FIELD: oxygen storage and delivery systems.
SUBSTANCE: invention relates to systems for storage and delivery of oxygen on underwater vehicles and submarines with air-independent power plants. The cryogenic system is equipped with an oxygen supply loop to the fuel processor as part of a cryostat, which is connected by liquid and gas to the tank by cryogenic pipelines and in which a working and reserve submersible pumps are installed, a tubular heat exchanger fixed on the inner surface of an additional housing, an oxygen heater, a receiver and a warm the oxygen supply line to the fuel processor. The tubular heat exchanger is connected to the outlet of the pumps at one end of the cryogenic pipeline, and to the oxygen heater at the other end of the cryogenic pipeline. After the pressurization evaporator, an oxygen heater is installed, connected to the receiver for supplying oxygen to the electrochemical generator. The cryogenic pipeline for supplying liquid oxygen to the tank is connected directly to the tubular coil. The container with an additional outer casing is installed in a vacuum compartment made of two sealed partitions and an outer casing of the underwater vehicle.
EFFECT: invention allows providing a stable oxygen supply and increasing the period of drainless oxygen storage.
