Underwater vehicle life support system

Abstract

The invention discloses an underwater vehicle life support system which comprises a liquid oxygen storage tank, a gas-liquid separator, a deep freezer, a precooler, a dryer, a splitter, a throttle valve, a cooler and a compressor, wherein the liquid oxygen storage tank and the gas-liquid separator are both connected with the precooler by the deep freezer; the other outlet of the deep freezer is connected with the gas-liquid separator by a pipeline; cabin air enters the splitter to split; one outlet of the splitter is sequentially connected with the compressor, the cooler and the dryer througha pipeline; the dryer is connected with the precooler through the pipeline; the other outlet of the splitter is connected with the precooler through the pipeline; and the outlet of the precooler leadsto a cabin to provide cold air and oxygen to the cabin. The underwater vehicle life support system provided by the invention mainly comprises a heat exchanger, the compressor and the throttle valve,does not need conventional air conditioner and regenerative ethanolamine equipment, has simple composition equipment, and has advantages of simple and reliable structure, no need of complex equipmenttechnology or control technology, low investment, simple operation and control, and the like.

Description

technical field [0001] The invention relates to an underwater aircraft, in particular to an underwater aircraft life support system. Background technique [0002] The underwater vehicle life support system mainly includes: respiratory oxygen supply, CO2 removal, air conditioning and ventilation, atmospheric environment monitoring, man-machine-environment engineering. Conventional air-conditioning devices currently used in underwater vehicles are large in size, high in energy consumption, and loud in noise. In order to save energy, the operating time of the air-conditioning system is even limited underwater. The crew needs to constantly consume oxygen and expel carbon dioxide to breathe. To remove CO2, regenerative ethanolamine is mainly used. This equipment is large in size and low in efficiency. Leakage of ethanolamine will cause secondary pollution, and it can only maintain the concentration of atmospheric CO2 at a minimum of 0.5%. Through the human-machine interface, th...
