linked between another pair of their outlets. Air pump air electric heater are placed is succession between inlets of bypass valves in path of air flow. Main line to supply dehumidified air is connected between inlet of air electric heater and outlet of air pump.

EFFECT: enhanced functional reliability and decreased manufacturing cost thanks to structural simplification.
