VENTILATION SYSTEM OF ORBITAL STATION SERVICE MODULE Russian patent published in 2000 - IPC

FIELD: space engineering; ventilation systems of long-term orbital stations. SUBSTANCE: according to invention, ventilation system includes conditioners located on sides of service module on side of transient compartment to instrumentation zone which is separated from living zone by air-tight bulkheads. Inlets of conditioners are communicated with interior of instrumentation zone and outlets are communicated with interior of living zone. Some ventilators of instrumentation zone are mounted on radiator outlet of gas-and-liquid heat exchangers of the temperature control system of station. This zone is brought into communication with inlets of respective conditioners through air ducts fitted with ventilators. Instrumentation zone is divided into two cavities. One cavity (on side of transient chamber) is used for arrangement of thermally stressed equipment and heat exchangers. Over perimeter of this cavity, air ducts are laid; inlets of these air ducts are connected with ventilators at outlet of above-mentioned heat exchangers. Their outlets are brought of heat generating equipment. Air ducts of other cavity (on side of transient compartment) are provided with air intake hatches. Living zone is provided with subsystem including mixers, collectors and air ducts with fittings communicated with respective components of proposed ventilation system. EFFECT: guaranteed blowing of instrumentation zone and comfortable parameters of living zone of orbital station; reduced power requirements. 2 cl, 2 dwg
