FIELD: aerospace industry.
SUBSTANCE: invention relates mainly to stationary refueling equipment of aerospace systems. Liquid oxygen from the storage tanks is piped through centrifugal pumps and a pressurization system to the rocket refueling system. The pressurization system contains a cylinder with a (liquid) cryoproduct supplied to its evaporator-heat exchanger, which includes a refrigerant condensation surface. The refrigerant circuit also contains a pump, an evaporator with an atmospheric air fan and an electric generator turbine, the output of which is connected to the specified condensation surface. The output of the cryoproduct evaporator-heat exchanger is communicated through a three-way valve with a pressurization pipeline for liquid oxygen tanks and with the gas cavity of the pressurization system cylinder.
EFFECT: generation of additional electricity due to the use of atmospheric air heat, which can be used to supply power to the pumps of the refueling system and other consumers.
